SAN FRANCISCO -- After throwing a successful bullpen session Sunday, left-handed reliever Jeremy Affeldt seemed optimistic he'd be off the disabled list and back in the Giants bullpen sooner rather than later.

On Sunday, Affeldt threw a 30-pitch bullpen session, a few days following a 20-pitch session. Affeldt didn't throw breaking balls either time, but said he did spin a few curveballs from flat ground Sunday.

Affeldt (left oblique strain) said he has another bullpen session scheduled for Tuesday, where he would throw breaking balls and offspeed pitches, and said he should have a good gauge on when he'll return, which he hopes is the third week of August.

"I would assume that if everything continues, it'd be around then," Affeldt said. "It seems like that'd be a good target day. ... I think it all just depends."

Patient Burriss rewarded with callup

SAN FRANCISCO -- The last time Emmanuel Burriss said his fractured left foot felt 100 percent healthy, he reinjured it soon thereafter.

So, instead of putting a number on it, Burriss, who was recalled from Triple-A Fresno on Monday, simply said, "I feel good. ... I'll keep it at that."

To make room for Burriss, 25, the Giants designated right-hander Todd Wellemeyer for assignment.

It's been almost 14 months since Burriss played in his last Major League game on June 15, 2009. After being optioned to Fresno, Burriss fractured his foot in July before refracturing it in the first game of Spring Training this year.

Burriss said, "patience in this situation's definitely a virtue," but added he feels as though his speed hasn't declined, despite having spent much of the past year off his legs.

"I think my speed never really has been a problem, just more so the rustiness of ... my instincts," Burriss said. "My instincts [were] kind of off when I first started coming back and that's something that a speed guy needs to have, some instincts, and those are the things I was trying to regain."

Giants manager Bruce Bochy said Burriss would get an occasional start, but didn't yet have a plan. Between Fresno and Class A San Jose, Burriss was hitting .289 (57-for-197) with eight doubles, a triples and seven stolen bases.

Bochy downplays Sanchez's guarantee

SAN FRANCISCO -- A day after Jonathan Sanchez guaranteed a sweep of first-place San Diego -- whom the Giants don't play until Friday -- Giants manager Bruce Bochy said Monday he is focused on the current four-game series with the Cubs.

"That's between you all and Jonathan," Bochy said during his pregame media session. "[I don't know if] that comes with frustration with his start or what, but we're just concentrating on the Cubs."

After Sunday's outing, in which he lasted only four innings against the Braves, Sanchez -- who will start Friday's series opener against the Padres -- looked ahead to the weekend series between the top two teams in the National League West.

"We're going to play San Diego now and we're going to beat them three times," Sanchez said. "If we get to first place, we're not going to look back."

Sanchez also said the Giants now are a better club then the one that is 1-7 against the Padres, whom they haven't played since mid-May.

"That was a long time ago," said Sanchez of the record. "It doesn't matter. We have a better team now."

Bochy said he'd prefer to see confidence in his starting pitchers on the mound, adding with a smile, "I know the guys were giving him a hard time about it.

Giants drop Wellemeyer for infielder

SAN FRANCISCO -- After almost two months of rehab, it only took four batters and 17 pitches for Todd Wellemeyer to lose his spot in the Giants bullpen.

On Monday, the Giants designated Wellemeyer for assignment, recalling infielder Emmanuel Burriss from Triple-A Fresno, to put San Francisco back to a 12-man pitching staff.

Wellemeyer pitched only once out of the bullpen, allowing four straight hits while not recording an out Sunday. Looking back, Wellemeyer said, "I probably could've thrown all sliders and gotten out of there, but I had my starter's mentality."

Wellemeyer, who went on the disabled list with a right quad strain on June 11, was disappointed in the decision but said he understood the Giants needed another infielder. That was no more evident after Matt Cain pinch-hit for fellow starting pitcher Jonathan Sanchez on Sunday in the team's series finale against the Braves.

"I've seen enough and know the game enough to know we needed another infielder," Wellemeyer said. "[Infielder Juan Uribe]'s playing a ton, [second baseman Freddy Sanchez], he's battling every day. To get an extra guy off the bench -- especially in the situation they're in now -- will help the team."

Wellemeyer said he would accept an assignment to Triple-A Fresno if he cleared waivers and wasn't traded during the 10-day period. He also expressed a desire to pitch for a team in the midst of a playoff chase.

"If it's just to go to somebody else's bullpen, and not a contender, I'd rather stay here with the contender if I'm going to be in the bullpen regardless," Wellemeyer said when asked about being traded.

Worth noting

Giants infielder Eugenio Velez, who went on the 15-day disabled list with a concussion after being struck in the head by a foul ball on July 24, planned to take part in all baseball activities Monday and Tuesday then play games somewhere later this week. ... Freddy Sanchez (1-for-his-last-16) got the day off Monday but, despite the second baseman's recent struggles, Giants manager Bruce Bochy said Sanchez wouldn't be on the bench for more than a day or two.
