The St. Louis Cardinals and Oakland Athletics wrap up their mid-May interleague series on May 14, 2026, at Sutter Health Park in West Sacramento. This matinee finale features a compelling mismatch on paper—a rising star for the Cardinals looking to continue his breakout campaign against an Athletics starter struggling to find his footing in the rotation.

The Pitching Matchup

The St. Louis Cardinals will hand the ball to right-hander Michael McGreevy. Through the first quarter of the 2026 season, McGreevy has been a revelation for the Redbirds, posting a 3-2 record with a superb 2.18 ERA. His command has been surgical, evidenced by a 0.86 WHIP that ranks among the best in the National League. McGreevy isn’t a prototypical flamethrower; instead, he relies on a sinker-heavy approach that induces weak contact and keeps the ball on the ground—an essential trait in the cozy dimensions of Sutter Health Park.

The Oakland Athletics counter with left-hander Jacob Lopez. While Lopez also holds a 3-2 record, his underlying metrics paint a more concerning picture. Carrying a 6.11 ERA and a 1.75 WHIP, Lopez has struggled significantly with his control, often finding himself in deep counts and high-leverage jams early in games. While he possesses the ability to miss bats, his tendency to surrender free passes and hard contact makes him a volatile option against a disciplined St. Louis lineup.

The Best Bets

The Safe Play: St. Louis Cardinals Moneyline (-135)

Despite being on the road, the Cardinals are the clear favorites for a reason. Michael McGreevy has been nearly twice as effective as Jacob Lopez this season in terms of run prevention and baserunner suppression. The Cardinals’ lineup, led by a surging Jordan Walker, has shown a particular affinity for left-handed pitching this year. At -135, you are getting one of the most consistent pitchers in baseball against one of the league’s most inconsistent, which is high-percentage value in any format.

The Value Play: St. Louis Cardinals -1.5 Run Line (+120)

If you believe in the McGreevy-Lopez disparity, the run line offers a much better payout. Five of the Cardinals’ last six wins have come by two runs or more, and given Lopez’s high WHIP, the St. Louis offense should have plenty of opportunities to build a cushion. The Athletics’ bullpen has also been taxed over the first two games of this series, potentially leaving the door open for late-inning insurance runs for the visitors.

The Prop Watch: Michael McGreevy Over 17.5 Outs Recorded

McGreevy is an efficiency specialist. Because he pitches to contact and keeps his walk rate low, he frequently cruises through innings with low pitch counts. He has completed at least six full innings in four of his last five starts. Against an Oakland offense that ranks in the bottom third of the league in team batting average, expect McGreevy to pitch deep into the seventh inning, clearing this mark with ease.

While the Athletics have shown grit at their temporary Sacramento home, the massive gap in starting pitching quality makes the Cardinals the definitive choice to take the series finale.
