MIAMI -- The Boston Red Sox acted to shore up their bullpen Tuesday, recalling relievers Ryan Cook and Tommy Layne.
Cook, acquired from Oakland for cash at the trading deadline, had been optioned to Pawtucket Aug. 4 but was eligible to return Tuesday because the Sox placed closer Koji Uehara on the DL with a fractured right wrist. Left-hander Layne returns after being optioned on July 30; he takes the place of Justin Masterson, who was designated for assignment on Sunday.
In another roster move, infielder Deven Marrero was optioned back to Pawtucket to make room for center-fielder Mookie Betts, who had missed the last 11 games with a concussion.
"We've got a couple of candidates to close," Red Sox manager John Farrell said. "Taz (Junichi Tazawa) would be one. Possibly (Jean) Machi. We'll get Ryan Cook's feet on the ground. We'll see where things go. We've got multiple options from what to choose from."
