The Chicago Cubs placed Geovany Soto on the 15-day disabled list, retroactive to May 17, and recalled right-handed pitcher Randy Wells from Triple-A Iowa.
Soto had arthroscopic surgery performed by Dr. Stephen Gryzlo on his left knee Friday after experiencing inflammation two days ago. He is batting .161 (15-for-93) with three home runs and six RBI in 28 games this season.
Wells, 29, returns for his second stint with the Cubs this season after going 0-1 with a 6.23 ERA (6 ER/8.2 IP) in two starts during his first stint from April 22-May 3. He is 2-2 with a 7.71 ERA (26 ER/30.1 IP) in six starts with Iowa this year.
The right-hander is 27-31 with a 4.05 ERA (229 ER/509.0 IP) in 88 major league appearances, all but four as a starter. Wells spent most of the last three seasons in the Cubs rotation, posting a 7-6 record with a 4.99 ERA (75 ER/135.1 IP) in 23 starts last year after missing nearly two months in April and May due to a right forearm strain. Wells went 6-3 with a 4.04 ERA in 14 starts after the All-Star Break.
