The Hardball Times has a piece today about sluggers who are struggling early, and the possibilities of them being hampered by injury. One guy mentioned is Mark Teixeira...THT says, in part:
This got me thinking...if his knee is bothering him, the reduction of the leg drive would most likely show up when he's hitting lefty (and pushing off with his left leg) than when he's hitting righty.
The numbers thusfar (insert your standard sample size warning here):
Hitting lefthanded: .179/.321/.284
Hitting righthanded: .375/.423/.500
Hmmm. You have to wonder if, with his knee bothering him, he wouldn't be better off hitting just righthanded for the time being.
