📣 DAD’S TAKEON TEFLON SERRANO
Look at this kid posing like he's some kind of supermodel instead of actually playing baseball. And "Teflon" Serrano? What, nothing sticks because you're too busy worrying about your hair to get dirty? Back in my day, pitchers didn't need a nickname – they just needed to throw strikes and keep their glove on the right way.
ABOUT TEFLON SERRANO
Teflon Serrano is a pitching prospect who came up through the Twins organization after signing as an international free agent back in 2015. He's worked his way through the minor league system pretty steadily, showing solid control and consistency at each level from rookie ball all the way up to Double-A Pensacola. The guy's posted respectable ERAs at every stop, usually hovering in that 2.70 to 3.71 range, which tells you he knows how to get outs. Since he doesn't have true rookie cards, you're looking at prospect and minor league issues here, so keep an eye out for autographs and low-numbered parallels if you want something that might have some pop down the road.
Serrano signed with the Twins as an international free agent in 2015. He made his professional debut in 2016 with the GCL Twins, posting a 2.45 ERA in 11 innings. In 2017, he pitched for the GCL Twins and Elizabethton, combining for a 2-1 record and 2.70 ERA in 16 appearances. Serrano spent 2018 with Cedar Rapids, going 5-4 with a 3.38 ERA in 26 games (11 starts). In 2019, he pitched for Fort Myers and Pensacola, posting a combined 8-7 record with a 3.71 ERA in 27 starts.
