BOSTON -- The Red Sox made a number of roster moves Sunday, placing left fielder/catcher Blake Swihart (left ankle sprain) and catcher Ryan Hanigan (neck strain) on the disabled list and optioning reliever Noe Ramirez to Triple-A Pawtucket.
Swihart, a catcher by trade who has been playing the outfield of late, has what manager John Farrell termed a "pretty severe ankle sprain." Swihart exited Boston's win over Toronto on Saturday after running into a wall while chasing a foul ball in left field.
"He's going to be immobilized for two weeks," Farrell said, "and we'll reevaluate at that point to see what the next steps are."
Chris Young will start in left regularly, with Castillo serving as the fourth outfielder. This is Castillo's third stint in Boston this season. He played in only two major league games, and was hitting .245 with a .304 on-base percentage and .320 slugging mark with Pawtucket.
"We'll try to see if there's some spots where he ends up in the starting role, but the fact that he can play all three outfield positions defensively is certainly an asset in this case," Farrell said.
Hanigan, meanwhile, won't join the Red Sox on their road trip to San Francisco. After landing on the DL with a neck strain, Hanigan had an MRI that revealed inflammation in the area. He has been dealing with the neck issue for about a week and a half.
Hanigan will stay in Boston to receive treatment. Farrell did not detail any sort of timeline.
The light-hitting Leon doesn't bring much offensively, but his familiarity with the big league staff after spending much of last season in Boston is a benefit.
"Sandy's a guy that walks into our clubhouse with the comfort level of everyone on our staff and in our uniform," Farrell said. "We're fortunate to have a guy we can turn to in this case."
Those DL moves allowed the Red Sox to recall Hembree early. Normally when a player is demoted, as Hembree was earlier this week when the Red Sox activated Eduardo Rodriguez, he needs to spend at least 10 days in the minors.
Hembree owns a 2.14 ERA and 1.38 WHIP this season. He has pitched more than one inning in nine of his 12 games.
"When we had to make a move for Eddie, you send a pitcher out that's not necessarily doing something to be sent out," Farrell said. "He's pitched effectively for us, he's been very good against right-handed hitters particularly, so to have his fresh arm back in the bullpen -- much like Matt Barnes, the two-inning capability goes a long way with us."
