Cardinals Set to Unleash Top Prospect Michael McGreevy in Sunday Start vs. Dodgers
June just got a lot more interesting for the St. Louis Cardinals—and it’s not just because of their brutal schedule. With limited days off and a rotation in need of reinforcement, the Cardinals are gearing up to make a savvy move: calling up red-hot Triple-A pitcher Michael McGreevy for a spot start this Sunday against the powerhouse Los Angeles Dodgers.
And if that doesn’t get fans buzzing, it should.

The Cardinals have improved so much from the beginning of the season that they are now considers buyers rather than sellers as the trade deadline approaches.
The Rotation Crunch
St. Louis is heading into a grind of a month, where spacing out starters to keep them fresh could make all the difference. Earlier this year, the team shifted Steven Matz from the bullpen to the rotation to plug the gap—and it worked. But this time around, the team may have a new plan up its sleeve.
According to Katie Woo of The Athletic, the Cardinals are weighing a call-up for McGreevy as a temporary sixth starter to help them navigate the June gauntlet without overworking the current staff.
“McGreevy is 6-1 in 10 games for Triple-A Memphis this season with a 3.02 ERA and 54 strikeouts over 50 2/3 innings,” Woo reported. “He’s thrived in the spot start role before and wouldn’t be at risk developmentally.”
McGreevy Mania Incoming
That buzz got even louder Tuesday night when MLB.com’s John Denton all but confirmed what fans had hoped.
If it’s official—and all signs point that way. Thus, the highly touted pitching prospect would join the big club to pitch in one of the most high-profile matchups of the month. The Cardinals will move to a six-man rotation, giving the rest of the staff some time off while offering McGreevy a golden opportunity.
Why It Matters
Let’s be real—this isn’t just a patch job. McGreevy has earned this shot. He’s been dealing in Memphis, showing command, consistency, and growth which aligns with what the Cardinals are building for the future.
And the move has a double benefit: it allows the team to keep Matz in the bullpen, where he’s been effective in stabilizing a previously shaky relief corps.
It’s a low-risk, high-reward move indeed, and it keeps the Cards competitive in a month that could make or break their season.
Stay tuned, because if McGreevy shines on Sunday, the rookie might just pitch his way into something more than a one-time opportunity.
