Reliever Aaron Heilman has been acquired by the Arizona Diamondbacks from the Chicago Cubs for two minor league prospects.
The 31-year-old former Mets right-hander was 4-4 with a 4.11 ERA in 70 appearances last season, striking out 65 and walking 34. He spent six seasons with the Mets before he was traded to Seattle in the J.J. Putz/Sean Green deal last December, then dealt to the Cubs a month later.
Chicago gets 24-year-old left-hander Scott Maine and 23-year-old infielder Ryne White. Maine was a combined 4-5 with seven saves and a 2.90 ERA with Double-A Mobile and Triple-A Reno last season. White hit .266 with 58 RBIs for Class A Visalia.
