When the remainder of his teammates made their way from the dugout to the clubhouse after Monday’s season opener, Adam Wainwright was there to shake hands, exchange congratulations and hear one teammate’s version of the final score.

“Yadi wins,” someone, possibly quipster Matt Holliday, said.

The defending National League champions opened the regular season with a 1-0 victory against the rival Cincinnati Reds at Great American Ball Park, and history will show that Molina provided the game’s only run with a homer in the seventh inning. The box score has a gift for understatement. Molina smoothed the ragged edges of an opening day that showed how resourceful the Cardinals can be, if not how sharp they intend to be this season.

Molina turned a ball spinning foul into a double play that saved Wainwright from trouble. He shepherded the Cardinals’ young flamethrowers through a complex eighth inning that threatened the Cardinals’ lead, and he scarred Reds starter Johnny Cueto’s otherwise dominant day. A crowd of 43,134, the second-largest ever at GABP and many of whom booed cherished villain Molina at every turn, may remember the score the way the Cardinals did: Yadi 1, Reds 0.

“His game today,” Wainwright said. “And I was lucky to be a part of it.”

Wainwright claimed the first opening day win of his career with seven shutout innings and nine strikeouts, and the righty became the 13th pitcher in club history to reach 100 wins. Trevor Rosenthal pitched a perfect ninth for his fourth career regular-season save. What happened in between decided the game.

In the eighth inning, the Cardinals mangled two routine double plays and committed two errors. For the first time the Reds had a runner safely reach third base when a grounder skipped between rookie Kolten Wong’s legs. That put the tying run at third and another Red at first with no outs. Lefty Kevin Siegrist didn’t get a call on a 97 mph fastball that teased the strike zone, but he did get Jay Bruce to bounce into a grounder that the Cardinals used to tag out the lead runner, Brandon Phillips.
