Yankees beware: Jeter's production is likely to decline.
See data for Jeter for full seasons 2008, 2009, 2010 and for 2011 both before and after Jeter's return from Florida following his rehab from injury. Jeter's improvement is inexplicable.
I looked at:
BA: batting average
OBP: on base percentage
SLG: slugging average
OPS: OBP + SLG
Jeter's percentage improvements in 253 PA (plate appearances) after returning compared with 293 PA before:
BA OBP SLG OPS
29.89% 20.23% 42.14% 30.98%
Here are his actual 2011 numbers:
age BA OBP SLG OPS
36 0.260 0.324 0.324 0.649
37 0.338 0.3895 0.461 0.850
dif 0.0777 0.0656 0.137 0.201
Jeter's OPS his three previous seasons:
Jeter's 2010 OPS is exactly the same as his 2011 before Jeter left the Yankees to rehab: .649, the lowest of his career.
What the heck happened in Florida and don't tell me Jeter adjusted his batting swing?
The sample size is approaching a half season so the question is legitimate. For his career Jeter does tend to improve in the second half: OPS .820/.846. For the last three seasons:
Jeter snapped out of a slump that had lasted through the second half of 2010 and the first half of 2011, from which Jeter exploded after turning 37. How often does that happen without an extra boost?
Jeter has cleared .900 OPS twice:
His 2011 post injury OPS is .850 through 9/10/11. In only six of Jeter's 16 full seasons did Jeter have OPS greater than .850.
What the heck?
