He made his MLB debut that day, pitching in relief, walking two batters and hitting another in the ninth inning. Vizcaíno earned his first MLB win in the Braves' 2-1 extra-inning victory over the San Francisco Giants on August 16. In seventeen games with the Atlanta Braves, Vizcaíno had a 1-1 record, 4.67 ERA and 17 strikeouts in innings. After the 2011 season, Baseball America rated Vizcaino as the Braves' second best prospect, after only Julio Teherán. On March 20, 2012, Vizcaino underwent Tommy John surgery causing him to miss the rest of the 2012 season. Chicago Cubs (2012–14) On July 30, 2012, Vizcaíno was traded along with right-handed pitcher Jaye Chapman to the Chicago Cubs for left-handed pitcher Paul Maholm and outfielder Reed Johnson. Vizcaíno started the 2013 season on the 60-day disabled list still recovering from the Tommy John surgery he previously had and was expected to return after the All-Star break.
