Overview

• Gelof was hurt diving for a Bryan Reynolds grounder in the fifth inning at PNC Park and exited immediately during Oakland’s 4-3 win over the Pirates.
• X-rays confirmed a dislocation of his left shoulder, and the A’s are expected to place him on the 10-day injured list on Saturday with eight games remaining.
• Manager Mark Kotsay noted Gelof has dealt with a similar left-shoulder issue previously and praised the second baseman’s aggressive style of play.
• In 30 games this season, Gelof hit .174/.230/.272 with two home runs over 101 plate appearances, following his late July return and August recall from Triple-A.
• Darell Hernaiz is likely to handle most second-base duties going forward, and the club will assess the shoulder’s severity in the coming days to determine his spring outlook.
