May at Home (3.24 ERA), But His TTO2 Cliff Is Cincinnati's Best Path Tonight

ARI  0 0 0 3 1 0 0 5 1 -- 10
STL  2 0 0 0 0 0 0 0 4 -- 6

Cardinals 6, Diamondbacks 10. STL grabbed a 2-0 lead in the first on a Walker RBI double and a Nootbaar RBI single, then watched Arizona flip the game with 4 runs in innings 4-5 -- headlined by Tyler Locklear's 2-run home run in the 4th off McGreevy. A 5-run Arizona 8th against Svanson and Graceffo (Locklear, Arenado, Moreno RBI singles; Carroll sac fly) put it out of reach. The Cardinals rallied for 4 in the 9th -- Torres 2-RBI single, Nootbaar 2-RBI single -- but came up short. Alec Burleson went 3-for-5; Nootbaar drove in 3.

BOTTOM LINE

Edge: Dustin May's home split is the statistical argument tonight. He carries a 3.24 ERA at Busch Stadium (75.0 IP) vs. 6.28 on the road (57.1 IP). The Cardinals are hosting a Reds team that ranks 5th in the NL Central, and May's home context -- against a Lowder with a 5.75 ERA and 1.64 WHIP -- is the clearest edge in this matchup.

Threat: Eugenio Suarez is 3-for-6 (.500 AVG, 1.000 SLG, 1 HR) in the career BvP sample against May. Nathaniel Lowe is 2-for-6 (.333 AVG, .833 SLG, 1 HR). Small samples, but both have hit May with power. Lowe also benefits from May's weaker 2025 LHB split -- .261 AVG, .852 OPS allowed vs. left-handed bats (334 PA).

Watch: May's second pass through the order is where this game gets decided. His 2025 TTO1 OPS allowed is .652 -- he is effective early. His TTO2 OPS jumps to .878 with 9 HR in 220 PA. If the Reds make contact into innings 4-6, the Cardinals' bullpen fork becomes the critical decision.

-- Crooks-May fresh battery. The catchers in May's historical data reflect his prior tenure -- none are on the Cardinals' active roster. Tonight's catcher, Jimmy Crooks, has 0 career innings paired with May in our sample -- a fresh battery. Watch for early pitch-selection calibration and pop-time sequencing in the first pass through the order.

-- Reds baserunning vs. Crooks. Dane Myers (18 SB, 78.3% success), TJ Friedl (12 SB, 80.0% success), and Ke'Bryan Hayes (12 SB, 80.0% success) are all active running threats. Crooks is catching in only his 14th game. An unfamiliar pop time is a live advantage for Cincinnati's baserunners tonight.

-- Svanson IR strand rate: 50.0%. Matt Svanson's 2025 inherited runner strand rate (50.0%, 26 IR) sits well below the league-average range of ~68-72%. He allowed 3 ER in 0.2 IP yesterday while inheriting runners. If he enters mid-inning with the game close, that 50.0% strand rate is the Cardinals' most exploitable bullpen vulnerability.

-- Walker K rate. Jordan Walker carries a 31.8% 2025 K rate vs. RHP (396 PA) -- the highest in the Cardinals projected lineup. Lowder's 18.2% K rate shows he challenges hitters. Walker is either a strikeout or a hard-contact threat in this matchup; his 31.8% K rate is the ceiling risk in the lineup's 4-hole.
