Giants' Michael Conforto leaves game with apparent leg issue

San Francisco left fielder Michael Conforto left Saturday's game against the visiting Cincinnati Reds in the fourth inning with an apparent right leg injury.

Conforto, who leads the Giants in home runs (7) and slugging percentage (.490), exited after making a hard turn at first base following a one-out single. He appeared to grab at the back of his right thigh before leaving the field.

Mike Yastrzemski came on to pinch run and stayed in the game in right field. Heliot Ramos moved from right field to left field.

In his second season with the Giants after seven with the New York Mets, the 31-year-old Conforto is hitting .280 with 20 RBIs after going 1-for-2 on Saturday. He is a career .254 hitter with 154 home runs and 474 RBIs.

His injury comes one day after center fielder Austin Slater left Friday's game in the second inning with concussion symptoms after hitting an outfield wall while trying to make a catch. Also, center fielder Jung Hoo Lee is listed as day to day with a foot injury.
