The St. Louis Cardinals welcome the Colorado Rockies to Busch Stadium on Sunday, August 9, for a 2:15 PM ET first pitch. Michael McGreevy gets the ball for St. Louis, squaring off against right-hander Michael Lorenzen on the Colorado side. With the regular season deep into its second half, every game at home carries weight — and this one gives manager Oliver Marmol's club a chance to build on whatever momentum they carried into the weekend against a Rockies squad that has made pitching through their lineup a manageable assignment for much of 2026.

Starting Pitching Matchup: McGreevy vs. Lorenzen

McGreevy is the story here for Cardinals fans. The young right-hander has been one of the more intriguing arms in St. Louis this season, and Sunday is another opportunity to show he belongs in a meaningful rotation spot. The Cardinals will need him to work deep into the game and limit the free passes — Colorado's lineup can do damage when pitchers fall behind in counts.

Lorenzen is a veteran with plenty of big-league experience, capable of mixing his arsenal effectively. He's not a pitcher St. Louis should take lightly, but Busch Stadium's dimensions and a Cardinals lineup with multiple right-on-right matchup questions for Lorenzen make this a winnable afternoon for the home side.

Cardinals Lineup to Watch

• JJ Wetherholt (2B, leadoff): The young second baseman sets the table. His ability to get on base early is critical to this offense generating pressure.
• Iván Herrera (DH, 2nd): Herrera in the two-hole signals the Cardinals want a bat with on-base ability right behind Wetherholt to create early-inning traffic.
• Alec Burleson (1B, 3rd): Burleson has shown the ability to do damage in the middle of the order. He'll see some key run-producing opportunities with runners on base.
• Jordan Walker (RF, cleanup): Walker hitting fourth puts the spotlight squarely on him. This is the role St. Louis envisioned for the former top prospect — producing in the heart of the lineup.
• Masyn Winn (SS, 6th): Winn's defense alone is worth the price of admission, but his bat in the lower third of the order provides a threat that prevents opposing pitchers from relaxing.

Rockies Lineup Keys

Colorado sends out a lineup that includes Hunter Goodman in the cleanup spot and Ezequiel Tovar hitting ninth — an unusual placement for a shortstop with Tovar's offensive capability. Jake McCarthy leads off, and Cole Carrigg bats second in center field. The Rockies will lean on Willi Castro and Kyle Karros in the middle of the lineup to provide any damage against McGreevy. Brett Sullivan catches for Colorado.

Keys to the Game

• McGreevy's command: If he throws strikes early and avoids long at-bats, St. Louis controls this game.
• Walker's production: The cleanup spot demands run production — a big afternoon from the young outfielder could be the difference.
• Busch Stadium crowd: A Sunday afternoon home game is exactly the environment where this Cardinals club needs to take care of business.

Prediction

This is a game St. Louis should win at home. McGreevy has the stuff to navigate Colorado's lineup, and the Cardinals' lineup — from Wetherholt at the top to Walker in the four-hole — has enough firepower to get to Lorenzen early. Cardinals win, 5–3.
