Kevin Kiermaier magically transformed Hyun Soo Kim's grand slam into a (very long) RBI single

It was the bottom of the seventh inning of Friday night's Rays-Orioles game, and Baltimore was down, 4-2. But the bases were loaded and Hyun Soo Kim was at the plate, ready to totally crush a Danny Farquhar fastball. And crush it he did -- but he forgot about Kevin Kiermaier.
Kiermaier has stolen more home runs than the Hamburglar has burgers. We're pretty sure that the first nine movies on the American Film Institute's "Top 10 Heist Movies" are just Kiermaier catches (No. 10 is "The Sting"). So we thought we knew how this story was going to end -- Kiermaier leaps into the air, snags the ball and Kim is out. Right? Well … almost:

Kiermaier just got there, but the ball bounced out of his glove. He was able to reign in a grand slam, but Kim also notched a very, very long single.
"I knew it was well hit. Most of the time, because I don't really have extra base hits, I thought the defenders would be way up in the front, so they'd have no chance," said Kim. "But Kiermaier was able to get the ball."
"I played center field for most of my career," said Michael Bourn, who was on second base when Kiermaier made his almost-catch. "So I know when somebody's going back and has a bead on it … so I saw the way he was running, he had a bead on it. It actually went into his glove, and I'm not going to say, the wall knocked it out, but when he stepped back, once he hit the wall and stepped back and took a couple more steps, it dropped out of his glove. Just by doing that, he saved two or three runs. That was a miraculous try, you've got to tip your cap to him, to get back and do that."
Kim's single scored a run, bringing the Orioles within one run of the Rays. After scoring two runs in the bottom of the eighth, they came back to win, 5-4.
