When Josh Donaldson looked across the diamond into the Cincinnati Reds' dugout Tuesday night, he saw a pretty good team that nonetheless doesn't have a whole lot on his own.

"They have some bigger names, but I think we kind of resemble each other in a lot of ways," said Donaldson, whose two-run homer in a four-run third inning was the big blow in a 7-3 A's victory over the Reds before 17,506 at the Coliseum.

The A's actually might be a shade better. Over the past 162 games dating to July 1 of last season, the A's are a gaudy 102-60. The Reds over their last 162? Three games worse at 99-63.

"Both teams are fairly patient at the plate, and up and down the lineup, you have guys that can leave the yard," said Donaldson, whose 11th home run highlighted a seven-run pelting of Reds starter Bronson Arroyo (6-6), who had allowed just five earned runs total in his four previous June starts.

To be sure, A's manager Bob Melvin can finally field something close to his optimum batting order, and Tuesday night, the A's showed the potential potency of that lineup if it can just stay healthy for awhile.

Albeit missing catcher John Jaso, who is still being bothered by a minor hand injury, the lineup Oakland anticipated at season's outset is pretty much intact now, and it staged an impressive offensive show in winning the opener of an important eight-game homestand against N.L. Central foes, including two of the best in the Reds and the St. Louis Cardinals.

Perhaps the most encouraging sign was that virtually everybody got into the act during the early offensive outburst. Coco Crisp walked twice and scored twice. Josh Reddick had an RBI double. Brandon Moss had a double and sacrifice fly. Yoenis Cespedes and Seth Smith delivered run-scoring singles. Jed Lowrie had a single and eventually scored in the four-run rally. Even catcher Stephen Vogt, called up Tuesday to fill in for Jaso, had a sacrifice fly.

"When everything's rolling pretty well, we have a lot of guys in the lineup who can do some damage," said Donaldson. "Not just hitting home runs, but just getting on base."

Melvin concurred.

"That's when we're successful, when we're making a pitcher work," the manager said. "Sometimes the guy who gets the key hit isn't really the key at-bat in the inning. It seemed like every hit we had culminated by Donaldson was a big hit in the game because you feel like against a team like that, you better put some runs on the board when you have the opportunity to do it."
