PHOENIX (AP) — The Arizona Diamondbacks have sent struggling right-hander Ian Kennedy to the San Diego Padres for left-handed reliever Joe Thatcher, a minor leaguer and a draft pick.

Kennedy, 21-4 two seasons ago, is 3-8 with a 5.23 ERA in 21 starts and hasn’t won a game in two months.

General manager Kevin Towers has said the team needed a situational left-hander in the bullpen and he got one in Thatcher, who is 3-1 with a 2.10 ERA in 50 games this season.

The Diamondbacks also got 23-year-old right-hander David Stites, who is 2-2 with a 2.08 ERA and 14 saves in 46 games with Double-A San Antonio.

Arizona has lost three straight and is 3½ games behind first-place Los Angeles in the NL West.
