In the category of Best Performance by a Mississippian in the Majors, it’s hard to top a three-homer game. But Adam Frazier did it. The former Mississippi State standout hit his first career walk-off homer for Pittsburgh on Wednesday night, effectively stealing the thunder from former Bulldogs teammate Hunter Renfroe, who belted three homers for San Diego in a losing cause. Frazier’s two-run blast, with two outs in the ninth in a tie game, came off Milwaukee bullpen ace Corey Knebel and delivered a stern punch to the gut of a Brewers team seeking to tie Colorado for the second wild card spot in the National League. Frazier also had a two-run triple in the Pirates’ 6-4 victory. He is batting .282 with six homers in his second big league campaign. Renfroe, also in his second MLB tour, now has 24 homers this season. Both ex-Bulldogs were drafted in 2013, Renfroe in the first round, Frazier in the sixth.
