Tigers promote prospects Bryce Rainer, Jordan Yost in minor leagues

Both players are left-handed-hitting shortstops.

Rainer ranks as the Tigers' No. 3 prospect, according to MLB Pipeline. He trails only shortstop Kevin McGonigle (No. 1) and center fielder Max Clark (No. 2) on the top-30 list.

Yost ranks as the No. 9 prospect in the organization.

In 2026, Rainer hit .167 with one home run, six walks and 20 strikeouts in 11 games for Low-A Lakeland. He hits the ball hard, but he struggled with a terrible 40.8% strikeout rate, possibly because of a leg kick and excess hand movement as part of an awkward-looking swing.

His swing mechanics changed drastically from 2025 to 2026.
