Coors Field and Hunter Renfroe. Sounds like a potentially explosive combination, and on Friday night it most definitely was. Renfroe, the so-called “country strong” slugger from Crystal Springs, blasted three home runs for San Diego, helping the Padres pull off a crazy rally and beat Colorado 16-12 in 12 innings. Renfroe, who now has 21 bombs on the year, hit a solo homer in the second inning, a two-run shot in the ninth as part of a six-run eruption and then added another two-run blast in the 12th. The former Mississippi State star went 4-for-7, lifting his average to .253, and his five RBIs gives him 40 for the season. He has seven homers in his last 15 games. Eight Padres have hit three homers in a game in the franchise’s 50-year history, and Renfroe, in just his fourth MLB season, has done it twice. And to think, his name is being mentioned in trade rumors.
