The Cubs sent right-hander Scott Feldman and catcher/infielder Steve Clevenger to the Orioles in exchange for right-handers Jake Arrieta and Pedro Strop and international-signing money. The news was first reported by Keith Law on Tuesday afternoon.
Feldman, 30, is 7-6 with a 3.46 ERA and 1.143 WHIP in 15 starts with the Cubs this season. He had signed a one-year, $7 million contract as a free agent with the Cubs last November after spending the first eight seasons of his career with the Rangers.
Clevenger, 27, went 1-for-8 with the Cubs after hitting .327/.426/.596 in 15 games for Triple-A Iowa.
Orioles general manager Dan Duquette commented on the team's new additions in a statement:
"Feldman is a proven starter with postseason experience who should help stabilize our rotation for the second half... Clevenger is a left-handed bat with good receiving ability. He could also make a contribution to this year's team."
Arrieta, 27, started five games for the Orioles this season and was 1-2 with a 7.23 ERA and 1.775 WHIP. Strop, also 27, has a 7.25 ERA and 1.701 WHIP in 29 relief appearances for the Orioles.
