After the Marlins pulled out a 4-3 walk-off victory over the Rangers in 10 innings, McGehee sported a pine tar stain on his pants. Teammate Christian Yelich, who was fired up by the event, was given the split-in-half bat as a souvenir.
One of the veteran leaders on the youthful Marlins, McGehee regretted his actions.
"I really wish I wouldn't have done that," the 31-year-old third baseman said. "It's stupid. It's not the bat's fault."
McGehee was upset at himself because he struck out against Shawn Tolleson with two on in a tie game.
It's not the first time in his career that McGehee has split a bat over his knee. Actually, he did it last year in Japan when he was playing for the Rakuten Golden Eagles.
There have been a number of players through the years to break a bat over their knees. Jackson made the practice famous.
Looking at the big picture and the example that it sets, McGehee wishes he kept his emotions more under control.
