LOS ANGELES -- From the Giants' perspective, the infield might as well be composed of thin ice, not dirt.
Ehire Adrianza was diagnosed Friday with a broken left foot that will sideline him for 6-8 weeks, leaving Kelby Tomlinson as the lone extra infielder. That's because San Francisco, which had no other infielders on the 40-man roster, recalled outfielder Mac Williamson from Triple-A Sacramento to fill the roster vacancy.
Tomlinson started at shortstop in Friday night's series opener against the Dodgers, largely since the presence of left-hander Clayton Kershaw forced Brandon Crawford to the bench. Crawford reported that his sore left hip flexor, which forced him to leave Thursday's finale at Colorado prematurely, was much improved. Manager Bruce Bochy said that Crawford would be available off the bench.

To insure that the Giants receive adequate infield coverage, Bochy said that catcher Trevor Brown could play first or second base, and Matt Duffy, the everyday third baseman, could play shortstop if needed. Those are all options aside from playing Buster Posey at first base and using Tomlinson everywhere else.
Losing Adrianza represented the initial regular-season personnel setback for the Giants, given his versatility and improved offense. The latter was particularly startling -- and welcome, given Adrianza's light hitting in previous years. This season, he was 3-for-10 with a double and a line-drive home run last Saturday off Kershaw. But Adrianza's promise was interrupted by the foul ball he smashed Thursday off his foot, causing the injury.

"It's terrible news," Bochy said. "The kid was doing such a nice job in the early go in his role. ... He was really putting it together. He was our hottest hitter off the bench."
Adrianza also was beginning to gain consistency in 2014 when a midseason hamstring injury shelved him for the majority of the season's second half. "He's had some tough breaks," Bochy said.
Said Adrianza, "It's kind of disappointing, but I have to look forward and see this as a situation to come back and do the things I've been doing."
Williamson, who had a 10-game stint with the Giants toward the end of last season, hit .276 with two home runs, five RBIs and an .852 OPS in seven games with Sacramento. This followed Williamson's encouraging Cactus League effort (.298, five homers, 14 RBIs, 1,002 OPS). He was outperformed the other leading candidate for a promotion, fellow outfielder Jarrett Parker (.154 batting average, no homers or RBIs in seven games for Sacramento).
