"All of it feeds off fastball command," Moore said. "That's kind of the glue that holds everything together, just being able to throw the fastball in and out, especially early in the count for strikes. You have the option to branch out and pitch yourself into different situations from that."
Moore is 4-0 with an ERA of 1.16 in his last five starts, and has allowed just four runs during that span. Since June 1 he's 9-2 with a 2.79 ERA.
Moore will look to continue that pace on Friday as the Rays continue their series with the A's at Tropicana Field.
In his previous outing, against the Angels on Sunday, Moore went 6 2/3 innings, allowing just two runs on five hits for his 10th win of the season. He struck out five and walked two.
Jarrod Parker will take the mound for Oakland, ready to build off his most recent outing, against the Indians on Sunday. The right-hander snapped his three-game losing streak by tossing eight shutout innings, allowing just six hits en route to his eighth win of the season.
Parker has not allowed a home run in his last four starts, and he has surrendered just six in 129 1/3 innings this season, an average of 0.42 per nine innings. That's the lowest number in the American League and second lowest in the Majors.
Parker said that the difference on Sunday was his ability to locate his pitches.
"I had to get out of some jams, and I was able to keep the same rhythm," Parker said. "I was able to throw a lot of two-seamers down in the zone and kept the ball on the ground."
A's: Pennington adjusting to second
Having shifted to second base after the arrival of shortstop Stephen Drew, Cliff Pennington made his second straight start there on Thursday against the Rays at Tropicana Field.
Before Wednesday, Pennington had made each of his previous 439 starts at shortstop.
"Based on the amount of shifts we have, he's over there working on double plays sometimes, anyway, during the course of the season," manager Bob Melvin said. "It's not going to be a problem for him. It's just the different angles he has to deal with and getting used to those. But he's a good athlete and plays the middle of the diamond, so ... we feel like the learning curve will be shorter than longer for him."
Rays: Longoria ready for regular action at third
Although Evan Longoria would like to be at third base every day, he knows he has to be patient.
Longoria, who came off the disabled list on Aug. 7, played third base on Tuesday and Thursday. Before that he had been used exclusively as the designated hitter.
According to manager Joe Maddon, Longoria will play every other day at third base for the remainder of the team's homestand.
"Whatever he says," Longoria said. "We haven't really talked one-on-one about it. I know that it's kind of an issue that [the coaches and front office] have been talking about as far as matchups, situations, keeping me fresh and all that. But my legs have felt good. That's the most important thing."
Oakland right-hander A.J. Griffin (shoulder) made his first rehab start with Triple-A Sacramento on Wednesday, giving up three runs on four hits, with three walks and four strikeouts in just 2 1/3 innings. He threw 60 pitches, 34 for strikes.
