MIAMI -- Sergio Romo looked almost unrecognizable Thursday.

Gone were the thick head of hair, the flowing sideburns and the bushy beard. The new-look Romo had close-cropped hair topped by a fake Mohawk (widely known as a "fauxhawk"), much trimmer sideburns (though they still went from ear to ear in "chinstrap" fashion) and barely more than a goatee sprouting from his chin.

Romo knew that he wanted the Marlins' visiting clubhouse barber, known to many as Hugo, to cut his hair. The right-hander trusted Hugo so much that he allowed him free rein.

"'I'm going to walk in and you determine how I walk out,'" Romo said he told Hugo.

Romo was planning to put up a post-haircut photograph on Twitter later on Thursday.

"It'll be fun to see the response I get," he said.

What does his wife think?

"We'll find out," Romo said.

Giants hope Theriot can provide spark

MIAMI -- Ryan Theriot has always hit consistently. Manager Bruce Bochy hopes that Theriot can begin doing that for the Giants.

San Francisco reinstated Theriot from the 15-day disabled list Thursday, and Bochy plans on playing him in consecutive games beginning Friday to give the .280 lifetime hitter a chance to establish himself. Before being sidelined with a strained right elbow, Theriot hit .179 in 20 games. He didn't start Thursday because Bochy thought he might be fatigued from traveling all day.

The Giants have sorely missed the offensive production Freddy Sanchez brought them. Since Sanchez, who's recovering from a dislocated right shoulder and battling back pain, doesn't appear ready to return anytime soon, the Giants need somebody to fill the void at second base.

Emmanuel Burriss, who has received most of the activity at that spot, entered Thursday hitting .202.

"It's fair to say that Manny has been struggling," Bochy said.

Theriot, a six-year veteran, could serve as a decent replacement for Sanchez if he approaches his career standards.

Overall entering Thursday, Giants second basemen ranked last among their National League counterparts in runs (10), on-base percentage (.237) and OPS (on-base plus slugging percentage, .431), and next-to-last in RBIs (seven) and batting average (.188).

"We need to get our bats going," Bochy said.

Worth noting

• Giants manager Bruce Bochy said Thursday that he is contemplating giving shortstop Brandon Crawford a rest soon. Crawford has started 39 of San Francisco's first 45 games. Bochy said that he would lean toward Emmanuel Burriss as his first choice to replace Crawford, though Ryan Theriot also would be a candidate.

• Bochy noticed the festive nightclub that's situated beyond the outfield wall at Marlins Park, which the Giants visited for the first time Thursday. "I'll have to keep my eyes on my left fielder to make sure he's watching the game," Bochy jokingly said.

• Though Brandon Belt entered the game hitless in his last 13 at-bats, with eight strikeouts, Bochy opted to start him at first base instead of Aubrey Huff, who happened to be 0-for-12 lifetime against Marlins right-hander Anibal Sanchez. Huff likely will re-enter the lineup Friday against Josh Johnson.
