PHOENIX -- Scott Sizemore has been waiting for this for more than a year -- a four-hit game that helped the A's to a 9-7 exhibition victory over the Milwaukee Brewers on Monday.

A knee injury that required surgery wiped out Sizemore's 2012 season on the first day of spring training last year.

He was the A's third baseman then, but now he is one of a handful of candidates vying for the starting job at second base. Until his four singles against the Brewers, he was hitting .171. He scored two runs and had two RBIs against Milwaukee and raised his spring average to .244.

"That's what we were waiting for," A's manager Bob Melvin said. "That's the way Scott hits, up the middle and to the opposite field. That's huge."

Sizemore had been grinding, and with the demotion of Jemile Weeks on Sunday, there was speculation about how long Sizemore could hang on.

"The way I played the first two weeks was not up to major league levels," Sizemore said. "It's nice to see this. I've been seeing the ball a lot better the last four or five games, getting my timing together. I'm getting to where I can trust my swing."

That isn't the case with Hiroyuki Nakajima, who is in an 0-for-21 skid and didn't play Monday, with Melvin saying the shortstop needed a day off.

  • Bartolo Colon started against the Brewers, then was followed by Dan Straily.

    Both pitchers were scheduled for starting assignments Monday, but Melvin didn't want to send one of them to the minor league camp.

    "When you are trying to ramp up for the season, you don't want to pitch in a minor league game," Melvin said.

    Colon went five innings and was in command for all but the fourth inning, when he gave up three runs after a pitch that he thought should have been called a strike went against him.

    "He threw all of his pitches," Melvin said. "That one call might have affected that one inning, but he threw the ball well."

    Straily threw two perfect innings, then allowed eight hits and four earned runs in one-plus innings before Pedro Figueroa bailed him out of a bases-loaded jam in the ninth.

    "I just didn't get enough outs," said Straily, who is scheduled to be the fifth starter the first time through the rotation.

    Colon's suspension for using performance-enhancing drugs will be over after the first spin through the rotation, and it's possible Straily will lose his spot.

    "We wanted Straily to finish the game," said Melvin, who praised Figueroa for working out of the ninth-inning jam.

  • Andy Parrino, back after a few days off so he could be in San Diego for the birth of his son, was a defensive replacement in left field and made threw out a run at the plate in the eighth.

  • Newly acquired first baseman Nate Freiman made an error on the first ball hit to him, but after that his day improved. He made two nice catches at first base, drew a walk and doubled.

  • Third baseman Josh Donaldson joined Sizemore in having four hits, including two doubles and a home run. His average is up to .298 and he has three homers, which doesn't count the two he lost because of a rainout against the Mariners. Donaldson added a terrific leaping catch as well.

  • Chris Young had his biggest swing of the spring, a fourth-inning grand slam that broke open the game. It was the second Cactus League homer for Young, who is hitting .231.
