Baltimore, MD -- (Sports Network) - Jack Cust tallied two homers and three RBI as the Oakland Athletics topped the Baltimore Orioles, 5-1, at Camden Yards.

The teams were supposed to play a day/night doubleheader but Tropical Storm Hanna caused the first game to be postponed. A makeup date has yet to be determined.

Greg Smith (7-14) scattered three hits and five walks through seven scoreless innings, and Rajai Davis was 2-for-4 with a triple, a run scored and an RBI for the A's, who have won two straight following a four-game skid. Jack Hannahan added a solo home run in the win.

"I felt really good," Smith said. "The five walks doesn't look good. I felt like I actually pitched, got ahead of some hitters and threw strikes. Moving over on the rubber seems to be helping out and I feel really comfortable there."

Daniel Cabrera (8-9) recorded just nine outs in his start, yielding six walks, five hits and two runs in defeat. Nick Markakis drove in the Orioles' lone run in the club's season-high eighth straight setback.

Cabrera was wild right from the start of the game, loading the bases with three straight walks and giving up a run on Cust's sac fly to center.

Cust, who entered Saturday's game leading the AL in walks and strikeouts, led off the third with a blast to right and followed with another solo shot in the fourth -- his 27th homer of the year.

"We've been struggling offensively as a team and anything we can do to score some runs, obviously hitting home runs is a lot easier than trying to manufacture them," Cust said.

Hannahan joined the home run party with his eighth of the year, in the fifth, and Davis tripled in Aaron Cunningham later in the inning for a 5-0 lead.

Huston Street relieved Smith from his superb start in the eighth and was greeted by Lou Montanez's triple and Markakis' run-scoring groundout before getting out of the inning.

Brad Ziegler hurled a scoreless ninth to finish out the game.
