The moment - in retrospect - swung the game, a 6-4 Cubs victory, in Chicago's favor, primarily because Kyle Schwarber crushed a home run off Cecil two batters later, so it was certainly fresh on everyone's minds.
Harvey (1-0) walked off the mound to a standing ovation, far different from his previous appearance on July 4, when he was chased in the fourth inning and stared at the field from the dugout, a white towel draped over his left shoulder, a despondent look on his face (see full recap).
But Szczur's rally-starting strikeout was the play everyone wanted to talk about afterwards.
"There's a lot of lineups that are probably bunting right there with their leadoff guy, " Cubs right-hander John Lackey said.
But the St. Louis star didn't think it was so amusing when asked if a foreign substance helped the thing cling.
You've heard of the "hidden ball" trick in baseball? "I don't know how that happened", Molina said. That was certainly insane. "I've been playing baseball for a long time and I've never seen it, so I'm sure there is an uproar about it".
Cardinals reliever Brett Cecil threw a mistimed pitch that fell short of the plate to the Cubs' Matt Szczur early in the seventh inning. The reason Molina couldn't find the ball to put Szczur out at first?
The baseball bounced up and stuck to Molina's chest guard like Velcro as Szczur reached first base safely. "That's a dumb question", said Molina, who could not locate the ball as it clung to him, which helped set up Chicago's rally.
"I have no idea what happened. But you can't take away the home run". A play that was ruled an error by Ben Zobrist when he couldn't hang on to the ball on a potential double play helped open up the inning for the Cardinals, who took a 3-0 lead. Leake has won 10 or more games in four of the last six seasons.
Jay worked a walk and Schwarber delivered the game-changing blast.
St. Louis starter Lance Lynn went 5 1/3 innings in his first appearance since October 2, 2015.
Leaning on his fastball in a typical Lynn performance, the big righthander allowed five hits and two runs over 5 1/3 innings, walking one and fanning four.
That's a really good sign, I think.
Lackey was not flawless but if Zobrist would not have made that first inning error, his line would look much better.
Typically, recovering a swinging strike three in the dirt and making the play at first is something the all-time great Molina could do with his eyes closed. That was followed by RBI singles from Matt Adams and Randal Grichuk. The Cubs added another run later in the inning against Cecil (0-1).
Addison Russell's infield out in the sixth made it 4-2 St. Louis, and he added a second RBI grounder an inning later to cap the scoring.
NOTES: St. Louis LHP Tyler Lyons (right knee) will start a rehab assignment Friday night for Triple-A Memphis at New Orleans.
"You can't do much about it once it's over, " said Lackey (1-0), who allowed only one run and two hits in the rest of his six-inning stint and got 10 consecutive outs at one point.
