OAKLAND -- If the A's first win of 2013 requires a title, it would definitely have to be "Night of the Newbies," at least at the plate.

After a hushed offensive start in their first two games at the Coliseum (6 for 60, .100, and a lone run), the A's finally broke out with the bats, but only one of the runs driven home in a 6-2 victory over the Seattle Mariners on Wednesday night was by a player who was with Oakland last season.

New shortstop Jed Lowrie drove in three runs with a tiebreaking two-run double in the fourth inning and a solo homer in the seventh. But the A's also got a gutty, two-out, two-strike RBI single from first baseman Nate Freiman in his first major league at-bat as well as a solo homer from outfielder Chris Young in his first start, immediately following Lowrie's blast in the seventh.

"The first two games, I think we were trying to win the game all by ourselves," said Lowrie. "But after a game like this, I think we'll get in our rhythm."

Speaking of getting into a rhythm, Tommy Milone (1-0) certainly did after an uncharacteristically rocky start -- two first-inning home runs in a home park where he allowed just six all of last year. But he ended with more familiar mastery, pitching seven innings and retiring 17 of the final 18 hitters he faced, including the last 10.

If all that wasn't enough to get a crowd of 15,162 buzzing, second baseman Scott Sizemore, playing in his first game since Sept. 28, 2011, doubled in his first at-bat. Sizemore missed all of last season with a torn ACL in his left knee, suffered during his first 2012 spring training workout.

But nobody was a happier newbie after this game than Freiman, acquired on waivers little more than a week ago from Houston. Freiman had a terrific debut -- singles in his first two trips, a hard out to center field in his third at-bat and a sweet foul pop catch near the Mariners dugout.

"He was like a kid in a candy store during batting practice, let alone the game," said manager Bob Melvin. "This is one of those days he'll never forget."

Freiman's first at-bat in the second inning against Seattle veteran left-hander Joe Saunders (0-1) was a doozy. He fell behind 0-2, but worked back to an even count and lined a sharp single up the middle to bring home Josh Donaldson, who had doubled to lead off the inning.

"I was trying to not think that it was my first at-bat," Freiman said. "Two outs, runner on third, we're down 2-0, I just really wanted to get that run in. I just tried to shorten up and get something on the barrel to the middle of the field."

The 6-foot-8 Freiman clapped as he ran to first base, then looked up and spotted his parents in the stands. He had no problem locating them.

"That was the little kid in me there," said Freiman. "I could see my parents standing. My dad's big like me, so I had no problem spotting him."

Yoenis Cespedes tied the score 2-2 with a bases-loaded sacrifice fly in the third, and Lowrie put the A's ahead in the fourth with a two-run double to left-center with Josh Reddick and Coco Crisp aboard.

The Mariners got off to a quick start with first-inning solo homers by Gutierrez and Michael Morse, the latter's third in two days, for a 2-0 lead against Milone, who looked to be on the ropes when Jesus Montero singled and Jason Bay walked to open the second.

But after a Robert Andino double-play grounder to third, the second-year left-hander allowed just one more baserunner -- Montero on a two-out single in the fourth.

  • Shortstop Hiro Nakajima (hamstring) is slowly but surely increasing his baseball activity. Infielder Adam Rosales (intercostal strain) might begin throwing in the next few days.

  • The A's claimed right-hander Will Harris off waivers from the Colorado Rockies and optioned him to Triple-A Sacramento. Right-hander Josh Stinson, claimed last week from Milwaukee, was designated for assignment.
