McGreevy's 51.8% ground-ball rate vs. Lauer's 24 home runs in 105.1 innings: St. Louis brings the sinker to a fly-ball park

BOTTOM LINE

Edge: McGreevy arrives at Dodger Stadium with a 3.66 away ERA in 2026 and a 51.8% ground-ball rate that runs counter to everything Lauer puts in the air. The Cardinals' right-hander has posted a 3.86 ERA overall this season, and his ability to keep the ball on the ground gives him a structural advantage against a Dodger lineup that generates plenty of fly balls.

Threat: The Dodgers' left-handed middle of the order points at McGreevy's weaker side. He has held right-handed batters to a .700 OPS in 2026, but left-handers reach him for .755, and six Dodger lefties cycle through that exposure all night. Freeman owns an .891 OPS against right-handers in 2026, and Tucker's career line against McGreevy -- 3-for-8 with no strikeouts -- says the contact comes easily. If the game tilts, it tilts through that group.

Watch: Ivan Herrera and Jordan Walker are the Cardinals' right-handed middle-of-the-order threats who carry the most weight against a left-handed starter. Herrera has posted a .592 OPS over his recent stretch and Walker a .802 OPS entering this series -- both are in extended slumps, and their ability to square up Lauer against the platoon advantage will determine whether St. Louis capitalizes on the handedness edge the matchup offers.

McGreevy vs. Dodger LHBs. McGreevy's 2026 split against left-handed batters sits at .263/.316/.439 (.755 OPS) across 370 batters faced -- his weaker side by a meaningful margin compared to his .700 OPS against right-handers. Six Dodger left-handed bats cycle through that exposure all night. Freeman is hitting .318 with an .891 OPS against right-handers across 386 PA in 2026. Tucker's 2026 mark against them is thinner: a .219 average and a .662 OPS over 371 PA. Freeman is the centerpiece threat against a right-hander with a soft split against left-handed batters.

Lauer vs. Cardinals RHBs. Lauer's 2026 split against right-handed batters is .241/.295/.460 (.755 OPS) over 342 batters faced -- better than the .852 OPS left-handers have posted against him, but seven Cardinals right-handers give St. Louis the volume to pressure that line. Ivan Herrera posted a .330 average against left-handed pitching over 124 PA in 2025, making him the Cardinals' most dangerous platoon bat in the matchup. The park works against St. Louis, though: the game is at Dodger Stadium, and Lauer's 2026 home ERA is 4.29 against 5.24 on the road. Tonight he pitches his better side, which narrows the Cardinals' window.

Jordan Walker vs. Lauer (career BvP). Walker has 1 hit in 2 career at-bats against Lauer, and that hit was a home run -- the only Cardinals batter with a power result in this BvP sample. The sample is too small to weight heavily, but in a lineup without many established BvP advantages against Lauer, Walker is the one name with a hard result on record.

Kyle Tucker vs. McGreevy (career BvP). Tucker is 3-for-8 (.375) in career plate appearances against McGreevy with zero strikeouts -- the Dodgers' most dangerous BvP entry against tonight's Cardinals starter. Tucker has not struck out in any of those 8 trips, which puts additional pressure on McGreevy to execute because Tucker is making contact against him consistently in a small but clean sample.

-- McGreevy TTO3 exposure. McGreevy has pitched into a third pass in 24 of 26 starts this season. If he reaches that stretch tonight, the Dodgers' lefty-heavy lineup faces a 2026 third-pass mark of .763 OPS-against across 121 batters faced -- nearly identical to his second-pass figure (.763), meaning the order does not get easier as the night wears on.

-- Lauer first-inning danger. If the Cardinals attack early, watch Lauer's first-pass numbers: he has posted a .906 OPS-against in TTO1 this season across 153 batters faced, driven by a .562 slugging mark and 10 home runs surrendered in that stretch alone. He settles considerably in the second pass (.708), so St. Louis's best window is the opening lineup turn.

-- Kyle Tucker stolen base threat. If Tucker reaches base, watch the running game: he is 9-for-9 stealing in 2026, a perfect mark, while Cardinals catcher Pages has thrown out 30.9% of baserunners this season on 55 attempts -- a workable rate but one that has not slowed aggressive runners.

-- Cardinals 6-9 lineup production. If the Cardinals trail late, watch whether the bottom of the order can generate a comeback: those slots have posted a .624 OPS since May 2, last in MLB. Against a left-hander the Cardinals cannot easily stack matchups around, the bottom third of the batting order is where the margin disappears.
