Bochy grateful for infield depth behind Scutaro

SAN FRANCISCO -- No official moves have been announced, but Giants manager Bruce Bochy reiterated Thursday that starting second baseman Marco Scutaro (back) and lefty reliever Jeremy Affeldt (knee) will start the season on the 15-day disabled list.

Both moves will have trickle-down effects on the rest of the team, leaving the door open for some lesser-known players to make the Opening Day roster. Joaquin Arias was penciled in as the starting second baseman Thursday, something he could be doing regularly as Scutaro tries to get his back right.

"I'll mix it up and try to match it up as well as I can," Bochy said. "I think with Joaquin's experience and the defense that he gives you, he'll get the lion's share of the playing time."

Rookie Ehire Adrianza and non-roster invitee Brandon Hicks -- who had a "tremendous" spring, according to Bochy -- are also poised to make the team as backup infielders and could see time at second base.

As for Scutaro, Bochy didn't sound optimistic that he would have the second baseman back on the field April 4 when he's eligible to return. The plan is to have Scutaro join his teammates in San Francisco on Friday, run through baseball activities and go from there.

"We've been spending six or seven weeks on this," Bochy said of Scutaro's attempt to get healthy. "It's been a slow process, frustrating for him. But what's important is that we get him right because it is so early in the season. If it takes another couple weeks, I'll take him for five months."

Scutaro, 38, is in the second season of a three-year, $20 million deal he signed following the 2012 campaign, when he played a big role in the team's World Series run. But his back has given him lingering problems since midseason last year, and it limited him to just one Cactus League contest this spring.

Adrianza played in nine games as a September callup in 2013 and is known for his solid work with the glove. While he played almost exclusively at shortstop as a Minor Leaguer, Brandon Crawford figures to be entrenched as San Francisco's starter for years to come. Thus, Adrianza has been working hard to prove to the coaching staff he can also handle second and eventually third base.

"I want to show them that I can play wherever they want me to play," Adrianza said. "First, third, second, whatever. I just want to be here and help the team win."

Adrianza said he feels natural at second base, because it's where he played before he was signed as a free agent out of Venezuela in 2006. The 24-year-old said he's been relying on the advice of his countryman Scutaro as he tries to make a lasting impression on the Giants' front office.

"I feel bad for Scutaro, because he's one of the best players in the big leagues, for me," Adrianza said. "It's an opportunity. I want to be here because of my work. I don't want to be here because he's hurt. For me, it's keep working hard and see what happens in these few days."

As Bochy noted, the team also has MLB-tested Nick Noonan in Triple-A Fresno to call on if needed.

"It's nice to have this depth to call on," Bochy said. "[They're] probably all going to play a part in our season."

Lineup close to taking shape for Opening Day

SAN FRANCISCO -- It's hard to keep up with all the lineups manager Bruce Bochy has created late in Spring Training, but he hinted that Thursday's order against the visiting A's was a sneak preview of the Opening Day look for the Giants.

"This could be our lineup," Bochy said.

No surprise seeing Angel Pagan leading off the order Thursday, but Hunter Pence in the No. 2 hole is something new. Pence hasn't taken an at-bat at the second spot since he joined the Giants during the 2012 season, but the high-energy outfielder could see some time there in 2014.

"He's done it. When he came up [to the Majors] he hit in the two-hole," Bochy said. "He does give you speed, plus he's a guy that can hit the ball out of the ballpark, too. That's not a bad thing to have at the top of the order."

Traditional baseball logic usually amounts to two table setters atop the lineup, but throughout MLB in 2013 many sluggers occupied the No. 2 spot, including heavy hitters Mike Trout, Jose Bautista and Robinson Cano. Michael Morse, who hit No. 2 in three straight games this week, also was tabbed by Bochy as a potential second hitter in the 2014 lineup.

"If those guys are hitting in the two-hole, that's pretty cool," Morse said of the aforementioned All-Stars who hit second in 2013. "That's a good group to be a part of."

Morse said it "doesn't matter" which spot he takes in the lineup, where he's expected to be an everyday fixture in left field. On Thursday, he batted sixth behind the 3-4-5 combo of Brandon Belt, Buster Posey and Pablo Sandoval, while Joaquin Arias, Brandon Crawford and pitcher Tim Hudson rounded out the order.

Giants excited to feed off AT&T Park's energy

SAN FRANCISCO -- About 24 hours after wrapping up their 2014 Cactus League schedule, the Giants took batting practice on a breezy, sunny day by the bay at AT&T Park on Thursday.

Now that Arizona is in the rearview mirror, Giants manager Bruce Bochy said he's looking forward to playing in front of the home fans.

"It's always had that energy. I saw on the other side from being here," Bochy said of AT&T Park, which gets set to host its 15th season. "You see it every night, it's so consistent. Every game it's special. There are probably only two or three clubs that have what we have here. That's special and I think the guys really appreciate it, and we know how lucky we are to have this kind of fan base and support."

Giants fans have put together an MLB-best 246-game sellout streak heading into the home opener on April 8, following a seven-game road trip through Arizona and Los Angeles to start the season. Bochy said he's happy the team gets to tune up with a three-game set against the neighboring A's, in a Bay Bridge Series matchup that always gets the fans riled up.

"Even though they're still exhibition games, they're similar to a normal game," Bochy said. "It helps get you ready for the season. We'll have three games that will have some intensity to them because of two rivals."
