The Giants placed reliever Jeremy Affeldt on the DL (retroactive to 4/28/12; eligible to return on 5/13/12) with a sprained ankle. To take his place on the 25-man roster, they purchased the contract of one-time Giant P Travis Blackley from AAA Fresno.
Blackley has been in the Grizzlies' rotation. He last pitched for the Giants in 2007.
To make room for Blackley on the 40-man, the team designated OF Tyler Graham for assignment.
Graham was added to the 40-man in the offseason. He was on the DL with an injured shoulder, only playing in five games in 2012. He was expected to be disabled for a few more weeks.
There is now a 10-day window for another team to claim Graham, or the Giants to either trade him, release him or to outright him back to the minors. Because of his injury, it may be moot.
The Grizzlies have yet to announce a replacement on their 25-man for Blackley. His place in the rotation may be filled by Matt Yourkin, who started for the Giants Monday night. Yourkin had been a reliever thus far in 2012, but was the spot starter last night in wake of the Giants' doubleheader on Monday, April 23. Eric Hacker was called up to be the big leauge spot starter, leaving an opening for the Grizzlies to need a spot starter as well.
Another option the Giants could have utlized was recalling P Dan Otero, and not have to clear a spot on the 40-man. Because there was a player placed on the DL, Otero woudl be exempt from his 10-day minimum minor league option.
