Romero (back) could soon play rehab games in the Florida Complex League, Ian Browne of MLB.com reports.

Romero has been sidelined all season due to a back issue, which Red Sox director of player development Brian Abraham described as lower back stiffness. "He is in a full baseball progression -- swinging/fielding daily in Fort Myers," Abraham said. "We are hopeful he will get in games later this month -- the FCL season starts June 5." Once Romero is ready, he'll head to Single-A Salem.
