Griff Tannen, AKA Tommy Wilson, is the grandson of Biff Tannen, and according to Dr. Emmett Brown, he has bionic implants, which give him enhanced strength and may or may not be legal in professional baseball. Tommy Wilson at baseball practice with Hill Valley High: Despite photographic evidence to the contrary, Tommy Wilson is not a hitter, but a big-bodied, right-handed pitcher the Mets drafted with their 19th pick in the 2018 draft. According to Amazin Avenue, he went to St. Mary's College after high school, but since he's a slacker, he didn't play any college ball til he transferred to Pierce College in 2017. After a successful season there, he transferred again to perennial powerhouse Cal State Fullerton, where he went 7-0 with a 2.71 ERA, striking out 81 hitters in 89.2 innings and eventually finding his way to the Mets! Great Scott! He has since taken his 93 MPH fastball to Brooklyn and has not yet allowed a run in 6.1 innings in 2018. He's walked 3 and K'd 6. He's 22 years old so hopefully a rapid rise is in his future. And if things get rocky, we already know his grandpa Biff stole the DeLoreon in 1985, so alternate time lines where young Griff becomes a Major League legend are very very plausible. Fun little extra tidbit- I am one of his 27 followers on YouTube, where he posts really cool drone vids that he's shot. If this baseball thing doesn't work out... qgolq9oS2ns
