Joshua Baez may emerge as a star in MLB very quickly if he keeps this pace, which obviosuly he’s not going to hit a home run in every at-bats (maybe he actually will…), but with the impact he could have on the current Cardinals roster.
MLBTR.com’s Darragh McDonald wrote (about the Joshua Baez promotion):
“Despite the concerns, Báez is still considered a top 100 prospect by some. Baseball America currently lists him #56 overall and MLB Pipeline has him at #59. Kiley McDaniel of ESPN had Báez #93 coming into the season. Some are less optimistic, however. Keith Law of The Athletic didn’t have Báez top 100 before the season and recently provided an updated top 70 with no Báez on it. FanGraphs currently lists him sixth in the Cardinals’ system and outside the Top 100.”
MiLB.com lists Joshua Baez as the Cardinals No. 3 overall prospect.
Over 103 games in AAA this season, Baez was batting .256 with 34 home runs, 22 doubles, and an OPS of .901.
