The Braves signed Hamels, 36, to a one-year, $18 million deal this offseason. Their hope was he'd be a stable presence in the rotation, covering consistent innings and mentoring their younger pitchers.
But Hamels, who missed time last season with an oblique injury and endured shoulder fatigue in September, aggravated his shoulder during offseason weighted-ball exercises. He said he overdid it and added he isn’t concerned, according to general manager Alex Anthopoulos.
“He works extremely hard,” Anthopoulos said. “He cares. Sometimes you just end up doing a little too much and you end up flaring up.”
Braves position players report Monday, though most are already in camp. The team will hold its first full-squad workout on Tuesday.
