Darren O'Day put on DL one day after suffering hamstring strain

BALTIMORE -- The Orioles have put reliever Darren O'Day on the 15-day disabled list because of a strained right hamstring.

The veteran right-hander suffered the injury covering first base in Wednesday's game against the Boston Red Sox. Since coming to Baltimore in 2012, the 33-year-old submariner has become a key part of an Orioles bullpen that currently ranks second in the American League with a 2.79 ERA.

Last year, the Orioles' setup man went 6-2 with a 1.52 ERA and six saves, and he was named an All-Star for the first time in his career.

One of the premier free agents on the market this past offseason, O'Day resigned with Baltimore, inking a four-year, $31 million contract. In 22 appearances this season, he's 2-1 with a 3.15 ERA and two saves but has already given up as many home runs (five) as he did all of 2015.

Right-hander Mike Wright, who was sent down to triple-A Norfolk on Thursday, has been recalled to take O'Day's spot on the 25-man roster.

O'Day becomes the third key Orioles player currently on the DL, joining shortstop J.J. Hardy and starter Yovani Gallardo.
