Ricky Romero underwent knee surgery this week. Romero, who's been bothered by knee issues since 2012, will be reevaluated after six weeks of prescribed rest. It's possible that he won't be able to throw another pitch this season. The right-hander had registered a 5.50 ERA over 37 2/3 innings at Triple-A Buffalo.
