The San Francisco Giants have had a rather quiet winter. Sure they made two trades in efforts to improve their weak offense, but acquiring outfielder Melky Cabrera for starter Jonathan Sanchez, and Angel Pagan for Andres Torres and Ramon Ramirez was hardly the moves fans were expecting. The Giants essentially said that they would be frugal this offseason and thus far, they’ve kept their word.

But nobody expected the club to struggle re-signing one of its coveted pitchers, especially the ace of the staff.

According to Jon Heyman of CBSSports.com, there is still a “sizable gap” in long-term contract talks between the Giants and Tim Lincecum. The club is believed to have improved upon its initial four-year offer from this summer, but Lincecum is thought to be seeking an eight-year deal.

Those close to the negotiations tell Heyman that both sides are weighing one-and-two-year contracts in case a long-term deal cannot be reached. Considering Lincecum already owns two Cy Young awards, helped the Giants win their first World Series title in San Francisco, and is coming off a season in which he posted a 2.74 ERA with 220 strikeouts, one would think San Francisco would jump at the chance to re-sign one of its prized pitching possessions. But apparently frugal is winning out at the moment.

The Giants also have a decision to make about No. 2 starter Matt Cain, who becomes a free agent at the end of the season. Cain posted career-highs in ERA (2.88) and WHIP (1.083), even though he only won 12 games last season. He’s been repeatedly burned by lack of run support over the years and if the Giants don’t want to pony up to keep him happy, maybe he’ll think about moving on after the 2012 season. He could potentially win 20 games with a team like the Yankees or Red Sox, who are constantly looking for good pitching.

If Buster Posey (leg) makes a full recovery, Pablo Sandoval keeps up on his offseason conditioning, and youngster Brandon Belt takes a major step in his development, the Giants’ offense won’t be as bad as it was in 2011. (Then again, how could be any worse?) But this club is built on its pitching so GM Brian Sabean has a lot of work to do in order to keep guys like Lincecum and Cain around long enough for the offense to finally blossom.
