SEATTLE Sonny Gray's tuneup for his first stint in the postseason went as A's manager Bob Melvin hoped.
But it came with no guarantees that Gray will be in Oakland's rotation for the American League Division Series against Detroit, at least until it's officially announced.
"You can make your own assumptions," Melvin said. "I really don't want to say anything right now until we have it all decided and that probably happens at some point in time (today)."
Gray threw five shutout innings, Oakland had two four-run innings, and the A's closed the regular season with a 9-0 win over Seattle in Eric Wedge's final game as Mariners manager.
The A's now turn their attention to the ALDS against Detroit that will begin Friday in Oakland, while Seattle enters the offseason with another managerial search on the docket.
Oakland is likely to start 18-game winner Bartolo Colon in Game 1, and from there the A's have a multitude of options.
There's Jarrod Parker (12-8), Gray (5-3), Tommy Milone (12-9), Dan Straily (10-8) and A.J. Griffin (14-10) all serving as options that Melvin can use to fill out his rotation for the remainder of the series.
"It would be nice. Hopefully, I'm fortunate enough to be able to do that," Gray said. "If my name gets called, I'll definitely be ready."
Oakland gave a few of its starters the finale off, while others made cameos before getting a rest before the postseason. Jed Lowrie, Coco Crisp and Yoenis Cespedes all sat Sunday, while Josh Donaldson, Brandon Moss and Chris Young were lifted early.
"We have a bigger goal right now, and that is to go deep in the playoffs and probably didn't want anything freak to happen on a day like today," Donaldson said.
Gray (5-3) gave up two singles in the first inning and walked two batters in the third, but otherwise got through his final regular-season outing without any trouble.
Gray struck out eight and allowed three hits.
Oakland finished the regular season with 96 victories, the most since the A's reached that total in 2003.
