There's just a 40% chance the A's make Mark Ellis available, a source tells Jon Paul Morosi of FOX Sports (Twitter link). The A's, who already traded infielder Eric Patterson, will choose between Ellis' $6MM option for 2011 and a $500K buyout if he's still in Oakland at the end of the season.
Ellis would probably draw interest if GM Billy Beane made him available. The 33-year-old is hitting .288/.355/.374 this year, and has been an average defender at second base over the course of the past two seasons (according to UZR/150).
The Red Sox and Phillies have injured second basemen and could have interest in Ellis, who missed time with a hamstring injury early in the year. The Yankees are looking for bench help, but Ellis has $2.75MM remaining on this year's contract and that's a lot of money to spend on a reserve.
