Mark Ellis out for season

"Oakland second baseman Mark Ellis is out for the season with a torn labrum in addition to the separated shoulder he suffered in a collision with Bobby Crsoby. Frank Menechino is sidelined with a leg problem, but right now Billy Beane is prone to let Menechino have the job. However, the chances are good that Beane will try to find a second baseman who can hit lefties [should be righties](Geoff Blum can, for instance) and use Menechino against lefties."

he was one of the best defensive 2Bs in the league last year, so this is quite a blow to the A's.
