There was speculation that he wasn't pleased about being replaced by Bobby Kielty in the starting lineup on Saturday against the Giants. Payton had a key double in Friday's win and looked frustrated in his one at-bat on Saturday -- when he flied out to left field.

"I have nothing to say to anybody about anything," Payton said before Sunday's game.

But when he got on the field on Sunday, his bat did all the talking, as he collected four hits and three RBIs in the A's 10-4 win against the Giants at AT&T Park.

After his big day, Payton escaped the media again and left the A's clubhouse before any reporters had a chance to interview him.

Payton hit two RBI singles and a triple into the right-center-field gap that scored Dan Johnson from first in the ninth inning. It was the 12th time in his a career and the second time this season that Payton has had four hits.

The 33-year-old outfielder was acquired in 2005 and was the A's fourth outfielder when the season started.

He saw some playing time in April, when Nick Swisher played first base, and his playing time increased in right field with Milton Bradley having two stints on the disabled list.

After battling through April, Payton got his swing back mid-May and has kept it through June. His batting average was at .183 on April 28, and after seven multihit games in June, Payton has boosted his average to .278.

"Everybody here deserves to be here," said Johnson. "We have a lot of guys that are starters, not role players. Hopefully, the situation will probably work itself out. You never know in this game."

A's manager Ken Macha said at the beginning of the year that it could be tough making everybody happy in his crowded outfield. With Kielty leading the team with a .288 average and hitting .364 with runners in scoring position, it appears that things may be getting hairy in right field.

But Macha didn't feel that way after the game.

"If Jay has a good day, it makes my job easier," Macha said. "If you knock in some runs, you're going to be in the game. This isn't calculus."

Macha was also asked if decisions would become even worse when Bradley comes off the DL.

"I'm not worried about Milton getting back now, I'm worried about San Diego," said the A's skipper, who will start a three game series with the Padres on Tuesday. "And if somebody is worried about Milton getting back, then they have bad focus."

"We'll see how many players we have there, and if we have 25 players, we will rate those 25 while we are there."

After the game, Macha was more willing to talk about A's starter Esteban Loaiza -- who threw his first complete game since May 9, 2004, against Toronto.

"He did a great job at changing speeds," Macha said. "He used his changeup a lot. Every once in a while, he would get inside with a 90 mph fastball and use his cutter. Then he went to the changeup and had the hitters off balance."

Loaiza (3-4) gave up four runs over the first four frames, but after Steve Finley hit a solo home run over the right-field wall, Loaiza allowed just one more baserunner.

"After I gave up the home run," Loaiza said. "I was throwing strikes, keeping the ball low and getting people out. They were waiting for the fastball, sinking and cutter. The [changeup] was working, so I kept with it and I went the whole way."

It was Loaiza's 12th complete game of his career game. The last one he threw was when he played for the White Sox in 2004.

"It's been a long time [since my last complete game]," Loaiza said. "I think that's about 70 starts in two years. It feels great."

The A's bats scored 10 runs on 12 hits, as Jason Kendall contributed with three hits and two runs, and Johnson added two hits and two runs.

Giants starter Matt Cain held the A's to just one hit and went the distance in his last start against Oakland on May 21. But the patient A's hitters drew six walks against the 21-year-old and forced him to throw 105 pitches over his 4 1/3 innings.

Cain (6-6), whose last loss was on May 10, left in the fifth inning after giving up six runs on five hits.

The A's won two in the three-game series at San Francisco and have won six their last seven series.
