Zack Collins is a big leaguer.
Multiple reports indicated that Collins would be promoted ahead of Tuesday's Crosstown game against the Cubs, and that's exactly what the White Sox did, announcing the move Tuesday morning.
Additionally, the team placed Welington Castillo on the injured list with a strained left oblique. He left Sunday afternoon's game against the New York Yankees with what the team announced as lower back tightness.
While Rick Renteria has yet to speak on the matter, the catching situation figures to be not too dissimilar from what it's been, with James McCann getting the bulk of the playing time while appearing as the designated hitter on days when he doesn't catch. Collins will likely take over Castillo's catching duties and also see time as the DH.
Collins' arrival marks another step forward in Rick Hahn's rebuilding project. The 2016 first-round pick is ranked as the No. 11 prospect in the White Sox loaded farm system. Praised for his offensive abilities, Collins finished the 2018 season with a .382 on-base percentage and launched 15 homers at Double-A Birmingham. This season, he posted a .250/.374/.482 slash line with nine homers, nine doubles, 39 RBIs and 36 walks in 50 games at Triple-A Charlotte.
Adding another future piece to the mix at the major league level only makes the opening of the contention window in 2020 look more realistic, as Collins will join Eloy Jimenez, Yoan Moncada, Lucas Giolito, Tim Anderson and, eventually, Dylan Cease with a sizable amount of major league experience heading into that campaign.
Collins' promotion doesn't figure to be a temporary one that comes to an end once Castillo is healthy. Hahn and Renteria have spoken on multiple occasions about how they don't want to call these top prospects up and have to send them back down. It's happened before, of course, most recently with Carson Fulmer, the White Sox top pick in the draft before they selected Collins. But it's a road they'd rather not go down and an explanation they've given for keeping highly rated prospects such as Jimenez and Michael Kopech in the minors as long as they did.
There are questions about Collins' game, mostly on the defensive side of things. But the White Sox feel he's ready for his first taste of the major leagues, adding another piece of the rebuilding puzzle to the big league squad.
