Open Extended ReactionsPHOENIX -- San Diego Padres reliever Mason Miller was bringing the heat Tuesday night. Arizona Diamondbacks outfielder Lourdes Gurriel Jr. returned the favor. Gurriel crushed a 103.9 mph fastball from Miller into the left-field seats for a two-run homer in the eighth inning, tying the score at 5-all. It was the hardest-hit pitch for a homer since MLB started pitch tracking in 2008. He routinely throws over 100 mph and hit 104.2 mph with his fastest pitch Tuesday night.
