OAKLAND, Calif. -- Right-hander Clay Buchholz doesn't know when he'll be activated from the disabled list and rejoin the rotation, but he joined the Boston Red Sox on Friday in Oakland, one day after an encouraging rehab star for Triple-A Pawtucket.
"I haven't been told anything, but obviously this is where I want to be," Buchholz said before the Red Sox's game against the Oakland Athletics. "I want to be here battling with the guys and I feel like whenever I'm right mechanically and everything's tuned in, I give the team a chance to win when I'm on the mound. All the numbers that I had from this year, from the beginning of the year to my last start, I'm going to just forget about them. I'm starting over."
Buchholz went 2-4 with a 7.02 ERA in 10 starts before going on the disabled list with a hyperextended left knee on May 28. In his second rehab start Thursday, he allowed two hits, struck out five, walked two and threw 87 pitches over six shutout innings.
"I felt good," Buchholz said. "Everything was good. I was able to carry over some of the stuff I've been working on as far as delivery and mechanics. It worked out well. I was throwing strikes down in the zone and threw all my pitches. That's sort of what I got away from. That's where I wanted to get back to so I felt it was a good step in the right direction.
"I could have thrown 87 the first time out. That was one of the things that I wasn't having to battle with. It wasn't an arm fatigue or arm strength issue. They just wanted me to take my time, to take a couple starts to get up and down, up to five or six innings and I was able to do that yesterday."
Red Sox manager John Farrell said he won't make a decision about Buchholz until the end of his team's four-game series against Oakland on Sunday. John Lackey is slated to pitch Monday at Seattle and Jake Peavy on Tuesday. Farrell said Wednesday's starter is TBA with "multiple options" to consider.
"I think the most important thing is we're getting guys back to us that are healthy and we do have a couple of important decisions coming up," Farrell said.
• Jackie Bradley Jr. notched his eighth outfield assist Thursday night in the seventh inning when Oakland's speedy Coco Crisp was cut down at third base. He's tied for second in the major leagues, one behind A's left fielder Yoenis Cespedes.
The Red Sox rookie leads all major league center fielders in assists. He has the most assists by a Red Sox center fielder since Carl Everett (11) in 2000. Since 1954, only Ellis Burks (15 assists, 1987) and Fred Lynn (11 in 1975) had more assists from center field as rookies.
Bradley is batting just .205, but he said he hasn't let his troubles at the plate affect his defense.
"Two different sides of baseball," Bradley said. "You definitely got to be able to separate them. Me and [Shane] Victorino talk about it all the time. If I don't get hits that day, anybody who hits the ball out to me ain't going to get any hits, either. So that's the mindset you got to go into it with.
"You might not have a good day offensively at the plate, but as long as you can affect the game defensively to help out the team, you're helping."
Bradley went 1-for-2 and doubled off A's left-hander Scott Kazmir in Thursday night's 4-2 loss. That was his 13th double of the season and one of just five Red Sox hits in the game.
"I feel fine," Bradley said. "Just continuously working, trying to get better. I feel good right now. Like everyone says, when things are going good you don't really think about mechanics, and when things aren't going so well people are always trying to think about mechanics.
"It's not necessarily about that. It's about getting back to feeling good and seeing the ball and putting good swings on strikes."
• Outfielder Victorino was out of the lineup for the second straight day for Triple-A Pawtucket during his rehab assignment because of stiffness in his right hamstring and lower back.
"More treatment today," Farrell said. "We're going to get his activity built back up. Hopefully that's tomorrow but if not we'll go day to day with when he's next available. ... We feel that what he's dealing with is not going to keep him out too long. We'll get back out on the field and back to us as soon as we can."
• Outfielder Grady Sizemore, who was designated for assignment Tuesday, cleared waivers Friday, becoming a free agent. Sizemore hit just .216 with two home runs and 15 RBIs in 52 games with the Red Sox as he attempted to revive his injury-plagued career. He hit .133 in June. Now that he has cleared waivers, Sizemore could remain with the Red Sox at Triple-A, but he's free to sign with any team, and Farrell said it wouldn't surprise him if other teams were interested.
"He's a quality player that's still working his way back to regular play and normal strength," Farrell said.
