The Detroit Tigers (4-4, 2-0 home, 4-4 O/U) host the St Louis Cardinals (4-4, 0-2 away, 4-4 O/U) at Comerica Park on Sunday Night Baseball, April 5. First pitch is slated for 7:20 pm ET on NBC/Peacock with Keider Montero (4.37 ERA, 1.39 WHIP in 2025) toeing the rubber for Detroit against Kyle Leahy (7.20, 2.00 WHIP in 5.0 IP) for St Louis.

The Tigers have dominated the first two games of the series, albeit in starkly different fashions, shutting out the Cards 4-0 on Friday before an offensive explosion in Saturday’s 11-6 win.

Below, I break down the latest lines, analyze the offensive advantages, and deliver actionable betting insights.

Cardinals vs Tigers Odds

Detroit enters as a modest -136 home favorite at FanDuel with St Louis a +120 underdog at bet365. On the runline, bettors must pay a steep premium of -185 to back St Louis with a 1.5-run cushion. A home victory of two or more runs offers an enticing +165 payout at BetMGM.

The total for this interleague clash is set at a flat 8.0 runs, with equal -110 juice on both sides at most sportsbooks.

Cardinals vs Tigers Picks & Predictions

The Tigers’ moneyline my primary target.

Pick #1: Detroit Tigers Moneyline (-122 at KALSHI)

St Louis has struggled mightily on the mound early in the 2026 campaign. Their pitching staff carries a bloated 5.18 team ERA, a 1.58 WHIP, and is allowing opponents to hit a comfortable .282.

Conversely, Detroit’s arms boast a 3.61 team ERA and a 1.28 WHIP while suppressing opposing lineups to a .221 batting average. Probable pitcher Keider Montero draws a highly favorable matchup against an offense slugging a collective .352 with a sluggish .651 OPS. Given these glaring pitching disparities, backing the home team to secure the outright win offers logical betting value.

Several Detroit hitters have also had considerable success against the active STL relievers (see Batter vs Pitcher section, below). Zach McKinstry has a 1.295 OPS in 11 plate appearances; Spencer Torkelson has a 1.811 OPS in 14 plate appearances; and Gleyber Torres has a 1.393 in 19 plate appearances. Parker Meadows is 4-for-4 with a HR.

STL vs DET Team Stats

Pick #2: Over 7.5 Runs (-102 at DraftKings)

When it comes to the total, the Over is my recommended play. St Louis has surrendered 5.37 RPG in their first two road games, and their bullpen sports an uninspiring 5.29 ERA.

Detroit’s lineup should find plenty of run-scoring opportunities to push this game past the projected total.

On the other side, Keider Montero is far from a shutdown starter. The Cards will scratch across a couple runs to help put the total to at least eight.

Batter vs Pitcher Stats

Monteiro has yet to take the mound this season. Leady was absolutely hammered in his first and only start, getting tagged for four runs on eight hits and two walks over 5.0 IP in a 4-2 loss to the Mets. He sports an abysmal 1.80 K/9 rate. His 5.39 xFIP confirms he yielded far too much quality contact.

The tables below set out the full history between (1) DET hitters vs Leahy, (2) DET hitters vs active STL relievers, (3) STL hitters vs Monteiro, and (4) STL hitters vs active DET relievers.

STL Cardinals vs DET Tigers Betting Splits

The MLB public betting splits for Cardinals/Tigers show heavy consensus. The betting public is highly confident in the home favorites. Currently, 80.8% of tickets are backing Detroit to win outright. More importantly, 66.6% of the total stake is also riding on them.

This heavy market alignment matches my primary betting recommendation. With St. Louis struggling on the road, backing the home team puts you on the same side as the majority of both the public tickets and the overall cash. However, I never justify a prediction solely on public splits; the pitching mismatch remains my primary angle.

The most lopsided betting action resides in the total-runs market. A staggering 91.2% of the tickets and 88.9% of the total money are hammering the Over. There is no sharp-vs-public divide here. The tickets and the money are moving in harmony, indicating a strong market consensus rather than a sharp syndicate attempting to fade public perception.

Cardinals vs Tigers Injury Reports

The most glaring offensive loss belongs to St. Louis, who will be without starting left fielder Lars Nootbaar for the foreseeable future. Transferred to the 60-day injured list, his absence is a devastating blow to a lineup batting an anemic .180 on the road.

For Detroit, the injury report is heavily tilted toward the mound. Former ace Justin Verlander is sidelined alongside multiple other starters. Despite this staggering volume of unavailable arms, their active staff has admirably managed the attrition. Manager AJ Hinch has more than enough offensive firepower to absorb these positional absences.
