Workman reports for short-term duty

HOUSTON -- Red Sox manager John Farrell might have some complicated juggling to do with his roster in the week ahead.

As Farrell hinted Sunday, pitcher Brandon Workman rejoined the team to temporarily take outfielder Daniel Nava’s place on the roster, while Nava is on three-day paternity leave.

Farrell said Nava’s daughter, Faith, was born Monday morning, and that Nava will return to the club Thursday in Kansas City.

Until then, Workman will serve as a reliever for the three-game series in Houston. Workman is available to pitch on Monday night, if needed.

Workman pitched six innings in a July 30 start against the Seattle Mariners to earn his first career win, but was moved to the bullpen after the Red Sox acquired starting pitcher Jake Peavy.

On Aug. 1, Workman was optioned to Triple-A Pawtucket.

By rule, a player must spend at least 10 days in the minors upon being optioned before being allowed to return to the majors, but Nava’s placement on paternity leave represents an exemption to the rule.

“He’s been impressive in the time that he’s been on the mound,” Farrell said of Workman. “Even when we asked him to make three starts, he was very effective for us. But given where we are, we need those contributions out of the bullpen.”

Farrell would not commit to using Workman strictly as a long reliever.

“We’ve had other young pitchers come up, and they’ve been pressed into pretty high-leverage situations,” Farrell said. “So depending on availability, we’ll see how that unfolds.”
