Bryce Harper might need an extra day or two Washington Nationals outfielder Bryce Harper is not convinced he can begin a rehab assignment as quickly as his manager believes. Davey Johnson had said Friday that he expects Harper to start a rehab stint Tuesday at Class-A Potomac. Harper, who has been sidelined since May 26 with left knee bursitis, said he thought he needed an extra day or two. "It just depends how I feel today and tomorrow," Harper said before Saturday's game against the Colorado Rockies. Monday is an off day, which is good. Tuesday, that's kind of early. I'm thinking Wednesday or Thursday, maybe. Reporters later informed Johnson of Harper's comments. "I'll have a conversation with him about that," Johnson said. When a player starts playing, it's really up to me, what I think they need. Not up to the player. Jose Bautista hit a tiebreaking home run in the eighth inning and the Toronto Blue Jays got their 10th consecutive win Saturday, beating the Baltimore Orioles, 4-2. Boston's Clay Buchholz is not expected to start Tuesday, and there's no timetable for when the unbeaten right-hander might be ready to return from a strained neck. Manager John Farrell says Buchholz (9-0) did not throw a bullpen session Saturday, although he did do some long-toss and flat-ground work. He's been on the disabled list since June 9. San Francisco Giants center fielder Angel Pagan will seek a second opinion from a specialist on his injured left hamstring, which he said sustained a small tear when he re-aggravated the leg during a rehab game with Class-A San Jose on Thursday night. Surgery remains an option, but the expected recovery time would be six to eight weeks. The St. Louis Cardinals optioned struggling left-hander Tyler Lyons, who lasted only 1 2/3 innings on Friday, to triple-A Memphis. ... Mets first baseman Lucas Duda returned to New York before Saturday's game against the Philadelphia Phillies to have an MRI on his left side.
