Seth didn't mention anything about Romero's injury. From Sickels's writeup on Romero:
"Age 22; solid season in Double-A with 3.53 ERA, 120/45 K/BB in 125 innings, a mere four homers allowed; campaign ended on a down note with poor pitching in August (8.38 ERA) punctuated by a trip to the disabled list with a shoulder impingement; status unclear at the moment; when healthy combination of plus stuff and command could make him number three starter or impressive power reliever. ETA 2018 if healthy"
Romero's peripherals also point toward injury instead of tiring at the end of the season. He didn't strike out less that 22% of the batters he faced in any game for 2 straight months (averaging 28% overall), and then went 14%, 0%, two week break, 8%, 12%, shutdown for the year.
Does anyone have an update on his health?
