The Cardinals were down basically to their last chance in the eighth inning Monday night, with redoubtable Cincinnati flame thrower Aroldis Chapman awaiting his turn in the ninth. But young outfielders Tommy Pham and Stephen Piscotty, performing like anything but rookies, came through late — just as they had come through early on Sunday.

After both had homered in the first inning the day before to spark a one-run victory in Chicago, Pham and Piscotty each delivered a key extra-base hit in the eighth Monday night as the Cardinals rallied for a 2-1 win over the Reds at Busch Stadium, their 12th triumph when trailing after seven innings. And Chapman was kept out of the game.

Cardinals manager Mike Matheny doesn’t want his hitters to fear any pitcher, but lefthander Chapman’s statistics over the last four seasons are almost too overwhelming to overlook. In those four seasons, from 2012-15, the Cardinals haven’t scored once off Chapman. They have had just seven hits in 83 at-bats (.084 average) with 42 strikeouts. This year, they are one for 22 with 13 strikeouts.

Pham knew of him. In his second big-league at-bat last season, in September, Pham was the game-ending strikeout by Chapman.

“I knew later and later, the possibility of him coming into the game was approaching,” Pham said. “If we could capitalize soon, it’s only going to help us.”

Matheny said, “You do keep in mind what their bullpen status is. And they’ve got a closer who’s done a nice job for a long time. We respect that.

“But I put our guys up against anybody, especially in tough situations because they seem to figure out a way to get it done. It was good overall effort of not giving in. How many times have we seen it this year? You just keep playing the game and trust that somebody’s going to get the job done.”

The Cardinals had been stymied for a second time this month by lefthanded rookie John Lamb, who, in two starts, has blanked them for 11 innings.

Finally, against righthander J.J. Hoover, Pham legged out a triple into the right-center-field gap to open the eighth. Pham has three triples, four homers and a double in his last six games.

Jhonny Peralta, gradually regaining his first-half stroke, smacked a game-tying single to right with one out. Piscotty then doubled off the left-center-field wall, chasing home from first Peter Bourjos — who was running for Peralta.
