(AP) The Arizona Diamondbacks have traded left-hander Joe Saunders to the Baltimore Orioles for right-handed reliever Matt Lindstrom and cash considerations or a player to be named later.
Saunders, who was scheduled to start Sunday against San Diego, was 6-10 with a 4.22 ERA in 21 starts with Arizona this season. He won 12 games last season while helping the Diamondbacks win their first NL West title since 2007.
Lindstrom went 1-0 with a 2.72 ERA in 34 appearances with the Orioles this season. He has held right-handers to a .207 average and scoreless in 10 of his past 11 outings.
Lindstrom has played six major league seasons with Miami, Houston, Colorado and Baltimore.
To fill Lindstrom's place on the 25-man roster, the Orioles recalled right-hander Jake Arrieta from Triple-A Norfolk. Arrieta, Baltimore's opening day starter, went 3-9 with a 6.13 ERA in 18 starts with the Orioles before being optioned to Norfolk on July 5.
