Ryan Perez might look back someday and say having Tommy John surgery on his right arm was the best thing that could have happened to his left.

That’s right, his left.

The 20-year-old from tiny Judson University in Illinois is one of baseball’s rare ambidextrous pitchers. He’s been all the rage in the prestigious Cape Cod League since he touched the low 90s on the radar gun — with both arms — in last week’s All-Star game.

He came on in the third inning and struck out the first batter left-handed, the second right-handed and the third left-handed.

“Didn’t see that coming,” Perez said.
