With the announcement coming down just last night that Fangraphs has added splits to their stat pages, I thought it would be fun to look at interesting 2009 splits for each likely member of the 2010 Yankees. I will look at hitters now, and address pitchers later today. I will likely expand on some of these over the next few weeks. Remember, when you do splits, you are essentially splitting the sample, such that small sample size caveats apply.
Home: wRC+ : 167
Away: wRC+: 101
For those that are not aware, wRC+ is the Fangraphs version of OPS+, and is likely a better measure because it corrects the OBP/SLG weighting problem inherent to OPS. Regarding Posada, I was surprised to see how stark his home-road splits were, considering that he is a switch hitter and is not a dead pull hitter. He certainly made use of the short porch, notching a 271 wRC+ when batting as a lefty and hitting the ball to right field.
Fly Balls: .327/.320/.991
According to Fangraphs, league average in these categories:
Teixeira did significantly better than average on flies and worse than average on grounders. The ground ball data suggests he needs to keep the ball in the air, but I wonder about the flyball data. It may be possible that shots that would qualify as liners in other parks are being ruled flies when they clear the wall in Yankee Stadium, such that much of his power is being shifted from the liner category to the fly ball category.
Low Lvg. FB% 30.2
Med Lvg. FB% 34.1
High Lvg. FB% 48.1
The more important the situation, the more likely Robbie was to hit a fly ball. This strengthens my belief that he is trying to do too much in those spots. It is important to note that players only have 60-80 high leverage at bats a year, such that the sample is small. As such, take this more of an observation of what happened last year than something that necessarily represents a trend.
ISO to Left: .105
ISO to Center: .082
ISO to Right: .278
Almost all of Jeter’s power was to the opposite field. That is a startlingly large split in power, and was a greater dichotomy than that in Jeter’s career ISO.
Low Lvg. HR/FB: 20.3
Med Lvg. HR/FB: 21.1
High Lvg. HR/FB: 45.5
A-Rod hit flyballs with about the same frequency in all situations. However, when the game was on the line, he took the ball out of the ballpark with much greater frequency. Unclutch, indeed.
Low Lvg. BB/K 1.02
Med Lvg. BB/K 1.29
High Lvg. BB/K 1.42
Johnson did will in high leverage spots overall, but I found his increased patience in those spots fascinating. When the situation was important, Johnson became more likely to strike out, but also more likely to take a walk.
Home ISO: .168
Away ISO: .316
Most of Swisher’s power came on the road, despite the New Yankee Stadium being a homer haven. If he can maintain something close to his road performance while bumping his home power a bit, he could find himself at 35 or more home runs.
Home HR/FB: 8.9%
Away HR/FB: 15.7%
Granderson simply did not get much bang for his buck on fly balls in Comerica. His road numbers were significantly better than his home numbers, particularly against lefties, giving hope that he might return to the superstar that he was in 2007 once he gets out of the large ballpark in Detroit.
wRC+ v. L 115
wRC+ v. R 93
Gardner actually played fairly well against lefties. If he continues that and Granderson is not able to turn it around against lefties, might Randy Winn become the platoon caddy for Granderson rather than Brett?
wRC+ v. R 102
wRC+ v. L -9
Of course, if Winn cannot turn this around, he will not be caddying for anybody. He has pretty solid career numbers against lefties, so this seems to be an anomaly, but he did hit significantly fewer line drives and more fly balls against lefties, both bad signs.
