Vosler hit 11 homers in three seasons at Northeastern and 14 in his first three years as a pro after signing for $80,000 as a 16th-rounder in 2014. After making changes to his left-handed swing under the tutelage of Minor League hitting coaches Andy Haines and Jacob Cruz, he finished second in the Double-A Southern League with 21 homers and 81 RBIs in 2017.
Early in his pro career, Vosler made an effort to hit fewer ground balls and succeeded, albeit by developing a pronounced uppercut. He had more success last year, when he took a more direct path to the ball and focused more on creating backspin. His strikeout rate rose to a career high 23 percent and he doesn't hit for a high average, though he draws enough walks and gets hit by enough pitches (an SL-leading 20 in 2017) to post healthy on-base percentages.
Vosler's below-average speed and quickness limit his range at third base, but he gets the job done there with reliable hands and solid arm strength. He's not going to dislodge Kris Bryant from third base in the big leagues, so the Cubs have tried to enhance his versatility. He played extensively at first base in the Arizona Fall League and can fill in at both middle-infield spots.
