ST .PETERSBURG, Fla. (AP) Khris Davis helped Oakland win another close one.
Davis led off the 10th inning with his major league-leading 42nd homer, and the Athletics beat the Tampa Bay Rays 2-1 on Friday night.
''I've always said he's one swing away from winning a game for you,'' A's manager Bob Melvin said. ''He's developed a knack for hitting good pitching and hitting dramatic homers late in games.''
Oakland improved its majors-best record in one-run games to 29-12 and extended its lead for the second AL wild card to nine games over the surprising Rays. Tampa Bay has 16 games left.
The A's remained 1 1/2 games behind the New York Yankees for the first wild card. The Yankees beat Toronto 11-0.
''We're competing for a spot. Every game is precious,'' Davis said.
Davis' drive to center off Jaime Schultz (2-1) was his 40th this season as a designated hitter. He joins David Ortiz has the only DHs to have 40 or more homers.
Davis set an Oakland record with his 16th homer in the seventh inning or later.
The A's had just three hits against nine Tampa Bay pitchers.
''Today stunk just in the fact that we had an opportunity and we didn't capitalize,'' Rays manager Kevin Cash said. ''It's tough to pull negatives from what this group has done and how they performed tonight.''
Blake Treinen (7-2) went two scoreless innings for the win.
Matt Chapman doubled for the first A's hit with one out in the fourth and scored on Matt Olson's single.
Tampa Bay tied it later in the fourth when Tommy Pham extended his hitting streak to 17 games with a pop-fly double into shallow center field and crossed the plate on Joey Wendle's base hit.
''They didn't give us much,'' Rays third baseman Matt Duffy said. ''A close, hard-fought game.''
Oakland reliever Shawn Kelley worked out of a second-and-third, no-out jam in the sixth.
''That was a Houdini inning,'' Melvin said.
Athletics starter Edwin Jackson allowed one run and four hits in five innings.
Reliever Diego Castillo opened the game for the Rays and struck out four over two perfect innings.
Sergio Romo retired all three batters in the ninth in his second appearance for the Rays since Aug. 25. He recorded a two-out save on Sept. 4 at Toronto.
The Athletics are 12-5 in extra innings.
''It's fun baseball that we're playing right now and every day it's a different person coming through in clutch situations,'' Jackson said.
MAKING A CASE FOR CY
The Rays have put out a handbill supporting Blake Snell's AL Cy Young Award bid titled ''Attack of the Cy Zilla!'' It includes a quote from Boston manager Alex Cora saying Snell has ''been great against everybody.'' Red Sox lefty Chris Sale is also a contender. Snell, whose nickname is Snellzilla, leads the majors with 19 wins.
TOUGH LOSSES
Tampa Bay is 25-29 in one-run games. ... It was the Rays' 14th loss when allowing two runs or fewer, which is most in the majors.
NUMBERS
Chapman has 23 doubles and 38 extra-base hits since the All-Star break. ... Oakland C Jonathan Lucrory threw out two runners on stolen base attempts. ... Athletics RF Stephen Piscotty had his 14-game hitting streak end after going 0 for 4.
TRAINER'S ROOM
Athletics: RHP Trevor Cahill (upper back) will miss his next scheduled start. ''He had a trigger-point injection,'' Melvin said. ''Hopefully that alleviates it.''
Rays: Duffy (lower back) started after being out of the lineup the previous three games. ''I don't think the pain is completely out of there but he wants to be in there,'' Cash said.
UP NEXT
Tampa Bay and Oakland, two of the primary teams using relievers as openers to start games, will employ the strategy against each other for the first time Saturday night. ''It's just trying to take advantage of what you have,'' Melvin said. Tampa Bay will go with RHP Ryne Stanek (2-3), while Oakland counters with RHP Liam Hendriks (0-1).
