Roberts was called into Bruce Bochy's office and the manager explained to him that Rajai Davis deserved an extended look in center field.
"He told me to bear with him, that they need to see what (Davis) can do," Roberts said. "I understand it, but I know I've played well these last two months. I want to finish up well myself. When it comes down to it, I'll do what they tell me. That's the way I've always been."
Roberts, 35, has started just once in seven games since he banged his knee in a home-plate collision Aug. 9. He is expected to sit again today, Friday and Sunday when the Giants face left-handed pitchers.
General manager Brian Sabean said he appreciated Roberts' point of view, as well as Bochy's tough task of placating veterans while giving them less playing time.
"It will be difficult for Boch, but our job is to get some momentum going for next year," Sabean said. "Whether you're a young kid or a veteran under contract, now is the time to pick things up and show us what you can do."
Roberts missed a month because of elbow surgery, rushed his comeback and had a .211 average on June 30. But he was 2-for-2 with a pinch triple Wednesday and has a .339 average over his past 37 games, raising his season average to .269.
"It was a potentially lost year and he's turned it around," Sabean said. "It's a credit to the kind of professional he is.
Sabean said he is engaged in some trade possibilities. But Roberts will make $6.5 million in each of the next two seasons and would be difficult to move without the Giants eating a chunk of money.
Sabean said he still sees Roberts as a long-term fit.
"We hope so," he said. "Speed is a big component of today's game, especially in our league."
A day after Kevin Correia opened eyes in a spot start, Bochy said it's possible the club would employ a six-man rotation to finish the season. The move would lighten the load on young starters Tim Lincecum and Matt Cain. ... On the last day to sign players from the June draft, the Giants announced deals with first-round picks Madison Bumgarner (10th overall) and Wendell Fairley (29th overall).
