SCOTTSDALE, Ariz. (AP) _ Luis Gonzalez's third double of the game drove in the go-ahead run in the top of the ninth inning as the Arizona Diamondbacks defeated the San Francisco Giants 6-4 Friday.

Danny Bautista had four hits and drove in three runs and Danny Klassen homered for the Diamondbacks.

Barry Bonds and Jeff Kent homered for the Giants, who have lost five of six.

Arizona starter Miguel Batista pitched a one-hitter over five innings, walking two and striking out five. Jason Jacome (1-0) pitched a scoreless eighth to record the victory. Matt Mantei struck out two of the three batters he faced in the ninth to pick up the save.

Giants closer Robb Nen (0-1) took the loss after giving up his first two runs of the spring in six outings.

Nen walked Craig Counsell to open the ninth, then Gonzalez drilled a double into the right-field gap. Bautista followed with a single.

Gonzalez doubled twice off Giants starter Shawn Estes, who allowed three runs and nine hits in 5 2-3 innings.

``He can hit,'' Estes said of Gonzalez. ``He hit a good fastball away with two strikes and a good fastball in ahead in the count. I'll have to try something different with him the next time.''

Bautista singled in a run in the first, and tripled in another in the third.

Bonds hit his third homer of the spring in the sixth, a three-run shot off Mike Morgan that tied the game. Kent hit the next pitch for his third home run.

Klassen, who doubled in a run earlier, homered off Tim Worrell to lead off the eighth.

Notes: Gonzalez now has a team-high eight doubles and 16 RBIs. ... Arizona 3B Matt Williams sat out the game with a bone spur. He's slated to return to action on Monday. ... Kent is 18-for-37 (.486) over his last 14 games. ... Giants RHP Joe Nathan, attempting to come back from offseason shoulder surgery, threw four innings in a minor league game, allowing one run. ``The more I threw, the looser I got,'' said Nathan, who has allowed 12 runs in four spring innings.
