Todd Frazier capped the most thrilling MLB Home Run Derby in recent memory by defeating Los Angeles Dodgers rookie Joc Pederson on Monday night. The Cincinnati Reds third baseman slugged 15 home runs in the final round to take home the victory.

Pederson hit first in the third and final round and it looked like he would be crowned the champion after impressively smashing 14 home runs. Frazier was tied with Pederson at 14 home runs after the initial four minute round concluded, before quickly hitting the walk off winner deep to left field on the first pitch in the 30 second bonus round.

Frazier advanced to the finals with a clutch performance late in the second round against Josh Donaldson. He hit two home runs in the final 15 seconds to win by a single home run.

MLB’s new timed system format was a huge success and it’s safe to say the league won’t be going back to the outs system any time soon.
