Athletics first baseman Nick Kurtz exited Wednesday night's game against the Boston Red Sox with a bruised left forearm after being hit by a pitch. He was batting in the first inning with a 3-2 count when a 95 mph sinker from Red Sox starter Patrick Sandoval struck him.

Kurtz had just returned from the injured list Saturday after missing time with a right thumb sprain. The setback comes as the first baseman is enjoying a strong season, batting .260 with a team-leading 21 home runs.

He also ranks third in the majors with 77 walks, showcasing his plate discipline. The Athletics will monitor his condition closely given his recent injury history and importance to the lineup.
