White Sox's Zack Collins: Makes strides defensively

Collins finished the 2017 at Double-A Birmingham, posting an .893 OPS over 12 games with the Barons.

Collins came out of college with a reputation as a sure-thing bat with questions surrounding his defense -- however, his season played out the opposite way. He batted just .224 while striking out 27.3 percent of the time over his 471 plate appearances. It's not uncommon for young catchers to experience an initial dip in offense as they learn the defensive aspects of such a demanding position at the professional level. One noteworthy item that stands out is Collins walked in 18.5 percent of his plate appearances to post a .370 on-base percentage. There's nobody blocking him at the major-league level, so Collins could reach Chicago as a regular by 2019 if his defense remains on the same trajectory.
