Elly De La Cruz delivered his first career walk-off hit in the 10th inning after Dane Myers hit a tying pinch-hit homer in the ninth, lifting the Cincinnati Reds past the St. Louis Cardinals 6-5 to split a doubleheader on Monday night.

Down to their final out in the ninth, the Reds turned to their bench, and Myers responded with his fifth home run of the season, belting it into the left-center seats to knot the game at 5-5. De La Cruz then sealed the win in the 10th, grounding a single into left field that deflected off third baseman Blaze Jordan's glove, allowing automatic runner Tyler Stephenson to score.

Emilio Pagán (5-1) pitched a hitless 10th for the win, while starter Rhett Lowder matched a career high with 6⅔ innings, allowing four runs on eight hits with five strikeouts. The Reds overcame a 4-1 deficit in the sixth, sparked by Michael Toglia's RBI double and rookie Héctor Rodríguez's first two major league RBIs.

St. Louis won the opener 2-1 behind strong pitching, but Cincinnati's late rally and clutch hits turned the tide. Justin Bruihl (0-1) was charged with the loss.
