Rookie Austin Riley continued his hot major league start with a two-run homer and a go-ahead single in the 13th inning Thursday afternoon, allowing the Atlanta Braves to take three of four from the host San Francisco Giants with a 5-4 victory.
Riley's game-winning hit came after Dansby Swanson led off the 13th with a single off the Giants' seventh pitcher, right-hander Reyes Moronta (1-4).
Swanson stole second with one out, and was still there with two outs before Riley came through with his third RBI of the day and 12th in just nine games.
The 22-year-old former first-round pick also had a homer and three RBIs in Wednesday's 9-2 win.
