The Rays and A's begin the season's final month atop the American League Wild Card standings, with Oakland holding a 1 1/2-game lead over Tampa Bay for the top spot.
The A's closed August on a high note -- winning six of eight -- while the Rays sputtered, dropping six of their last seven. Sunday's series finale at O.co Coliseum is the final meeting of the season between the two clubs.
"For us, you eye the finish line, especially when you get to Sept. 1. So every game has a little bit of a different feel," A's manager Bob Melvin said. "[Friday] that was certainly the case. Playing these guys, one of the better teams in all of baseball, close game, two great pitchers: It did have a playoff type atmosphere to it."
The A's -- also two games back of the Rangers in the AL West -- send right-hander A.J. Griffin to the mound Sunday as Oakland looks for the sweep. Griffin earned the win in his last outing despite giving up four runs on seven hits. He continued to get bit by the long ball, serving up two home runs to the Tigers.
He'll face a much different offense Sunday, as it's the bats that have been Tampa Bay's undoing during its recent slide. The Rays are batting .217 with only one home run in their past seven games, including a .190 mark with runners in scoring position.
The Rays will try to break that trend for right-hander Jamey Wright, who was officially named the starter following Saturday's 2-1 loss. It will be the 38-year-old's first start since July 2007.
Wright has a 2.97 ERA in 54 appearances over 57 2/3 innings this season for the Rays.
Rays: Four to join squad
• Outfielder Delmon Young, right-hander Josh Lueke and catcher Chris Gimenez traveled to Oakland on Saturday and will be added to the roster on Sunday, when Major League rosters expand to 40. Designated hitter Luke Scott, on the disabled list since Aug. 18 with back spasms, also will be activated.
• The Rays' 49 errors are second fewest in Major League history through 134 games behind this year's Orioles (40).
A's: The streak goes on
• Saturday's win allowed the A's to close August with a 14-13 record, the ninth straight month Oakland finished .500 or better dating back to last June. It's the longest such streak in franchise history since a 10-month stretch from June 2002 to September 2003.
• Melvin said he expects three players to join the A's on Sunday when rosters expand, though he did not reveal names. More callups are expected Tuesday after the Minor League seasons end.
• Oakland's Brandon Moss is batting .333 with seven home runs and 14 RBIs in his past 11 games.
