One of the most debated issues in our game is the relevancy of the countless split stats that are readily available with just a few clicks on the web. With sabermetrics becoming increasingly used, there seem to be more and more ways to analyze, and attempt to predict, player performance. That said, I’ll outline the three splits most worthy of consideration while doing daily fantasy baseball research.
This information should prevent you from committing one of the ultimate no-nos when it comes to daily fantasy baseball preparation: “digging too deep.” I’ve seen it from so many players, both new and old. They think so long and so hard about so many different variables that their thinking becomes clouded. We’ve all heard the classic slogan “go with your gut,” and while I’m not advocating this completely, I do think there is something to be said for not over-thinking things. I’ve found that some of the best, most profitable teams I’ve put together, have come from very basic research in a reasonably short amount of time.
A quick note. Not included in these splits decisions are past week performance and specific pitcher vs. batter stats. If you’ve been reading me, you know I advocate these two statistical measures more than any other. If you haven’t, then shame on you, but also have a quick look at last week’s Movin’ On Up and previous article Step your prep up.
So here they are, the three most relevant splits, in no particular order.
This is the most obvious, and most used split stat in daily fantasy baseball. If you spend any significant time in the forums or chats of the various sites, it will become clear to you that the first thing that pops into the heads of the experienced player is the dominant hand of the hitter and the dominant hand of the pitcher he is are facing. But while this is the most relevant split, it is also the most misinterpreted.
The biggest misinterpretation is that lefties can’t hit lefties. This is not the case. While some lefties look lost against lefty pitchers (see, Adam Dunn), others hit them quite well—so well in fact, that they could give you a leg up in your match-up over a competitor who blindly doesn’t play Adrian Gonzalez because he is facing crafty southpaw Ted Lilly. In reality Gonzalez has a career OPS of .933 against Lilly in more than 20 plate appearances.
The same type of assumptions can be easily made for pitchers, along with complete ignorance to pitching statistics. To stick with our Red Sox examples, lets use Kevin Youkilis. He thrashes typical left-handed pitching, to the tune of a .328 batting average and an OPS of over 1.000 over the past three years. Both those statistics are significantly higher than his stats versus righties over that same period. So some would automatically roster him against the likes of say, C.J. Wilson. But not so fast. Mr. Wilson has a very respectable ERA of 2.65 versus righties in 2011. And not only that, he has given up pnly extra base hit to Youkilis in his career. Bet you didn’t know that.
So when using lefty/righty splits make sure to analyze the guy in the batters box as well as the man on the mound. You might find some interesting things if you take the time to dig deep enough. Here’s a top five list you might find useful as you using lefty/righty splits in the future:

There are many, many things that you must consider when deciding whether to value the home/away stats of any individual player. Many variables that can skew these stats one way or the other have absolutely nothing to do with a player playing at home or away from home. Some of those will be presented in the next section that discusses stadium-specific hitting. Others include weather (temperature and precipitation), playing through injury and things as simple as pitcher match-ups But home/away splits are a variable on their own, independent from the stadium aspect, and these splits can be very telling for certain guys. These stats are most relevant when sustained over a long period of time. Some players just hit better with the support of fans and others may get ridiculed in their home stadium, making them far more successful on the road.
Here are three players who have shown statistically significant differences in batting average between home/away stats since 2002
You can find pretty much anything you need on Fangraphs. Check it out and see if you can find anything significant that I missed. That’s the fun thing about splits, there’s always more to be found. But for every significant thing you find, you will encounter and have to determine the relative unimportance of countless other splits. It’s a test of your inner patience. Good luck!
Stadium-specific hitting statistics
Last, stadium factors. We all have preconceived notions about which parks are hitter friendly and which ones are not. And for the most part you are probably spot on. But make sure when you pick players based on what stadium they play in, you also factor in the other variables on that given night (like weather and pitcher). Just to put your mind at ease, I wanted to present you with the three most hitter-friendly, three most pitcher-friendly, and four most neutral fields in the league, as rated byThe Sporting News.
