SAN FRANCISCO (CBS/AP) — San Francisco Giants first base coach Roberto Kelly has been taken to a hospital after getting hit in the back of the head when Buster Posey’s ball struck him while he was standing near second base during batting practice.

Kelly walked off the field with assistance Saturday afternoon and was placed on a stretcher to leave the ballpark. The Giants held a workout at AT&T Park a day before opening their NL championship series against the St. Louis Cardinals.

The 48-year-old Kelly has been the Giants’ first base coach since 2008. He played 14 seasons in the majors for eight teams and was a career .290 hitter with 124 home runs and 585 RBIs. The outfielder spent his longest stint with the New York Yankees, from 1987-92 and again in 2000.
