KANSAS CITY, Mo. — With Daniel Nava back from paternity leave, the Red Sox optioned righthander Steven Wright back to Triple A Pawtucket.
• Clay Buchholz had what John Farrell said was his most strenuous throwing from 90 feet. He is scheduled for 30-35 pitches in the bullpen Friday.
"He's making steady progress," Farrell said.
• LHP Franklin Morales, who threw an inning for Double A Portland Wednesday, could be activated off the disabled list as soon as Friday. He has been on the DL since June 23 with a strained pectoral muscle on his left side.
With Matt Thornton going on the DL on Wednesday, the Sox want that third lefty reliever.
"We've come to know that three lefties in the bullpen is a little bit of a luxury," Farrell said.
• RHP Alex Wilson had a setback with his sprained right thumb. He pitched in four rehab games for Pawtucket and is not scheduled for another outing.
"We've got to get that thoroughly checked again," Farrell said.
• Happy birthday to Craig Breslow, who turned 33 today.
• Junichi Tazawa was perfect for two innings Wednesday and in recent outings has shown the same command and velocity he did earlier in the season.
"There was a stretch where he was very conscious of not letting some fastballs leak back onto the plate," said Farrell. "A couple of righthanders had squared him up. Subconsciously he got into a little bit of cutting the baseball and it limited his velocity.
"I think he really felt like it was time to just cut the ball loose. He's been more aggressive; he's been more efficient. Last night was as probably as good as he's been all year. He's a key member of our bullpen. That ability to go against lefties and righties late in the game, control the running game, swing-and-miss ability. All that is key for us."
• Today is Day 9 of Will Middlebrooks and Xander Bogaerts Held Hostage as the Sox platoon Brock Holt and Brandon Snyder at third base.
So when will the Sox make a move?
"When one of the players mentioned steps up and says by his performance and his actions this is one that's going to make us the best team," Farrell said. "That's what is the bottom-line goal here, what is our best team.
"There might be some fluctuation with that. I'm not saying a move is imminent. That's the view that's taken with the four names that have been talked about at third base."
Bogaerts is hitting .275/.368/.462 at Pawtucket and played seven games at third base. Middlebrooks is hitting .259/.314/.459 at Pawtucket. Obviously he has more experience at third.
