Herrmann appeared in 45 games with the Twins last season, serving as the primary backup for Kurt Suzuki. He hit just .146 over 113 at-bats and had just seven extra base hits, including two home runs. Minnesota selected Herrmann in the sixth round in 2009 and he batted just .181 over parts of four big league seasons.
It has been widely speculated that the Twins would look to improve depth at catcher this offseason and move past Herrmann, who now joins a Diamondbacks team that didn’t get much production from their catchers in 2015. The 27-year-old has also started 31 games in the outfield during his Major League career and played four innings at first base last season, meaning he can bring a flexible glove to the field in Arizona.
The Twins get Palka, a 24-year-old outfielder, in return. He was a third-round pick by the Diamondbacks in 2013 out of Georgia Tech and he finished last season ranked as the organization’s 29th-best prospect, according to MLB Pipeline.
He has slashed .274/.352/.504 over three minor league seasons and he’s been making strides every year. Palka spent all of last season with the Visalia Rawhide (A+), hitting .280 and with 29 home runs in 129 games. He is currently playing for the Salt River Rafters in the Arizona Fall League, where he is batting .304.
When he was drafted in 2013, Palka was just a first baseman, but he’s been converted to an outfielder over time, playing 88 games in corner outfield positions last season while appearing at first base only 33 times. Minnesota is currently very deep at first base throughout the organization so expect him to continue his work in the outfield.
