With the bases loaded, two outs and the Gateway Grizzlies down 3-0 in the second inning Sunday, Brandon Thomas stepped to the plate.
The outfielder for the Frontier League baseball club took a ball, then fouled off two more pitches working the count in favor of the pitcher 1-2.
Thomas then launched the next offering 394 feet over the fence and into the windshield of a truck parked considerably from the field -- his truck.
"Definitely worth it," Thomas, who ended up going 2-5 with four RBIs, tweeted after the game.
The grand slam opened up a faucet of scoring for the Grizzlies, who ended up beating the Joliet Slammers 17-6.
