Matt Wisler is a 27-year-old who began the year with the Cincinnati Reds. Before the season started, he was traded to the Padres. He pitched in 21 games out of the bullpen and posted a 5.28 ERA in 29 innings. On July 4th, he was purchased by the Mariners from the Padres. He finished the season with 23 appearances for the Mariners. In 22 1/3 innings, he posted a 6.04 ERA. In 51 1/3 total innings, he walked just 16 batters while striking out 63 batters.
Wisler was the 7th round draft pick of the San Diego Padres out of high school back in 2011. He became a Top 100 prospect nationally before the 2014 and 2015 seasons. He was traded to Atlanta at the start of the 2015 season in a package that sent Craig Kimbrel and Melvin Upton to the Padres.
Wisler made 19 starts in 2015 and 26 starts in 2016. Since then, he's mostly pitched out of the bullpen and struggled.
But there are reasons to like this claim. As Parker notes, he has become a slider pitcher.
Wisler is out of options, so should he remain on the Twins roster through spring training, he will need to remain on their 26-man roster or be put through waivers.
Earlier this week, the Twins announced that they had DFAd outfielders Ryan LaMarre and Ian Miller, and infielder Ronald Torreye.
