The Cubs got right-handed pitchers Jake Arrieta and Pedro Strop as well as two international signing bonus slots from the Orioles in exchange for Feldman and catcher Steve Clevenger.
Feldman, on a one-year contract with the Cubs, went 7-6 with a 3.46 ERA in 15 starts this season. He is 46-50 with a 4.66 ERA in 219 major league games over nine seasons.
Arrieta is 20-25 with a 5.46 ERA over the last four seasons with Baltimore (2010-13). Strop was 5-2 with three saves, 24 holds and a 2.44 ERA last season as the primary setup man for the Orioles. He has battled a back strain this year, going 0-3 with a 7.25 ERA. Arrieta will be assigned to Triple-A Iowa, while Strop is expected to report to the Cubs later this week.
Guerrier is 25-33 with six saves and a 3.54 ERA over 10 seasons in the major leagues. He went 2-3 with a 4.80 ERA this season before being designated for assignment by the Dodgers on Sunday. The Cubs designated Marmol for assignment last week after he had gone 2-4 with two saves and a 5.86 ERA in 31 appearances, striking out 32 while walking 21 batters.
An All-Star as a setup man in 2008, Marmol’s best year as closer was 2010, when he had 38 saves in 43 chances along with 138 strikeouts and 52 walks. But fans had been booing him, and management was eager to cut a deal with the Dodgers, who also acquired an international signing bonus slot.
The Cubs also said they had acquired two international signing bonus slots from the Houston Astros for minor league infielder Ronald Torreyes, who batted .260 with two home runs and 25 RBIs in 64 games with Double-A Tennessee this season. He was originally acquired by the Cubs with left-handed pitcher Travis Wood and outfielder Dave Sappelt from Cincinnati for left-handed pitcher Sean Marshall in 2011.
