ST. LOUIS (AP) - Cardinals catcher Yadier Molina and most everyone else at Busch Stadium laughed at the bizarre sight - a ball somehow stuck to his chest protector , in plain view of everybody except him.
But the St. Louis star didn't think it was so funny when asked if a foreign substance helped the thing cling.
"Did I put anything on my chest protector to stick?" Molina said. "That's a dumb question."
Whatever happened, it sure made for strange situation at Busch Stadium. And it was the key play that sent the Chicago Cubs past St. Louis 6-4 Thursday.
The Cardinals led 4-2 in the seventh inning when things turned kooky.
Pinch hitter Matt Szczur led off by striking out on a pitch from Brett Cecil that skipped in the dirt. The ball bounced into Molina's protector and smack, it stayed there.
"I don't know if they've come out with Velcro on the protectors or it's just a fuzzy baseball," Cubs manager Joe Maddon said. "It was definitely Velcro-ed to his chest."
As Molina frantically looked for the ball, Szczur headed toward first base.
"I just took off running," Szczur said. "My first base coach told me it was stuck to his stomach. I thought, 'What?'"
By the time Molina looked down and discovered the ball, it was too late, Szczur was safe. The Gold Glove catcher could only smile and fans in sellout crowd roared - really, who'd ever seen such a thing?
"I haven't seen that one before," Cardinals manager Mike Matheny said. "I have no idea what happened there."
Catchers sometimes put pine tar somewhere on their uniforms, often around the shin guards, to help give them a better grip.
Molina was certain about one thing.
"That play changed everything," he said. "If we get that first out, everything changes."
Once Szczur reached on what was scored as a wild pitch, the Cardinals lost their grip on this game.
After a walk, Kyle Schwarber hit a go-ahead, three-run homer. The Cubs added another run later in the inning against Cecil (0-1).
Schwarber, who injured his knee in an outfield collision in the third game last year and missed the rest of the regular season, enjoyed the big hit.
"We celebrated, I made it past the third game this year," Schwarber said. "I turned the horseshoe around. I turned it up so I could make it through."
