Chapman home run lifts Athletics past Mets

Rookie Matt Chapman hit a tiebreaking home run in the seventh inning that sent the Oakland Athletics over the Mets 3-2 Sunday, ending New York's four-game winning streak.

NEW YORK » Rookie Matt Chapman quickly atoned for a baserunning blunder by hitting a tiebreaking home run in the seventh inning that sent the Oakland Athletics over the Mets 3-2 Sunday, ending New York’s four-game winning streak.

With the July 31 trade deadline nearing and far back in the NL wild-card race, the Mets now start a 10-game trip, and there’s no telling whether veterans such as Jay Bruce and Lucas Duda will remain on the team when it returns to Citi Field.

Marcus Semien and Khris Davis also homered for Oakland, helping Bob Melvin post his 999th victory as a big league manager. Semien connected on the sixth pitch of the game, and Davis hit his 28th home run in the fourth.

Michael Conforto hit his 19th homer of the season and fifth of the Mets’ 6-4 homestand that followed the AllStar break.

Oakland led 2-1 when Chapman opened the fifth with a double and moved up on a wild pitch by Rafael Montero (1-7). But with no outs, Chapman wandered too far from third base and was picked off by catcher Rene Rivera.

After the Mets tied it on an RBI grounder by Jose Reyes, Chapman launched a drive with two outs in the seventh. Chapman showed pop in the minors, and has homered four times since making his major league debut last month, including a drive Saturday night.

The Athletics made another mistake on the bases in the ninth when Jed Lowrie tried to steal second — with pinch-runner Rajai Davis already there, resulting in an out.

Rookie Daniel Gossett (2-5) gave up two runs and five hits in six innings. He snagged a line drive by Curtis Granderson just above his head in the fifth, preserving Oakland’s one-run lead.
