Red Sox Add LHP Drew Pomeranz and Option RHP William Cuevas

The Boston Red Sox today added left-handed pitcher Drew Pomeranz to the active major league roster. To make room, the club optioned right-handed pitcher William Cuevas to Triple-A Pawtucket following yesterday's game against the New York Yankees. Pomeranz will wear number 31 and is expected to start Wednesday's game against the San Francisco Giants at Fenway Park beginning at 7:10 p.m.

President of Baseball Operations David Dombrowski made the announcement.

Pomeranz, 27, went 8-7 with a 2.47 ERA, a .184 opponent batting average, and 115 strikeouts in 102.0 innings over 17 starts for the Padres this season. Selected by Manager Terry Collins to replace Noah Syndergaard in this year's All-Star Game, the left-hander made his Midsummer Classic debut on Tuesday, allowing one hit in a scoreless inning of work. He leads NL pitchers this season in opponent batting average and ranks among major league leaders in opponent slugging percentage (3rd, .288), opponent OPS (2nd, .555), and earned run average (5th). A native of Collierville, TN, Pomeranz has surrendered zero earned runs in seven of his starts, tied for most in the majors.

Cuevas, 25, has made three relief appearances for the Red Sox over three major league stints this season, going 0-1 with a 3.60 ERA (2 ER/5.0 IP). The Venezuelan native has also pitched in 15 games (all starts) with Pawtucket, going 6-3 with a 3.38 ERA (34 ER/90.2 IP), 57 strikeouts, and a .238 opponent batting average. A non-roster invitee to Red Sox spring training this year, Cuevas was originally signed by Boston as an international free agent in 2008. In 152 minor league appearances (91 starts)-all in the Red Sox organization-he is 44-33 with six saves and a 3.51 ERA (268 ER/688.0 IP).
