ATLANTA -- The Giants will revive a little-known chapter of their city's baseball past by wearing replica uniforms of the 1946 San Francisco Sea Lions of the West Coast Negro Baseball League during Saturday night's game against the Braves.

The wardrobe change is part of the Braves' Heritage Weekend, which celebrates ongoing efforts to promote civil and human rights.

Fans watching on television must avoid confusion, since the Sea Lions' jersey sports a bear cub on its front. Research revealed that the Sea Lions purchased uniforms previously worn by the San Francisco Cubs, another semipro Negro League team. Thus, to preserve the integrity of history, the Giants designed their replica jerseys in similar fashion.

The Giants will donate one of their game-used uniforms to the Negro Leagues Baseball Museum in Kansas City, Mo.

Belt out of lineup against left-hander Minor

SF@COL: Belt gives Giants lead with two-run homer

ATLANTA -- The Giants have given fresh meaning to the term "balance of power."

Three different players entered May with at least six home runs: Brandon Belt (seven), Michael Morse and Buster Posey (six apiece). The Giants' pre-May slugging hasn't been that well-distributed since 1962, when they were led by Willie Mays (seven), Orlando Cepeda and Ed Bailey (six each).

Nevertheless, with left-hander Mike Minor starting for Atlanta, the left-handed-hitting Belt was out of Friday's lineup. Giants manager Bruce Bochy said that he explained the situation to Belt, who'll likely return to first base Saturday against Braves right-hander Julio Teheran.

Wanting right-handed bats against Minor, Bochy started Posey at first base and switch-hitting Hector Sanchez at catcher. Bochy noted that this would keep Posey's bat in the lineup while sparing him from the physical rigors of catching. Posey might benefit from this quasi-rest, since Bochy plans on starting him behind the plate Saturday and Sunday.

Cain throws, likely will start on Monday

SF@SD: Cain fans eight over seven terrific innings

ATLANTA -- Giants manager Bruce Bochy said Friday that he and the club's medical officials feel "optimistic" about Matt Cain making his next start Monday at Pittsburgh.

Cain accidentally cut the tip of his right index finger while attempting to pick up a knife and was scratched from his start last Tuesday against San Diego.

On Friday, Cain tested his arm -- and his finger, on which he wore a small protective device -- and felt fit after throwing.

Left-hander David Huff, who's recovering from a strained left quadriceps, also threw in the bullpen on Friday, simulating a 50-pitch effort. Huff said that he'll try to increase his workload to 65 pitches on Sunday. After that, the Giants' braintrust must decide when to send Huff on a Minor League injury rehabilitation assignment.

Huff's reinstatement from the disabled list will again force the Giants to decide whether they want to employ a 13-man pitching staff and try to survive with a bare minimum of four reserve position players. They opted for the extra pitcher and sent outfielder Juan Perez to Triple-A Fresno when Huff left the disabled list in mid-April.

"We have a little time to come up with that solution," Bochy said.
