Red Sox place Vicente Padilla on 15-day disabled list

The Boston Red Sox today placed right-handed pitcher Vicente Padilla on the 15-day disabled list (retroactive to August 6) with right arm tightness and recalled right-handed pitcher Clayton Mortensen from Triple-A Pawtucket.  Mortensen will be active for today's game against the Rangers at Fenway Park.

The announcement was made by Executive Vice President/General Manager Ben Cherington.

Padilla, 34, is 4-1 with one save, a 4.62 ERA (20 ER/39.0 IP) and 43 strikeouts compared to 11 walks over 41 relief appearances for Boston this season, including a 3.38 ERA (11 ER/29.1 IP) in his last 32 games since May 6.  The right-hander leads the team with 20 holds, fourth most in the American League, and four wins out of the bullpen, tied for seventh most in the circuit.  He has stranded 88.5 percent of inherited runners (23 of 26), the third-best rate among AL qualifiers.  Padilla owns a 108-91 record with six saves, a 4.32 ERA (749 ER/1,560.1 IP) and 1,113 strikeouts in 371 career Major League outings (237 starts) with the Diamondbacks (1999-2000), Phillies (2000-05), Rangers (2006-09), Dodgers (2009-11) and Red Sox (2012).

For Mortensen, 27, this is his fifth Major League stint of the season.  In 10 appearances for Boston this year the right-hander is 1-0 with a 1.17 ERA (3 ER/23.0 IP) and 17 strikeouts while holding opponents to a .169 clip (13-for-77).  He has also appeared in 24 games for the PawSox in 2012, all in relief, going 5-3 with two saves, a 1.91 ERA (8 ER/37.2 IP) and 36 strikeouts.  Acquired by Boston from Colorado in January, Mortensen has appeared in 34 Major League games (13 starts) with the Cardinals (2009), Athletics (2009-10), Rockies (2011) and Red Sox (2012), going 5-8 with a 4.35 ERA (57 ER/118.0 IP) and 67 strikeouts, including a 2.54 ERA (14 ER/49.2 IP) in 21 Big League relief appearances.
