Nationals' ​2017 first-round pick Seth Romero got off to a rough start. He was in hot water with Nationals general manager Mike Rizzo after violating curfew several times. He then cleaned up his off-field act and began to pitch well in Single-A ball. 

Unfortunately for Romero and the ​Nationals, his progress will have to be put on hold. 

This one really hurts. Romero pitched 25.1 innings for Single-A Hagerstown and struck out 34 batters. He showed them the big-league ready stuff they felt he had. 

Now, Romero will be a year behind schedule. 

The ​Nationals have had several pitchers fall victim to Tommy John surgery, most notably Stephen Strasburg.

It's just unfortunate that a guy who's always delivered on the field but struggled off it now gets hurt. This comes after Romero seemed to have learned something about his off-field antics.
