"It's just the decision they made, I guess," Pineiro said, although he admitted that some pain "is there; I'm not going to lie."
Pineiro said that he understood the circumstances. Team medical personnel did not expect him to be ready to pitch for a week. With the All-Star break looming, Pineiro will enjoy adequate time to rest without counting against the team's roster.
"I'm disappointed, but I understand," Pineiro said.
Crisp ailing: Everyday center fielder Coco Crisp, who entered the homestand as the team's hottest hitter but sat out for a second straight night with a sprained thumb, will not need time on the DL, manager Terry Francona said.
"Coco dove on his thumb the other day in Seattle," Francona said. "I don't think anybody, including myself, thought it would be any more than a day. It started becoming apparent that it was going to be more than a day."
The thumb was stiffer than expected on Friday. By Saturday, Crisp said, it was starting to feel better.
"Hopefully, in a couple of days I'll be fine," Crisp said. "Nothing major, which is cool."
Crisp said he congratulated Ellsbury from the trainer's table in the Red Sox clubhouse.
"We need somebody out there that can run the ball down [and he] has a lot of speed, is very fast and is a good outfielder," Crisp said. "He's a good player."
Clement throws: Matt Clement continued his year-long rehabilitation from arthroscopic shoulder surgery on Saturday, throwing a 25-pitch bullpen session at Fenway Park at 70-percent effort.
Francona and pitching coach John Farrell could not watch the session in person because they were planning roster changes.
"All the reports were good, [and] said he did very well," Francona said. "He threw with a fairly loose arm and comfort. Again, it's 70 percent, but he's come a long way. I'm really looking forward to actually watching him throw."
Donnelly progresses: Right-handed reliever Brendan Donnelly, whose setup role Pineiro briefly occupied, continued to progress from a forearm injury that landed him on the disabled list two weeks ago.
Donnelly threw on flat ground at different distance intervals, but the team will remain cautious with his progress.
"We're trying to get him to the point where -- because he's certainly not a finesse pitcher, he doesn't do anything finesse -- to where he doesn't feel it," Francona said. "And that's not easy with him because of the [violent] way he throws."
On deck: On Sunday, Julian Tavarez will get the nod against the Rangers at 2:05 p.m. ET. No American League team has hit the 15-year veteran harder in his career; Tavarez has a 6.20 career ERA against Texas. This will be the third time he has faced them this season, more than any other team. Kameron Loe, whose only start at Fenway Park resulted in seven shutout innings, will start for the Rangers.
