Kody Malstrom recommends betting under 0.5 runs in the first inning for the Cardinals vs Pirates game primarily based on the dominant performance of Paul Skenes. Entering his second season, Skenes continues his impressive form from last year's near-Cy Young campaign with an elite 1.46 ERA, 0.649 WHIP, and 1.46 FIP. His efficiency this season has been exceptional, averaging under one hit allowed per inning pitched while consistently striking out more than one batter per inning. Despite facing a formidable Cardinals offense ranked top-4 in hits, RBIs, total runs, and OBP, Skenes should be able to keep them quiet early. Additionally, the Cardinals lineup features a notable weak spot at the top of the order with Willson Contreras struggling badly, hitting just .105, increasing Skenes' odds of getting through the first inning without damage. On the other side, Sonny Gray, though carrying a high ERA of 5.73 due to early-season struggles, has managed a respectable WHIP of 1.000, suggesting poor luck rather than ineffectiveness. He faces a Pirates offense that struggles to consistently make contact at league-average rates, making it likely he also keeps them scoreless through the first.
