NL Pitchers: Buy Low & Sell High Candidates (6/22/09)

Monday, June 22nd, 2009

This time of year many fantasy baseball team owners look to trades in an effort to improve their place in the standings.  Of course, everyone’s ideal is to trade away players who will perform worse over the remainder of the season than they have year-to-date, while simultaneously trading for players who will perform better over the remainder of the season than they have year-to-date.

How should you assess a player’s year-to-date value vs. his forecasted remainder-of season value?  Using Fantasy Baseball Sherpa’s In-season Updates tool, an owner can quantify both of these values in an effort to identify players who are currently undervalued and overvalued.  Fantasy Baseball Sherpa assigns a score of 1.00 Sherpa Points to the league leader in each category.  All other players are assigned a score for that category based on their result relative to the league leader’s result.

For example, if the league leader has hit 26 HRs year-to-date, then a player who has hit 13 HRs year-to-date would be assigned a scoreof 0.50 Sherpa Points.  For ratio categories (e.g.- AVG, ERA) a proxy statistic is used.  A player’s scores in each category can be added up to determine the player’s Total Sherpa Points.  A player’s maximum score is equal to the number of categories used (note:  this maximum score will be different for Hitters and Pitchers if your league uses a different number of categories for Hitters and Pitchers).

Here are 10 National League Pitchers who are good buy-low candidates for a league using the standard 5 Pitching categories (Wins, Saves, Strikeouts, ERA, & WHIP) based on stats through games of Sun 6/21/09:

  1. Rich Harden, SP, ChC (2.13 Remainder-of-Season Total Sherpa Points - 0.66 Year-to-Date Total Sherpa Points = +1.47)
  2. Cole Hamels, SP, Phi (2.27 - 1.03 = +1.24)
  3. Roy Oswalt, SP, Hou (1.93 - 0.78 =+1.15)
  4. Johan Santana, SP, NYM (3.40 - 2.32 = +1.08)
  5. Hiroki Kuroda, SP, LAD (1.48 - 0.46 = +1.02)
  6. Jose Valverde, RP, Hou (1.52 - 0.56 = +0.96)
  7. Ricky Nolasco, SP, Fla (0.52 - -0.26 = +0.78)
  8. Carlos Zambrano, SP, ChC (1.99 - 1.24 = +0.75)
  9. Tim Lincecum, SP, SF (3.27 - 2.56 = +0.71)
  10. Ryan Dempster, SP, ChC (1.92 - 1.28 = +0.64)

Here are 10 National League Pitchers who are good sell-high candidates for a league using the standard 5 Pitching categories based on stats through games of Sun 6/21/09:

  1. Zach Duke, SP, Pit (0.84 - 1.88 = -1.04)
  2. Jason Marquis, SP, Col (0.75 - 1.55 = -0.80)
  3. Jonathan Broxton, RP, LAD (1.91 - 2.61 = -0.70)
  4. Livan Hernandez, SP, NYM (0.20 - 0.88 = -0.68)
  5. Jeff Weaver, SP, LAD (0.01 - 0.60 = -0.59)
  6. Johnny Cueto, SP, Cin (1.66 - 2.24 = -0.58)
  7. Randy Wells, SP, ChC (0.43 - 1.00 = -0.57)
  8. Chris Volstad, SP, Fla (0.51 - 1.02 = -0.51)
  9. Brian Wilson, RP, SF (1.34 - 1.83 = -0.49)
  10. Russ Ortiz, SP, Hou (0.06 - 0.55 = -0.49)

Of course, there are a number of reasons why a player’s performance over the remainder of the season may vary significantly from his performance year-to-date, including normal variation in results, injuries, changes in roles, etc.  By attempting to quantify both a player’s year-to-date and remainder-of-season results, we can take at least some of the guesswork out of identifying buy-low and sell-high candidates.

I’ll take a look at AL Hitters in my next post.

Top 10 Year-to-Date 5×5 Mixed League Pitchers (5/23/08)

Friday, May 23rd, 2008

In my previous post I ranked the Top 10 Year-to-Date 5×5 Mixed League Hitters for the first quarter of the season. In this post I’ll do the same for Pitchers. The Sherpa Point system gives each Pitcher a score ranging from 0 to 1.00 in each of the 5 standard pitching categories (W, SV, K, ERA, WHIP). Essentially, the league leader in each category is given a score of 1.00, while all other Pitchers’ scores in that category are calculated as the ratio of their result to the league leader’s result.

For example, if Brandon Webb leads the league with 9 Wins, he gets a Sherpa Point score of 1.00 in the Wins category; a Pitcher with 6 Wins gets a score of 0.67; a Hitter with 3 Wins gets a score of 0.33, etc. A proxy statistic is used for average-based categories (e.g. - ERA, WHIP, K/BB, K/9).

The maximum Pitchers’ score is equal to the number of pitching categories. Statistics are taken from games through Tues 5/20/08.

Without further delay, here’s the list of the Top 10 Year-to-Date 5×5 Mixed League Pitchers:

  1. Cliff Lee 3.34 (Preseason Projection was 0.26)
  2. Brandon Webb 3.03 (3.23)
  3. Cole Hamels 2.92 (2.50)
  4. Edinson Volquez 2.77 (0.13)
  5. Shaun Marcum 2.66 (0.93)
  6. Tim Lincecum 2.59 (1.85)
  7. Ervin Santana 2.50 (0.42)
  8. Ryan Dempster 2.48 (0.59)
  9. Carlos Zambrano 2.36 (2.34)
  10. Daisuke Matsuzaka 2.34 (2.13)

Yes, it’s early, but even at this stage in the season it’s obvious that my Preseason Projections for Cliff Lee (50 IP, 3 Wins, 4.68 ERA, and 1.43 WHIP) were just a bit off. The Innings Pitched projection is obviously the driver - based on his performance the last 3 years, I didn’t believe he’d stick in the Indians’ rotation this year. Live and learn!

Webb and Hamels were in my Preseason Top 10, while Zambrano (13th), Matsuzaka (29th), and Lincecum (41st) all made my Preseason Top 50. However, the other 5 Pitchers on this list can all safely be termed “surprises”; I’ll venture a guess that if you have 2 or more of them on your roster (entirely possible), you’re probably sitting near the top of your league’s pitching standings.

Many notable names are missing from this list: Johan Santana (2.17 vs. Preseason Projection of 4.00); Jake Peavy (2.13 vs. 3.62); C.C. Sabathia (0.76 vs. 3.14); Roy Oswalt (0.61 vs 2.93); John Smoltz (1.41 vs. 2.70); Dan Haren (2.24 vs. 2.62); Aaron Harang (1.96 vs. 2.53); Erik Bedard (1.30 vs. 2.47). Just in case you’re curious, Jonathan Papelbon (1.89 vs 2.27), who ranks 24th Year-to-Date is the highest-ranked Closer; J.J. Putz (0.49 vs 2.32) was the highest-rated Closer (15th) in my Preseason Projections.

There is still plenty of time left for the Cliff Lees and the Ryan Dempsters to regress towards their expected values, and there’s plenty of time left for the C.C. Sabathias and Roy Oswalts to pitch the way most experts expected them to. I’ll be updating these rankings and comparisons for both Hitters and Pitchers periodically throughout the season.

Of course, lists like these are all well and good, but they don’t answer the obvious follow-up question: what should you expect these Hitters and Pitchers to do for the rest of the season?

I’ll begin to answer that question in a series of posts beginning early next week.

Until then,

Trading aces? (4/9/08)

Wednesday, April 9th, 2008

With just over a week gone in the 2008 baseball season the sky is officially falling. Those who drafted/bought C.C. Sabathia, Roy Oswalt, Jason Bay, J.J. Putz, Robinson Cano etc., are wondering why these players are off to lousy starts. Those who drafted/bought Johnny Cueto, Nate McLouth, Mark Reynolds, Livan Hernandez, Jason Kendall, Kerry Woods, etc., are congratulating themselves on their foresight. So, is your team doing as well as expected? If not, what should you do now?

Predictably, many fantasy baseball columnists are now churning out (or, more likely, recycling from last year) columns on how 10 games is too small a sample size to draw conclusions, how you shouldn’t make any panic moves, blah, blah, blah. The more adventurous (or less lazy) among them actually develop lists of players off to hot/cold starts and offer their expert opinions on which players will continue to over/underwhelm, and which ones will “regress to the mean”. Very little of this is helpful to you in your effort to manage your fantasy team, and unless you’re reading these pieces for entertainment purposes, you’re better off ignoring them.

Put it another way - if these same players had the same results over a 10 game stretch in July or August, would you notice? Assuming you did, would you be concerned enough to make a change to your roster? Probably not. Unfortunately, human nature being what it is, we generally give more weight to events that take place at the very beginning of the season (aka “Tuffy Rhodes Syndrome“) or at the very end of the season (aka “Tom Glavine Syndrome“).

So, is there any reason to consider making trades this early in the season? Some experts advise fantasy team owners to sit on their hands until at least the end of May before hitting the “Submit Trade” button unless your roster is decimated by an injury. I disagree. In addition to injuries, there are at least two other reasons to explore potential trades even this early in the season: (1) To shore up weak categories, and (2) To take advantage of another team owner’s desire to make quick and sweeping changes.

First, let me explain what I mean by shoring up weak categories. Do not judge which categories you’re weak in by the results of the first 10 days of the season. Rather, go back to the analysis you did on your team immediately following your draft/auction. Trust the instincts you had at that time over the reaction you currently have now that 10 games are in the books. Before a draft/auction I set a goal to assemble a team that can finish in the top third in every category. If I can achieve that kind of balance, there’s a good chance I’ll finish at the top of my league. Of course, trades, free agent acquisitions, and waiver claims are also necessary to maintain/improve your team during the course of the season, but without a good draft/auction, you’re digging yourself a deep hole that’s almost impossible to climb out of. Identify your post-draft/auction weaknesses and address them as soon as you are able.

Regarding the second reason to make trades at this point in the season, there’s at least one owner in every league who seems to panic and make an early-season trade that ultimately hurts their team more than it helps. Don’t let that be you! Case in point - last year I saw someone who panicked after Garrett Atkins got off to a slow start, then traded Atkins and Johan Santana for Alex Rodriguez and the overachieving Boof Bonser. Not surprisingly, the owner who received Atkins and Santana finished much higher in the standings at the end of the year.

Not every trade will be that one-sided, nor should it be. I obviously want my team to be better after a trade than it was before the trade; however, I don’t want the other owner to have buyer’s remorse to the point where they’d never want to trade with me again. Here are my recommendations in executing a trade, particularly early in the season:

  1. Assess your roster’s strengths and weaknesses. The earlier you are in the season, the more weight you should be giving a player’s preseason projected performance vs. his actual season-to-date performance. Of course, you need to be mindful of injuries and role changes (e.g. - everyday players who lose their jobs, newly-minted Closers, etc.)
  2. Assess your leaguemates’ rosters’ strengths and weaknesses. The obvious goal in doing so is to find several potential trading partners (not just one!) whose strengths match up well with your weaknesses, and vice versa.
  3. Send out trade feelers without making formal proposals. Initiate contact with specific owners. One of my fantasy sports pet peeves is owners who update their “Trading Block” page with a list of the categories they’re weak in, followed by a list of the players they’re willing to trade in order to improve their team (usually their weakest players). Sorry, I’m not trading you A-Rod and Carlos Zambrano for Pedro Feliz and Jose Contreras. As with most other things in life, you’re much more likely to get what you want if you ask for it rather than wait for it to come to you.
  4. Sort through the responses to your trade feelers, then make a specific proposal where it makes sense to do so. Most trade talks will die after the previous step. If you do identify an owner who seems interested in discussing matters further, throw out an initial proposal. This should not be your “best offer”, but it should be good enough that the other owner isn’t insulted and actually has to give your offer some serious thought. It’s fine to pursue this stage with multiple owners simultaneously, even if you’re offering the same player(s) to several of them.
  5. Negotiate. Expect the other owner(s) to counter your initial proposal - that’s part of the game. Keep a sense of humor about this - after all, we’re talking about fantasy sports here, not a life and death matter!
  6. Assess your options. After some finite period of time you’ll get a good sense of whether owners are willing to pull the trigger on a deal or not. Trust your instincts here too - if your potential trading partner is constantly hedging or stalling, you’re probably better off moving on. Compare the impact of a trade to the impact of adding a player through a free agent bid or waiver wire claim.
  7. Decide. While it may seem like a waste of time to come this far, then decide not to complete a deal, it’s not. The adage “sometimes the best trades are the ones you don’t make” applies just as much in the fantasy sports world as it does in the professional sports world. At the very worst you’ll receive a more accurate read on how your fellow owners value your players, as well as how they value their own players. You may unknowingly be sowing the seeds for a future trade. If you decide to complete a deal, don’t look back! If the player you’ve just traded away hits three home runs in a game or pitches a complete game shutout, let it go. You’re making the trade for the rest of the season, not just for the next game or two.

Until next time,
