Archive for BABIP

You may have noticed that FanGraphs now feeds batted ball data, courtesy of Baseball Info Solutions, into its leaderboards. The day the data appeared, my mind buzzed with ways they could be useful in improving our understanding of a hitter’s batting average on balls in play (BABIP).

Mike Podhorzer already augmented previous attempts at devising an equation for expected batting average on balls in play (xBABIP) for hitters by incorporating elements of a hitter’s power, speed, plate discipline and batted ball tendencies. So, with fresh numbers in hand, I embarked on a journey to further improve the ever-evolving xBABIP. However, I sought to do so by using only batted ball data. Basically, I intended to develop a convenient xBABIP equation, one that can be computed using almost entirely variables found on the same page.

After a year in which one-time Brewers shortstop-of-the-future and current Royals man-up-the-middle, Alcides Escobar, batted .293 with a .331 on-base percentage and 35 stolen bases, expectations were running awfully high in fantasy circles. His lack of power was dismissed in favor of the potential for more speed and there seemed to be little concern over the fact that his walk rate stayed at its woeful 4.2-percent while he saw a minor spike in strikeouts. Some pointed to his inflated .344 BABIP but his supporters pointed to his minor league batted ball data and his above-average contact rates. But when Escobar finished the season with a dismal .234/.259/.300 slash line and swiped just 22 bags, the supporters ducked for cover as the naysayers (cue obligatory comment from John Elway) reveled in the glory of being right.

Consider this a bit of a twist on what usually appears in this space. Rather than a player who is outproducing his expected value, today we have a player who is being rapidly added in leagues where he will probably cease to provide the kind of value for which his new owners are hoping. Especially in light of reports that Chris Johnson wouldn’t lose playing time now that Freddie Freeman has returned off the disabled list at the expense of former platoon-mate Juan Francisco, there seems to be a sense that he’s worth rostering in nearly 100 percent of leagues; in the last seven days, Johnson has been added in over 72 percent of ESPN leagues and the only reason he isn’t atop the Yahoo! trends is because he’s already owned in a majority of leagues at this point. While Johnson may well have more value than it appeared he would on draft day, he’s unlikely to finish as one of the 10-12 best third basemen this season.

The obvious red flag with Johnson is his .468 BABIP, which is so ripe for regression it has almost spoiled on the tree. Since 1995, just two players have finished a qualifying season with a BABIP over .400: Manny Ramirez, who had a .403 mark in 2000, and Jose Hernandez, who managed just a .288 batting average despite a .404 BABIP in 2002. So yes, regression is coming, but expecting Johnson to slide all the way down to .300 is probably a mistake for a couple of reasons. Read the rest of this entry »

2012 wasn’t supposed to look anything like 2011 for the Miami Marlins as they added a whole mess, and I do mean mess, of new salaries to help inaugurate their new digs in downtown. But for all their trouble, the Marlins finished 69-93 having been outscored by their opponents by some 115 runs, which was actually slightly worse than 2011’s 72-90 finish with a -77 run differential.

2013 won’t look much like 2012 whether the Marlins manage to extricate themselves from the cellar of the NL East or not simply by virtue of the roster shuffling that has already started. Despite signing a rich deal last winter, Heath Bell was one of the very first players moved this offseason, and Ozzie Guillen wasn’t far behind him out the door. In fact, about the only things that really came as advertised were Giancarlo Stanton, the home run monstrosity and Jose Reyes. Read the rest of this entry »

Scroll a little more than halfway down Zach Sanders’ End of Season First Base Rankings, and there at number 31 you’ll find Kansas City Royals first baseman Eric Hosmer with a measly $1 value attached. If you stood by Hosmer this past season, you probably think that Zach was a little too generous with that ranking and perhaps that dollar value is a bit much. After all, as far as disastrous seasons go for over-hyped players, this one may not take the cake, but it definitely ranks up there. Read the rest of this entry »

Negotiating trades in fantasy baseball can always be tough in competitive leagues.  Everyone is trying to gain the upper hand and each time you ask for that better starting pitcher or that more powerful outfielder, you end up taking some kind of grief for over-valuing your own players.  So why not try and get that extra boost in numbers from a low-profile spot like behind the plate?  Negotiate a deal and then try to throw in your over-performing catcher for their under-performing one who you think has the potential to improve.  You just might be able to squeeze some more out from their end.  Looking at early season BABIP and xBABIP, here’s a look at some “throw-ins” you just might want to try out… Read the rest of this entry »

Ryan Theriot had a surprisingly good season, both in real and fantasy baseball. He hit a somewhat impressive .307/.387/.359, striking out 15 times less than he walked and stealing 22 bases (granted, he was caught 13 times). However, his season was fueled by an unsustainably high batting average, and if that BA regresses next season, he could hurt your fantasy team.

Theriot’s BABIP was .335 this year; however, his expected BABIP was a mere .291 (according to a new model I introduced). If we adjust his batting average to be in line with his expected BABIP, his BA falls all the way to .267. Considering that Theriot hits for virtually no power and drives in very few runs, this drop in BA would have a huge impact on his overall value.

The lower BA would result in a lower OBP, which would lead to fewer runs scored and fewer opportunities to steal bases. Additionally, Theriot was downright awful at stealing bases in 2008, getting caught in 37% of his attempts. Unless he improves upon this, it’s possible that the Cubs will become more reluctant to let him steal, depressing his stolen base total even further.

There is little evidence to suggest that the BABIP information about Theriot is incorrect. His career batting average in the minors was .271; his BABIP in the minors was .309. There’s no reason to think that either of these things has suddenly improved significantly, and there’s no reason to think that Theriot can consistently beat his expected BABIP (for reference, in 2007 his actual BABIP was .283 and his expected BABIP was .311).

Considering that nearly all of Theriot’s value revolves around his inflated batting average, it would be a good idea to avoid him in most fantasy drafts next season. That’s not to say he’ll be entirely without value, but just make sure you value him as a ~.270 hitter who may not even reach last year’s SB total, rather than a ~.310 hitter with the chance to surpass 30 steals.

Remember when Paul Konerko was an elite hitter? It wasn’t that long ago that the White Sox first baseman hit .313/.381/.551 with 35 homers. In fact, Konerko posted that line in 2006, after eclipsing the 40 homer mark in both 2004 and 2005.

Of course, one the tenets of baseball analysis is that hitters – especially one dimensional sluggers, tend to age rather rapidly. However, Konerko is only going to be 33 years old, and has shown signs that he may not have run out of steam entirely.

Last season, Konerko had a rather mediocre line of .240/.344/.438 with 22 homers in 122 games. However, as we will see, Konerko was struck with a bout of bad luck, and also showed significant signs of life towards the end of the season.

The first thing to note about Konerko’s 2008 was his poor luck with balls in play. His BABIP was a mere .247, much lower than his career average of .285. His line drive percentage remained high, at 21.5%, right in line with his career LD% of 21.4%. Furthermore, he struck out at the same rate as he has over the last five seasons (he struck out in 18.3% of his at bats in 2008 – his K rate has remained between 18% and 19% every year dating back to 2004), and he actually had the highest walk rate of his career as well.

According to the BABIP model I introduced with Chris Dutton, Konerko’s expected BABIP was .280 this year (incidentally, Konerko is a good example of a player for whom the “old” model of predicting BABIP – namely, adding .120 to line drive percentage – is a poor indicator of true BABIP, as our “new” model has consistently predicted Konerko’s BABIP to be far lower than the “old” model). The 15% difference between Konerko’s actual BABIP and his expected BABIP was the 14th biggest difference among all full-time players in 2008 – in other words, Konerko was extremely unlucky on balls in play.

Furthermore, Konerko’s 2008 was plagued with injury woes. Konerko strained his oblique and was put on the disabled list in June – he was hitting a paltry .215/.325/.368 with 8 homers at the time, so it’s very possible that Konerko tried to play through the injury before finally being placed on the DL (in fact, in the 30 games prior to the DL, Konerko hit only .202/.281/.330).

After coming back from the injury on July 8, Konerko hit like himself again. In the final 60 games of the season, Konerko posted a line of .267/.366/.514 with 14 homers – while striking out 37 times and drawing 30 walks. He suffered a sprained knee in September but managed to play well despite it; both the knee and oblique should be fully healthy in 2009.

At age 33, Konerko will remain an injury risk, and likely will not be able to perform at the same level that he did in his peak. However, rumors of his demise are greatly exaggerated. Konerko suffered from a tremendous amount of bad luck on balls in play that should regress next season, thus raising hit batting average.

Furthermore, although he may not hit 40 homers, he still has enough power to hit 30-35 bombs, and will be helped (as always) by the fly-ball-friendly confines of US Cellular Field. As Konerko demonstrated in the last three months of 2009, when healthy he can still be an offensive force. And he can probably be had relatively late in most drafts, as less-astute owners will assume that he’s washed up.

Paul Konerko is an excellent sleeper for fantasy baseball in 2009.

Finally given the chance to play every day in 2008, the 23-year-old Matt Kemp had quite a season: he hit .290/.340/.459 with 18 homers and 35 steals. Kemp sported a very high BABIP for the second season in a row, but all indications are that Kemp should be able to maintain this high BABIP in the future.

Kemp posted a .363 BABIP this year, thanks in large part to the fact that he hit line drives 23% of the time. In fact, Kemp has posted consistently high BABIPs throughout his career: his 2007 BABIP was an absurd .417, while his BABIP in the minors has ranged from .345 to .417. Thus, while Kemp’s BABIP is quite high, there’s no reason to think that he can’t maintain this level of BABIP going forward. Thus, while his .290 batting average may seem a bit high upon first glance at his BABIP, there’s a very good chance that it represents his true ability, rather than a fluke.

Kemp has always been young for his level throughout the minors, and indeed was only 23 last year. Any 23-year-old that can slug .459 is a heck of a player, and is likely to develop more power in the coming years. Given that Kemp is very toolsy, while 18 homers is pretty good, there’s reason to expect increased power output in the future. There’s certainly no guarantee that Kemp will hit more homers in 2009 than he did in 2008, but it’s fairly likely.

Furthermore, Kemp’s 35 stolen bases are extremely valuable for fantasy purposes. He was caught 11 times, and Joe Torre has shown a willingness to turn him loose on the basepaths that he will likely demonstrate once again in 2009. Kemp didn’t slow down in the second half of the season, and therefore it’s unlikely that he will run less in 09 than he did in 08.

Finally, it appears that Kemp has locked up a full-time position in the Dodgers outfield. Going in to 2008, there was a lot of consternation amongst folks on the internet about how the Dodgers’ outfield situation would play out. It was clear to many that Kemp should be playing every day, but some questioned whether Joe Torre would bench Kemp in favor of established veterans like Juan Pierre or Andruw Jones. That didn’t happen, and Kemp responded with an excellent season. Kemp’s production in 2008 makes it quite unlikely that Torre will bench him for an extended period of time in 2009, so Kemp’s playing time is likely secured even if he goes in to a slump.

Although I was concerned at first about his BABIP, there’s every reason to think that Kemp will be able to maintain a high BABIP in the future. If he cuts down on the strikeouts (he struck out in over 25% of his at bats in 2008), his batting average could rise even further. He’s a good bet to attempt at least 40 stolen bases, and there’s reason to believe that he could produce even more homers next year. Although the secret is out about Kemp, I believe that many people may not recognize just how good he could be, and therefore he may be undervalued on draft day.

Nick Swisher was quite a disappointment in 2008.

After being traded from Oakland to Chicago, many (including myself) predicted improvement from Swisher, thanks to his friendly offensive environment on the South Side. Instead, Swisher produced a miserable season, hitting .219/.332/.410 with 24 homers. He did benefit from playing in US Cellular Park, but that benefit was negated by a terrible performance in games on the road: Swisher hit .247/.361/.517 with 19 homers at home, but only .189/.301/.294 with five homers on the road.

Recently, the White Sox traded him to the Yankees, where he is currently slated to be their everyday first baseman. And I think the Yankees are in for a pleasant surprise, as Swisher is quite likely to rebound in 2009.

Swisher’s BABIP in 2008 was very low: .251, to be exact. In the previous three seasons, Swisher’s BABIP had been .308, .287 and .266, respectively. However, Swisher actually hit the most line drives of his career in 2008, hitting liners 20.9% of the time. While he did strike out a lot, his strikeout rate was in line with his career rate, as was his walk rate. Swisher’s skill in hitting the ball and hitting it with authority didn’t change; rather, he simply experienced a lot of bad luck.

In a study I recently co-authored, I found that Swisher was one the unluckiest players on balls in play in 2008. I found his expected BABIP to be .294, much higher than his actual BABIP. If we credit Swisher for his lost hits, his 2008 line becomes .249/.356/.447 – not much different from his career line of .244/.354/.441 (and his career line includes his miserable 2008 stats).

In other words, Swisher’s 2008 season, once adjusted for the bad luck he incurred, was exactly in line with his previous seasons. There’s no reason to think that his inherent ability to hit the ball changed much, as evidenced by his stable strikeout, walk, and line-drive rates; therefore, we have every reason to expect Swisher to improve in 2009, thanks to regression to the mean.

Swisher is never going to hit for a very high batting average, but he’s quite unlikely to hit .219 once again. Even though he is no longer playing in the friendly confines of US Cellular Field, Swisher should be good for 25-30 homers (assuming he plays every day), and should put up a decent number of RBI and runs scored, thanks to the other players in the Yankees lineup.

Swisher is not a fantasy superstar, but he’s significantly better than he showed in 2008, and is therefore very likely to be underrated. Don’t hesitate to take him late in drafts, and don’t be surprised when he produces like he did from 2005-2007.
