The Giants were not without distractions on their way to the title, either. First, they dealt with the news that relief pitcher Guillermo Mota was suspended for 100 games for his second violation of MLB's Joint Drug Prevention and Treatment Program.
Then, in mid-August, the "Melk Man" left fielder Melky Cabrera was also suspended, this time for 50 games for elevated levels of testosterone.
Seemingly undaunted, the Giants marched on, capturing the NL West Division title, then storming their way through the playoffs detroying the Detroit Tigers in four straight to capture the World Series championship.
As the winter months rolled on it looked like the Giants were going to just take care of their own, re-signing top contributors from last year. Then in the middle of February Giants president Phil Nukom and GM Brian Sabean surprised everyone with a series of acquisitions. Instead of signing Andres Torres which looked likely, they signed another speed-and-defense player—to compete for playing time in left field with the speedy Gregor Blanco, Hairston who with his 20 homers has more power (and more speed and pateince), was inked.
Sabean hinted at the need to sign a free agent pitcher with starting experience to be the long reliever. A sixth starter in case of injury was a priority. A sound strategy for the Giants.
Jair Jurrjens, the best candidate for the role, was signed to a two year deal.

Just eleven days after the Jurrjens deal Sabean announced the biggest off season deal--- by ANY team.
For a team that’s hit only 22 home runs at home all season, adding a guy capable of jacking four dingers in a single game made some serious sense to the Giants front office. After losing their all star game MVP the San Francisco Giants thanks to two world series crowns, and of course all of those panda hats, 12 dollar garlic fries, posey bobble heads. and Brandon Belt Giraffe hats, were able to sign Left fielder Josh Hamilton to a sever year deal worth north of 120 million.

Buster Olney had this to say about the deal:
Key Arrivals : IF Tony Abreu - Waivers (KC); OF Scott Hairston and Josh Hamilton

Scouting the Starting Pitching
The Giants sported the fifth-best ERA (3.73) from their starters in the National League last season. Lincecum's sub-par season helped elevate what had been the second-best rotation in 2011.
Cain clearly stepped up and took the reins as the ace, throwing the 22nd perfect game in MLB history along the way. At just 28 years of age there's no reason to think that Cain can't continue as one of the dominant right-handers in the National League.
Bumgarner is also maturing into an elite starter, significantly lowering his H/9 rate and WHIP last year, showing solid command of his secondary pitches and getting increasingly tougher against left-handed hitters (.208 BAA last year).
And lets not forget...
Lincecum who is itching to put last year behind him and move forward in a positive direction.
