Guy Boston is leaning toward backing Steven Matz and the Cardinals at around even money (-102 to -105). Matz has pitched surprisingly well out of the bullpen to start the season and will be making his first start, making his innings somewhat uncertain. In contrast, he highlighted Ronel Blanco's struggles, especially pointing to Blanco's recent rough performance against a weak Minnesota offense. Although Houston boasts a stronger bullpen, he noted that key Astros relievers pitched yesterday, potentially limiting their availability. Additionally, Guy Boston emphasized trust in the Cardinals offense, mentioned their recent ability to put up substantial run totals (eight runs vs. Houston, seven vs. Philadelphia), and their respectable season average of 5.3 runs per game.

Kenny G shows skepticism about Steven Matz and the Cardinals bullpen start scenario as they host the Astros. Matz has struggled recently, highlighted by his last outing where he surrendered five hits and an earned run in just 2.1 innings against the Phillies. Matz, traditionally more of a bullpen arm, is being asked to initiate the game—a potential disadvantage against Houston. While the Astros lineup has suffered from inconsistency early, Kenny G notes improvement in Ronel Blanco's last outing (five innings, two runs, seven strikeouts vs Angels) and praises Houston's solid bullpen (3.08 ERA). Given Matz's erratic performances and Cardinals bullpen mediocrity (4.57 ERA), Kenny G leans away from the Cardinals, labeling their pitching setup risky against an improving Astros club.

The NBC Sports Bet Staff recommends caution betting on Steven Matz, highlighting his troubling performance trend. Matz has significantly struggled in his last 5 starts, posting an extremely high 8.74 ERA over that span. Despite a solid season ERA of 2.31, these recent performances suggest significant regression, making him a risky play. Facing a Houston Astros team fresh off their first shutout win of the season could further exacerbate these struggles.
