Andrew Miller was placed on the 15-day DL on Sunday after rolling his ankle pretty severely in Saturday night’s disaster of a loss against the Los Angeles Angels.
While most people think of Miller as the big-time bust prospect formerly of the Detroit Tigers, he has carved himself a pretty important role in the Boston Red Sox bullpen. He has established himself as a quality left-handed arm late in games for the Red Sox, and his injury leaves Craig Breslow as the lone healthy lefty reliever with any MLB experience on the Sox 40-man roster.
Drake Britton is on the 40-man, but was just called up from Double-A to Triple-A on Friday, and only has four relief appearances in his five year pro career.
The only other lefty reliever that has had any success in the big leagues in the Red Sox system would be the Australian Ryan Rowland-Smith, but his last stint was back in 2010 when he posted an ERA up near 7.00.
This could re-energize the Red Sox focus back to the trade market. Chicago White Sox‘ Matt Thornton is the most obvious option. He has served as a closer in the past and has a long track record of success in late innings. He has been in good form as of late, and the fact that he is 36 years old could make his a reasonably priced option.
There is another interesting option out there. The once-terrible Oliver Perez has been quietly lights-out for the Seattle Mariners. He has an ERA of 1.39 this year and has even recorded two saves.
