Jokes aside, wasn't it around 2012 when he had some injury problems and it looked like he would retire only to hit a third wind? I know in 2009 he struggled as well.
He had a wrist injury in 2008. He struggled badly in the first two seasons of 2009 (.623 OPS in April, .520 (!) in May) before turning it around (he batted .264/.356/.548 over the remaining four months).
