Freshman college baseball player hits 2 grand slams in first 2 at-bats of his career Posted Feb 22, 2021 Former MLB player Fernando Tatis made history in 1999 by hitting two grand slams in the same inning. He was the first MLB player to accomplish that feat. FAU freshman catcher Caleb Pendleton nearly duplicated Tatis’ night on Saturday; however, it’s even better. Pendleton hit 2 grand slams in the same inning in his first 2 at-bats of his college career. (Saturday Down South)
