Jerry Hairston, LF CIN
News: Reds SS Jerry Hairston, who left Sunday's game against the Brewers, has only a mild strain of his right hamstring, according to the Cincinnati Enquirer. He'll be re-evaluated Thursday.
Analysis: A lifetime .260 hitter in 11 major-league seasons, Hairston has been a surprise in his first year with the Reds. He hit .351 in 188 at-bats in the first half. The All-Star break will give him some time to heal, but hamstring injuries can be tricky for speedsters. Play it safe and reserve him for the shortened Fantasy Week 16 (July 17-20).
