Word is that Izturis is working on a healthier lifestyle to prevent a second half decline. According to Gurnick, Izturis "batted .305 through July and finished at .288, hitting .259 over that period, leading to speculation that his 5-9, 187-pound frame can't quite take that kind of workload." Uhh, okay. If the speculation were up to me, I don't see how that would enter into the discussion. His BABIP was down from .328 through July to .308 after, which given the sample size is pretty typical variation and not sufficient to suggest fatigue. And it's not clear to me that fatigue or Izturis' small frame is responsible for his striking out more in August and September, which was as big a factor in his batting average decline as his lower BABIP. In reality, his poorer numbers from August onward are more a factor of chance and cherry-picking; July was Izturis' best month ever, so a sample which excludes it will be low. Here's a chart, where BIP/AB is balls in play per at bat and NipBA is batting average normalized for a .300 BABIP:
AB H AVG HR K K/AB BIP/AB BABIP NipBAWhile his numbers for August after July aren't as good as before July, the difference isn't significant as it's well within the bounds of normal variation.
