The strange play occurred in the eighth inning when, with a runner on first, Athletics shortstop Cliff Pennington bunted toward third base. Jose Lopez attempted to field the ball with his bare hand, but the ball went off his hand and close to the third-base line.
Moore was moving up the line toward third base, and attempted to scoop the ball up with his mask.
The umpiring crew huddled for several minutes and advanced both runners one base. According to the rule, Pennington was credited with a double.
