SAN FRANCISCO (AP) -- Damon Minor made one wise investment in his

eyesight when he underwent laser surgery last September.

He's beginning to reap the benefits.

Minor singled in Barry Bonds with one out in the 10th inning to

lead the San Francisco Giants to their first three-game sweep of

the season and sixth straight win, 5-4 over the discouraged Arizona

Diamondbacks on Thursday night.

Tyler Walker (4-0) pitched a perfect 10th with two strikeouts

for the win. Minor, called up Tuesday when first baseman J.T. Snow

went on the disabled list with a knee injury, singled through the

infield to right field off Jose Valverde (0-2) to score Bonds, who

was intentionally walked, for the winning run. Valverde gave up a

go-ahead double to Pedro Feliz on Wednesday night.

Minor went 2-for-3 with two walks -- getting his first hit in the

majors since Sept. 5, 2002, when he doubled in the fourth.

"It's a thrill to be back here," said the 30-year-old Minor,

who not only improved his vision but also lost more than 30 pounds

during his yearlong absence from the majors. "But it's only one

game. There are still four months yet."

The Diamondbacks tied it on Danny Bautista's solo home run off

closer Matt Herges with two outs in the ninth. Herges struck out

Matt Kata and Luis Gonzalez looking and appeared headed for his

third save in as many nights until Bautista hit an 0-1 pitch over

the wall in left-center for his seventh homer and second this week

in the ninth inning.

It was only the third blown save for the righty all year, and it

spoiled what would have been starter Dustin Hermanson's first win

in more than two months.

"As long as we're winning these games it doesn't matter who

gets it," Hermanson said.

Michael Tucker hit a two-run triple and added a sacrifice fly

for the Giants, who won without getting a home run from Bonds. The

six-time NL MVP homered the previous two nights, but settled for a

single and three intentional walks.

"I'm tired," was all Bonds could muster as he slowly left the

clubhouse. He has been battling back problems and went hard against

the left-field wall to catch a well-hit ball by Shea Hillenbrand in

the fourth.

A.J. Pierzynski hit a go-ahead double in the fourth to score

Minor, then Pierzynski came home on Tucker's sacrifice fly, but the

bullpen couldn't hold a two-run lead.

The Diamondbacks lost their fourth straight and seventh of eight

to fall 13 games under .500 -- their worst record since the club's

inaugural season in 1998, when Arizona finished 16 games under at

65-97.

Hermanson allowed three runs on six hits, struck out one and

walked three in 5 2-3 innings. He hasn't won since beating

Milwaukee on April 13. The right-hander hasn't recorded a decision

since losing back-to-back outings April 20 and May 8.

Arizona added a run on Scott Eyre's bases-loaded passed ball in

the sixth that allowed Steve Finley to score. Eyre walked

pinch-hitter Carlos Baerga to load the bases again, then Chad Tracy

grounded out to end it.

The bullpen ran into trouble in the seventh, too. Jason

Christiansen gave up a single to Kata and walked Gonzalez before

Jim Brower relieved. Brower immediately allowed a single to

Bautista to load the bases. Steve Finley followed with a chopper

that second baseman Neifi Perez threw home to save a run.

Hillenbrand then hit into a double play to end the threat.

"Jim getting that double play was the turning point," Walker

said.

The Diamondbacks' frustration is starting to show.

Manager Bob Brenly swapped Bautista and Hillenbrand in the

batting order to mix things up -- Bautista hit fourth and

Hillenbrand sixth. It was also an effort to get Gonzalez more

pitches to hit in the No. 3 hole. The three combined to go

4-for-13.

Bonds drew his majors-leading 61st, 62nd and 63rd walks this

year -- in just 38 games.

Brenly found out that whether you walk Bonds or pitch to him,

the slugger makes opponents pay.

"There's no upside," Brenly said. "He doesn't swing at bad

pitches. He waits for something he can mash. I said coming in we

wouldn't pitch to him if he could tie the game or give them the

lead and we stuck to that. Bottom line, we had some chances. We

don't throw strikes, we don't come up with the big knock.

"It's like Groundhog Day. I get tired of talking about it. We

made mistakes and we missed opportunities. I'd like to win some of

these once in a while."Game notes
The Giants grounded into three double plays, giving them a

majors-leading 52. ... Bautista also homered in the ninth Monday at

Florida. ... Arizona's Steve Sparks, a 38-year-old knuckleballer,

has lost his last three decisions. ... Bonds has 33 intentional

walks and is well on pace to break his own major league record of

68 he set in 2002.
