SAN FRANCISCO -- Angel Pagan has balanced his record-breaking offensive performance with defensive improvement.

The Giants center fielder entered Thursday having been charged with five errors, half of his 2011 total with the New York Mets. Pagan attributed most of last year's miscues to an overzealous approach.

"We were in desperate need of some defense and I was just trying to be Superman, I guess," said Pagan, who has started 143 games in center.

Pagan said that he has remained aggressive.

"That's the way I like to play, trying to prevent the extra base," he said. "I don't care if I get an error, because I'm still being a good outfielder. It's not like I'm missing catches or overthrowing people. I'm very confident in the outfield. I never have any doubts. I know my routes; I know my limits."

Manager Bruce Bochy said that Pagan, 31, has exercised better judgment in the outfield.

"He has really cut down on the mental errors that he supposedly had in New York," Bochy said. "He's really done a great job here. He's so athletic and he covers a lot of ground out there, but he's been playing smart, too -- throwing to the right base and hitting the cutoff man."

Worth noting

• Giants closer Brian Wilson, recovering from Tommy John elbow surgery, told an Associated Press reporter that he will begin throwing on flat ground Oct. 19. "I will be available Opening Day. I will be 100 percent at Spring Training," Wilson vowed.

• Matt Cain and Madison Bumgarner are the first pair of Giants pitchers to win as many as 16 games apiece since John Burkett and Bill Swift won 22 and 21, respectively, in 1993. Only three other pitching duos in the Majors have been that prolific this year: Detroit's Max Scherzer and Justin Verlander (16 wins apiece), Texas' Matt Harrison (17) and Yu Darvish (16) and St. Louis' Lance Lynn (17) and Kyle Lohse (16).

• The Giants have reached the 90-victory plateau for the 18th time since the franchise moved to San Francisco in 1958. They've achieved this distinction in seven of the last 13 seasons.
