The limp-lumbered Giants will make plenty of changes to their roster before they report to spring training. That much is obvious.

But is it time to consider alterations to AT&T Park, too?

“Without a doubt,” veteran infielder Mark DeRosa said before the Giants’ 3-1 win over the Colorado Rockies on Monday night. “Maybe you don’t move the fences in. But I think you saw maybe two balls go out to right-center this year. So they definitely should cut the corner. Have another wall go across. Maybe put something nice back there. I don’t know. Does San Francisco have a city tree?”

Even lawn flamingoes would be a welcome sight to most Giants hitters, if it reduces that 421-foot crown in right-center. They’re all too accustomed to getting good wood on a pitch, only to see it settle into a glove.

Entering their final two home games of the season, the Giants have hit just 40 home runs at AT&T Park — the fewest by any major league club in its own ballpark. The Giants have hit almost twice as many home runs in road grays — 79 in 81 games.

Compare that with the Arizona Diamondbacks, who also hit 79 home runs on the road. But Arizona entered Monday with 90 at lively Chase Field — essentially a 50-homer advantage over its nearest rival in the N.L. West.

The power outage was a killer to the Giants when they failed to win seven consecutive home series after Aug. 1. Their lineup wasn’t built to manufacture single runs, and manager Bruce Bochy doesn’t tend to play for them.

It isn’t a new suggestion to cozy up the dimensions at AT&T Park. Managing partner Bill Neukom said the subject has come up occasionally among club officials, if only casually.

“I wouldn’t describe it as a serious subject that’s been looked at closely,” Neukom said. “That doesn’t mean it might not become one, but at this point I don’t foresee that.”

Neither does Bochy, who began a habit of nipping player complaints in the bud when he skippered the San Diego Padres at cavernous Petco Park.

“There’s not been one word,” Bochy said.

The talk is serious in New York, though. As they finish their third season at Citi Field, Mets officials acknowledge they are likely to lower the 16-foot wall in left field. It’s the ballpark equivalent of hiking up a skirt.

“To some extent, it’s a question of entertainment,” Mets general manager Sandy Alderson told MLB.com. “I think offense is appealing. Offense sells.”

The Giants have no trouble filling seats. They set an all-time franchise attendance record Monday, selling out for the 79th consecutive time to draw 3,303,060 fans.

Were they not entertained? Well, not always. The Giants’ injury-ravaged offense scored the fewest runs in the National League, depriving their brilliant pitchers of a chance to defend the team’s first World Series championship in San Francisco.

Pablo Sandoval has hit a team-leading seven home runs on the shores of McCovey Cove. That would be the Giants’ smallest team-leading total at home since 1975, when Willie Montanez, Bobby Murcer and Gary Thomasson each hit five at Candlestick Park.

Hitting coach Hensley Meulens is in lock-step with Bochy: The park shouldn’t be an excuse.

“Last year we had a better year and scored more runs there,” Meulens said. “We just have to think doubles and triples in our park. It’s not going to go away. Even if they change the dimensions, the ball still doesn’t carry as well because it’s cold or the wind is blowing.”

Former Giant Aaron Rowand so loathed hitting at AT&T Park that his constant complaining hastened his release in August. Other current Giants know to shut their yapper about the issue, lest they want to hear from management.

Free agents know the score, too. When the Giants shop for hitters, they either must pay a hefty premium to mitigate the ballpark issue, as they did with Rowand’s five-year, $60 million deal, or shop for players in desperation mode, as when they signed Huff before the 2010 season. Even if they offer top dollar to Carlos Beltran this winter, he’ll probably seek warmer and cozier environs.

Of course, the flip side is that the Giants are built around their pitchers, who brilliantly use AT&T Park to their advantage.

Perhaps the key question is this: Is the ballpark fair?

Neukom said yes. Bochy said yes. Meulens said it doesn’t matter. It is what it is.

As for DeRosa?

“I don’t think any hitter should make excuses,” he said. “But I’ll say this: It does weigh on your confidence, and over the course of 81 games, it does beat you down. Not only are those balls not going out of the ballpark, but they’re outs. You’re not rewarded for hitting a ball 410 feet.

“That’s the biggest thing. It’s a shot to your ego.”
