With his glove and tickets on the first baseline, Cincinnati Reds fan Chris Smith thought his moment to catch a foul ball had arrived.
But as he prepared to catch Chris Heisley's pop-up, he felt something else in his glove: A shove from Cardinals' first baseman Matt Adams. Smith, who is recovering from knee surgery, fell backwards.
He then raised his middle finger in an angry gesture towards Adams.
MLB Commissioner Bud Selig's office is reviewing the play, but no official statement has been released about the incident yet.
More from the Cincinnati Enquirer:
"He gave me a shove and I fell back," Smith said. "I'm pretty sensitive about my knee right now. I'm fresh out of surgery, it's nothing to joke around about."
Leaning over the tarp, Adams was in position to catch the ball, but Smith had his glove above Adams' glove and made the catch. A fan has the right to catch a ball if he doesn't go into the field of play, and replays showed Smith didn't.
"I didn't reach over, I stayed where I was, I couldn't reach out if I tried, because I can't hit my knee on anything," Smith said, pointing to the cup holder in front of him right at knee-level.
