Multiple fantasy outlets calling Montgomery a must-add with significant ceiling. Only actionable in 8–10 team leagues at 64% owned, but if he is somehow still on your wire in a shallow format, he should not be.

The walk-off was not a lucky swing — it was an opposite-field shot off a changeup from Raisel Iglesias, the exact type of contact that elite bat-to-ball hitters produce on off-speed pitches going the other way. Montgomery was the crown jewel of the Crochet trade and spent 2026 dominating Triple-A before the call. At roughly 28% owned he is available in the vast majority of leagues; that will change fast.

The debut was a spectacle, but the minor-league résumé is why you're actually adding him. He puts the ball in the air hard at an elite rate and takes walks — that's a middle-of-the-order profile once he settles in.

Montgomery was promoted June 9 and is getting everyday reps on the South Side while the White Sox build toward their future. He is a left-handed hitter with elite bat speed who projects as a 25-30 home run bat once he settles in — the pedigree is legitimate and the opportunity is real. His early sample is modest but he is getting the volume of plate appearances you need to develop at the major league level. At 18% owned the cost of a bench stash is low. Add now in 14-team leagues before his ownership catches up to the scouting consensus.
