Curtis Granderson’s Plate Appearance Distribution by Pitcher Handedness
From 2007 through last night.
| Year | rPA | rwOBA | lPA | lwOBA | rPA/lPA |
| 2007 | 543 | .426 | 133 | .217 | 4.08 |
| 2008 | 470 | .389 | 159 | .319 | 2.96 |
| 2009 | 511 | .382 | 199 | .221 | 2.57 |
| 2010 | 143 | .358 | 84 | .232 | 1.70 |
Year: Duh
rPA: Plate appearances vs. RHP
rwOBA: Weighted on-base average vs. RHP
lPA: Plate appearances vs. LHP
lwOBA: Weighted on-base average vs. LHP
rPA/lPA: Ratio of PAs vs. RHP and LHP (rPA divided by LPA). Higher means a higher percentage of his PAs came against righties.
I’ll again make the point that we can’t yet assume that Granderson’s current career platoon split is what we should expect from him going forward because research shows you need 1000 PAs vs. LHP by a LHB to really know his platoon skill.
I’ll also make the point that a player can contribute in ways beyond the batter’s box in defense and baserunning.
That being said, if you want at least a partial explanation for why Granderson’s had trouble getting going so far this year beyond the simple fact that’s it’s only been 227 PAs, the fact that a much higher percentage of his PAs are coming vs. LHP looks to be at least part of the problem.
Update: So why are the Yankees seeing so many LHP? Blame Canada.
| Tm | lBF | rBF | %lBF |
| NYY | 1076 | 1929 | 35.8% |
| BAL | 818 | 2428 | 25.2% |
| BOS | 731 | 2529 | 22.4% |
| TBR | 532 | 2576 | 17.1% |
| TOR | 1504 | 1681 | 47.2% |
| AL East | 3585 | 9214 | 28.0% |
lBF: Batters faced by left-handed pitchers
rBF: Batters faced by right-handed pitchers
%lBF: Percentage of total batters faced by left-handed pitchers
The AL East total there does NOT include the Yankees. Also, FWIW:
| Tm | lBF | rBF | %lBF |
| AL East | 3585 | 9214 | 28.0% |
| AL Central | 3716 | 11996 | 23.7% |
| AL West | 4431 | 8242 | 35.0% |
| AL - Yankees | 11732 | 29452 | 28.5% |
| NL East | 4539 | 11337 | 28.6% |
| NL Central | 5385 | 13796 | 28.1% |
| NL West | 3735 | 12174 | 23.5% |
| NL Total | 13659 | 37307 | 26.8% |
So AL West teams throw the most lefties on a percentage basis.
Another Update: LHP vs. RHP split for home/road Yankee games:
| split | lBF | rBF | %lbf |
| home | 541 | 1140 | 32.2% |
| dnys | 568 | 1009 | 36.0% |
