Sandoval drops a spot in the lineup

SAN DIEGO -- Dropping third baseman Pablo Sandoval in the batting order proved to be easier said than done for manager Bruce Bochy, whose struggling third baseman descended all the way from third in the order to fourth for Friday night's series opener against the Padres. With Buster Posey and Michael Morse being rested, Bochy needed a formidable presence in the middle of the order. That turned out to be Sandoval, who is the only Giant besides right fielder Hunter Pence to start all 17 games. Sandoval hit third in each of his previous 16 starts except for April 3 at Arizona, where he batted cleanup.

After the Giants fell Thursday to the Los Angeles Dodgers, 2-1, Bochy mentioned the possibility of moving Sandoval to a lower spot in the order to relieve him of self-imposed pressure. Sandoval began Friday hitting .175 with two homers and six RBIs. That included a 1-for-11 tailspin with runners in scoring position.

Posey, Morse get a rest

SAN DIEGO -- Buster Posey and Michael Morse, two of the Giants' most prominent offensive threats, received rests Friday night and were not in the starting lineup against the San Diego Padres.

Neither player was hurt, though manager Bruce Bochy mentioned that Morse experienced some hamstring tightness Thursday. Both are expected to be in Saturday's lineup.

At this juncture, rest could be timely for both Posey and Morse. Entering Friday, Posey started 14 of San Francisco' first 16 games and was in a 1-for-19 skid, while Morse had started 15 games and was hitting .158 (3-for-19) with no extra-base hits in his past six games.

Their slumps haven't been all-encompassing. Posey's hitting .417 (5-for-12) with runners in scoring position. Morse owned a .306 batting average overall and was tied for the team lead with 10 RBIs.

Shortstop Brandon Crawford returned to the lineup after missing two games with tightness in his right hamstring.

Adrianza gets start at second

SAN DIEGO -- Ehire Adrianza, who went 3-for-3 off the bench Thursday against the Los Angeles Dodgers, started only his fourth game of the year, all at second base, in the Giants' series opener Friday night at San Diego.

Adrianza played shortstop almost exclusively during his eight professional seasons before this one. Nevertheless, said Giants manager Bruce Bochy, the 24-year-old rookie has adjusted smoothly to playing second.

"He has looked comfortable since Day One," Bochy said. "Going to his left or right, turning the pivot -- he has a lot of range, too."

Adrianza hadn't started a game since April 6 at Los Angeles.
