Keyed by Matt Holliday’s grand slam, the Cardinals scored seven runs in the top of the 10th inning and surged for an 11-4 victory against Cincinnati at Great American Ball Park.

The overture of offense turned a close game into a thunderous rout for the Cardinals and a series win.

Holliday welcomed rookie Curtis Partch to the majors when he took the young righty’s sixth pitch of his debut and sent it an estimated 460 feet into the second deck beyond left field. Daniel Descalso’s RBI double started the scoring and broke a 4-4 tie.

The team with the best record in baseball became the last to win a game in extra innings. The Cardinals had lost their previous four extra-inning games.

The win restored the Cardinals’ lead in the National League Central to a season-high four games. Their first visit to Cincinnati this season ended like the previous series between the two rivals at Busch Stadium this season – with the Cardinals taking two of three. The Cardinals are unbeaten in their previous 13 seasons as they head to New York for a three-game stay that begins Tuesday at Citi Field.

Twice in the first seven innings the Cardinals rallied from two-run deficits. They did not take a lad in the game until the 10th inning when Descalso’s RBI double ricocheted off the left-field wall. Matt Carpenter added a two-run single and helped set the stage for Holliday’s clout. The grand slam was the fifth of Holliday’s career. Trevor Rosenthal earned the win by pitching two scoreless innings with four strikeouts. He matched Reds’ closer Aroldis Chapman heat for heat as the Cardinals rookie repeatedly fired 98-mph to retire all six batters he faced.

Rosenthal pitched two scoreless innings and received his first big-league victory. Chapman pitched only one before having to be lifted for a pinch hitter.
