Sean Zerillo’s Rockies vs Cardinals Preview

The Cardinals need young pitching, and Michael McGreevey is a useful back-end arm. He has a six-pitch arsenal with lackluster stuff (90 Stuff+) but excellent command (116 Location+, 3.7% BB). It’s been a limited sample, but I think he can be an effective pitch-to-contact guy.

Meanwhile, Rockies starter Austin Gomber has allowed a .958 OPS across 75 head-to-head plate appearances against the Cardinals. However, he’s recently introduced a new pitch mix, presenting a half-decent cutter in favor of his useless fastball. The change should help him produce better results in the short term.

The Cardinals rank second among MLB lineups in wRC+ against southpaws over the past month. However, I still project their current lineup for a 98 wRC+ against the side — I upgraded their lineup to a 107 wRC+ for Wednesday, and I still only project 8.11 runs for this total.

Meanwhile, there's no reason to be scared of Colorado's lineup, which ranks last in MLB in wRC+ against right-handed pitching (78).

Additionally, the Cardinals are off Thursday and can deploy their bullpen as needed.

Pick: Under 9 (-120 | Play to 8.5 -105)
