I came across this article that referenced thrown player equipment. Looks like Beltre was throwing in the towel and showed some frustration as his team was getting routed last night. Has anybody ever had this happen to them in a game?
Adrian Beltre was lined up right for Carlos Gonzalez, well off the third-base line, but CarGo sliced the ball perfectly down the line for an easy RBI. Beltre responded as any frustrated athlete or seven-year-old would do, and chucked his glove as hard as he could.
On the one hand, Beltre is lucky he didn't make contact, because hitting a ball with a thrown glove is an automatic triple and would've scored the runner from first -- per Rule 7.05 ©:
Three bases, if a fielder deliberately throws his glove at and touches a fair ball. The ball is in play and the batter may advance to home base at his peril.
