Michael Mcgreevy Posts 2.52 ERA Despite 6.18 Expected Mark

Michael McGreevy has posted a 2.52 ERA through one month, and the Cardinals starter has done it in seven starts across nearly 40 innings. The surface line has him 13th among qualified starters in baseball, even as Statcast puts him at a 6.18 expected ERA.

McGreevy and the Cardinals

That gap is the story. McGreevy has been supplying elite run-suppressing innings for a Cardinals team in desperate need of quality pitching, which gives St. Louis a starter whose results have been far better than the underlying data.

Through the same stretch, Statcast has him in the 10th percentile for expected ERA, with expected batting average and expected slugging both sitting in the bottom 10th percentile. Those are not small misses around the edges; they point to a starter whose run prevention has held up even while the contact profile looks far less stable.

Statcast Profile

McGreevy’s 2.52 ERA is the clean number that jumps off the page. It has come over seven starts and nearly 40 innings, a workload that is enough to show a real pattern rather than a one-game spike.

The expected numbers complicate that picture. Statcast uses stadium-camera data and historical comparisons to MLB plays since 2015, and in McGreevy’s case the model paints a much rougher portrait than the box score does.

Run Prevention vs. Regression

For now, the Cardinals get the version that has been working: nearly 40 innings of low-scoring starts from a pitcher sitting 13th in all of baseball by ERA. The friction point is obvious, though, because his expected ERA and batted-ball indicators sit in the league’s basement.

That leaves McGreevy as one of the most interesting starters in the rotation picture. He has produced the results St. Louis needs, but the metrics say the margin for that success is thin.
