BOSTON -- The Red Sox are hopeful that setup man Joe Kelly will throw a bullpen session while the team is in Anaheim for a weekend series with the Angels.
Kelly was placed on the 10-day disabled list Saturday, retroactive to July 12, with a left hamstring strain.
Righty reliever Brandon Workman, who was recalled from Triple-A Pawtucket to replace Kelly, has impressed manager John Farrell. Workman entered play Thursday having made three relief appearances, allowing just one run and two hits in four innings.
"What we're seeing is a guy who may be understanding himself as a pitcher after going through what he has," Farrell said. "Now with the physical stuff returning, he's more advanced now than he's ever been."

Workman underwent Tommy John surgery in 2015.
Farrell says Workman's resurgence could allow him to work in more high-leverage spots if the bullpen situation demands it.
"The way Brandon Workman is throwing the ball now is equal to where he was pre-surgery," Farrell said. "If we're going to put Brandon Workman in and feel like he is pre-surgery levels, this is the guy who pitched the eighth inning of Game 6 of a World Series. I have never questioned his ability to challenge hitters."
Worth noting
• Farrell says that reliever Blaine Boyer will join the team in Anaheim and is due to get back on the mound in the next day or two. Boyer left Saturday's game against the Yankees after one inning due to forearm tightness and went on the DL.
• Shortstop Xander Bogaerts was back in Boston's starting lineup Thursday. He didn't start Tuesday or Wednesday while dealing with soreness in his right hand resulting from a hit-by-pitch July 6. Farrell says that Bogaerts isn't 100 percent, but is well enough to play.
