Hunter Renfroe announced his presence with authority for San Diego on Thursday night. In his first at-bat since coming off the disabled list, the former Mississippi State star from Crystal Springs hit a home run at San Francisco. Renfroe’s 17th homer, which came off Madison Bumgarner no less, moves the rookie slugger into a tie with Meridian Community College alum Corey Dickerson for the lead in the All-Mississippi Home Run Derby. Renfroe, who was on the 10-day DL with a neck problem, had not homered since June 29. All-Star Dickerson, who has been fighting a slump, last went deep on June 24 for Tampa Bay. The home run race has tightened up during that time. Ex-Southern Miss star Brian Dozier now has 15, MSU product Mitch Moreland 12 and former Ole Miss standouts Zack Cozart and Seth Smith 11 each. Renfroe, described by cbssports.com as a “low-end fantasy asset,” is hitting just .231 but has 41 RBIs and 35 runs in 86 games. Dozier is the top RBI man among state players with 47. Dickerson has 42, as does Moreland. P.S. USM product Taylor Braley made his pro debut Thursday, pitching a scoreless inning for the Gulf Coast League Marlins. Braley, a two-way star for the Golden Eagles, was drafted as a pitcher in the sixth round by Miami last month. Also appearing in that rookie league game for the Marlins was Blake Anderson, the converted catcher out of West Lauderdale High who has now worked two innings as a pitcher (see previous post).
