David Ross (concussion) is hopeful to begin a minor league rehab assignment Thursday with Double-A Portland.
Ross hasn't played since May 11 due to concussion-related symptoms. However, he has increased activity in recent days and could rejoin the Red Sox this weekend if all goes well.
Red Sox manager John Farrell said on WEEI in Boston that Shane Victorino (hamstring) is out of the lineup again Wednesday.
Victorino hasn't played since he left Monday's game with left hamstring tightness, but Farrell said he is "moving in the right direction." Consider him day-to-day.
Orioles acquired INF Josh Horton from the Athletics for a player to be named later or cash considerations.
Horton, 27, is a .274/.349/.369 hitter over parts of seven seasons in the minors. He'll function as organizational depth.
Brandon Belt is out of Wednesday's lineup due to back tightness.
It isn't a major concern, but Giants manager Bruce Bochy didn't want to take any chances. Consider him day-to-day for now. Brett Pill is filling in at first base Wednesday.
Rafael Betancourt (groin) will not require a trip to the disabled list.
Betancourt left Tuesday's game with a tight right groin, but it's merely some scar tissue from a previous injury. He was given anti-inflammatory medication and could be back in there as soon as Friday. Rex Brothers and Wilton Lopez could be in the mix for save chances until he's ready to go, but it doesn't sound like he'll have a lengthy absence.
Matt Joyce is not in Wednesday's lineup against the Blue Jays.
Joyce left Tuesday's game with right hamstring tightness, so it's not a surprise that he's not ready to play for the afternoon game. However, it's not known how much time he'll need to miss. Sean Rodriguez is playing right field Wednesday.
Pablo Sandoval is out of Wednesday's lineup against the Nationals due to illness.
Tuesday's hero should be back in there following Thursday's scheduled off-day. Joaquin Arias will make the start at the hot corner.
Jose Molina (hamstring) is back in Wednesday's lineup against the Blue Jays.
Molina hasn't played since Saturday due to a tight left hamstring. The Rays are hoping that the issue is behind him.
