Christian Oppor throws a bullpen in front of Blake Hickman

For the third time this month, a new description of Christian Oppor's improved breaking ball has dropped.

This one comes from Baseball America's Geoff Pontes, who led with Oppor in an article covering sleeper pitching prospects with impressive Stuff+ scores:

Christian Oppor, LHP, White Sox

  • Normalized Stuff+: 120

The 2025 season was a big one for Oppor, as the lefthander spent all of 2024 on the complex before making his full-season debut this year.

Oppor mixes three above-average pitches, per Stuff+. His four-seam fastball sits in the mid 90s, and he mixes a changeup with good velocity and vertical separation off the heater. Oppor’s low-80s sweeper registers the highest of any pitch in his arsenal and also boasts the highest whiff rate.
