Michael McGreevy has made seven starts and logged nearly 40 innings in one month, and the Cardinals have every reason to treat that as a bright spot. His 2.52 ERA ranks 13th among qualified starters in all of baseball, a clean line that has stood out for a club in desperate need of quality pitching.
But the deeper numbers complicate the picture. Statcast puts McGreevy in the 10th percentile for expected ERA and gives him a 6.18 expected ERA, while also placing him in the bottom 10th percentile for expected batting average and expected slugging. That gap between results and underlying contact quality is the problem the Cardinals have to weigh now: the run prevention has been real, but the indicators behind it suggest the margin may be thin.
After one month of the season, McGreevy’s surface stats have made him look like part of the solution. The traditional line is the one that matters on a scoreboard, and for a rotation short on dependable innings, seven starts and nearly 40 frames are not easy to dismiss.
The tension is in whether those innings are built to hold. The Cardinals can point to the 2.52 ERA and the 13th-place ranking and argue that he has earned his place, but Statcast’s view says the contact he has allowed has not been nearly as clean as the results suggest. That leaves the organization with a familiar pitching question: trust the earned runs, or trust the process underneath them.
For now, McGreevy remains a useful answer to an immediate need. Whether he can keep being one for the rest of the season will depend on which version of his profile proves truer.
