Programming note: Braves-Giants coverage starts tonight at 7 p.m. on NBC Bay Area.
With the way rookie Chris Heston is pitching, it will be hard to bump him from the rotation when Matt Cain and/or Jake Peavy return to full health.
Just ask Mike Krukow.
"Well, it's a nice problem to have," the Giants broadcaster explained on KNBR 680-AM Friday morning. "Peavy's stuff his first three innings are fantastic. The problem he's having right now is pitching an inning, sitting down, getting back up, pitching another inning -- about three times of that, he starts to lock up. So that's a concern right now.
"If you think about what he's best suited for right now it's long relief, to where he has to go through the lineup one time. Now they have to fix that and he's working his tail off to get better. And once he can release that little grip in his hip that will allow him to get up and sit down six or seven times, you can get Peavy back. But right now they're not worried about that. They'll worry about that when he gets ready and when that problem goes away."
Peavy had a solid first rehab start for Triple-A San Jose on May 22, but he allowed six runs on nine hits during a Triple-A rehab assignment on Wednesday night.
Matt Cain is still working his way back from a flexor tendon strain and is hoping to return right before or after the All-Star break.

Although Heston is 5-3 with a 3.82 ERA, he may be the odd man out because he is the only one with minor league options remaining.
"If it comes down to it it's gonna be a very difficult decision, and you know they may even go to a six-man rotation," Krukow declared. "I mean you've got some age when you think about Hudson. I don't think you can think about Hudson as a 200-inning guy. I don't think they want to. I don't think they want to burn him out in the regular season should they get to a postseason environment.
"They want to keep him fresh. So you might even consider a six-man rotation."
Heston says he isn't thinking about what may happen down the road.
“You try not to let that stuff creep into your mind, as hard as it is. I mean, these guys are good. You try not to think about how it affects you. These guys are so good and any time they’re coming back, that’s huge for the team. I go out there when my name is called and give it my all.”
