The Cubs announced that they have claimed Guillermo Moscoso off of waivers from the Blue Jays. Right-handed pitcher Arodys Vizcaino, who is recovering from Tommy John surgery, was placed on the 60-day disabled list to make room for Moscoso on the 40-man roster.
The Blue Jays claimed Moscoso off of waivers just a week-and-a-half ago. Last season with the Rockies, the 29-year-old posted a 6.12 ERA with 8.5 K/9 and 3.4 BB/9 in 50 innings. He also started 21 games for the 2011 Athletics, posting a 3.38 ERA with 5.2 K/9 and 2.7 BB/9 in 128 innings.
