Hernandez was optioned to Triple-A Worcester on Saturday, Julian McWilliams of The Boston Globe reports.
EDGE Analysis
Hernandez had looked like he had a good shot to break camp in the big-league bullpen and was reportedly preparing to handle a multi-inning role. He'll instead head to the minors for now, presumably to work on his control. He's struck out 33.6 percent of opposing batters through 78.2 career major-league innings, but his 17.6 percent walk rate is far too high.
