2012 after an injury to his predecessor Matt Capps. He went on to finish the season 3–1 with 16 saves and a 2.56 ERA in 70 relief appearances. 2013 season Perkins was named to the American League All-Star team as an injury replacement. Despite the Twins' mediocre season, Perkins was 2–0 with 36 saves and a 2.30 ERA in 61 games. 2014 season On March 14, 2014, Perkins agreed to a four-year extension with the Twins worth a guaranteed $22.1 million. In July, he was named to his second All-Star game, where he was credited with the save for the American League in their 5–3 victory. He finished the season 4–3 with 34 saves and a 3.65 ERA in 63 relief appearances. 2015 season Perkins was an All-Star for the third straight year in 2015. He appeared in 60 games, going 3–5 with 32 saves and a 3.32 ERA, along with 54 strikeouts in 57 innings pitched. 2016 season After experiencing shoulder soreness at the beginning of the 2016 season, Perkins was placed on the DL after two appearances. On June 16, it was revealed Perkins would need season-ending surgery due to a torn labrum and damage to his rotator cuff. 2017 season After another injury-shortened season, Perkins' 2018 option was declined by the Twins with the expectation that the team would buy out his contract. He announced his retirement on January 23, 2018. Pitching style Perkins threw three pitches: a four-seam fastball (95–97 mph), a two-seam fastball (93–96), and a slider (83–86). There is little variation in his pitch usage against right-handed and left-handed hitters. His velocity and effectiveness have increased since the beginning of the 2011 season, coinciding with a move to the bullpen: "Going to the bullpen allowed me to get healthy. As a starter, I had just worn down." In 2009, as a starter, Perkins posted a 5.89 ERA and an average fastball speed of about 90 mph. His ERA dropped considerably in the bullpen (2.48 in 2011), and his strikeout rate nearly doubled. When Perkins was a starter, he also threw a curveball and changeup. Perkins's four-seamer has become a weapon, averaging almost 96 mph in 2011 and 2012. It also has a very high (for a fastball) whiff rate of 29% in 2012. Perkins claims to use PITCHf/x data and sabermetric statistics to study his pitching appearances. Broadcasting career On August 1, 2018, Perkins
