Red Sox general manager Ben Cherington continued to stockpile pitching depth at the Triple-A level when he announced the signing of Jose De La Torre, David Carpenter and Sandy Rosario to minor league contracts.
Carpenter, who was acquired from the Blue Jays as compensation in the swap that brought manager John Farrell to Boston, and Rosario, who was claimed off waivers from the Miami Marlins earlier this offseason, have live arms that need work with harnessing command. De La Torre, who was obtained from Cleveland in the Brent Lillibridge trade last season, is the brightest pitcher of the trio and received an invitation to spring training.
De La Torre, who turned 27 in October, has allowed just 15 home runs in 339 minor league innings and has averaged more than one strikeouts per nine innings over six seasons in the Mets, Indians and Red Sox organizations.
He posted a 2.45 ERA in 12 outings at Pawtucket after arriving from the Indians, where he split time between Double-A Akron and Triple-A Columbus. De La Torre owns a 2.84 ERA and a 1.24 WHIP in his minor league career.
Carpenter, a 27-year-old right-hander, logged a 2.93 ERA and a 1.48 WHIP with 29 strikeouts in 27.2 innings for the Astros in 2011, but he struggled to a 8.07 ERA between the Astros and Blue Jays in 2012.
Inconsistent control has plagued Carpenter just as it has Rosario, another 27-year-old right-hander. Rosario has 319 strikeouts with a 3.48 ERA and a 1.32 WHIP in 310 innings over seven minor league seasons. In 10 games over three Major League seasons with the Marlins, he has a 15.26 ERA and a 3.26 WHIP, so obviously his stuff has not translated to big league success.
