Castellanos Walk-Off Lifts Padres Past Cardinals in 10th as San Diego Salvages Series

The Padres scraped together a 3-2 victory over St. Louis on Sunday at Petco Park, but the path to that win revealed both their weaknesses and their capacity to escape when it matters most. Castellanos came off the bench in the bottom of the ninth trailing 2-0 with two outs and fell behind 0-2 before clawing back to a full count. Cardinals closer Riley O'Brien left a sinker middle-in, and Castellanos didn't miss—a two-run blast to left field that forced extras and kept the Padres alive.

The offense had limped through the four-game series, combining for just 14 hits, the fewest in any four-game stretch in franchise history. Tatis Jr., still without a homer 40 games into the season, came close again—a 105.4 mph line drive with a projected distance of 395 feet in the third that died in center field. He did contribute two walks, including a crucial one in the 10th after Jackson Merrill drew an intentional pass, setting the stage for Machado's game-winning sac fly.

On the mound, Walker Buehler continued his recent steady work, retiring 11 straight before surrendering an Alec Burleson single. The damage came via a mistake—a poorly placed 2-1 knuckle curve to Jordan Walker that sailed middle-in and cleared the Western Metal Building on the third deck for a two-run shot. Across his last six outings, Buehler has established himself as a reliable back-end starter, mostly avoiding the hard contact that plagued his first Padres appearances.

For bettors tracking San Diego's offensive momentum, Sunday's win arrived more through clutch-hitting than sustained production. The Padres' 14-hit weekend and extended drought from Tatis suggest continued vulnerability in team-total markets over the next stretch. However, their demonstrated ability to scratch out late-inning runs—Castellanos off the bench, Machado in the 10th—makes unders on their team total a sharper angle than laying heavy chalk on their overall run output. Look for San Diego team totals in the 3.5–4.0 range to offer value given their slap-hitting approach and reliance on splash moments rather than consistent run manufacturing.
