Tauchman, 28, has just 69 MLB plate appearances under his belt despite a monster minor-league performance over the last two seasons. With AAA-Albuquerque in 2018, Tauchman slashed .323/.408/.571 with an outstanding 12.7% BB/14.9% K plate-discipline profile. ZiPS projects the lefty, who could see time at all three outfield spots for New York, to post a solid 96 wRC+/1.9 WAR season over 513 plate appearances in 2018.
Diehl, 24, moved to the bullpen full-time in the New York farm last season, to mostly excellent results. He didn’t crack the team’s top 30 prospects at either Baseball America or MLB.com, but if his 14.61 K/9 at high-A Tampa is any indication, the lefty’ll certainly be on the radar of the Rockies brass.
