PHOENIX -- With each outing, you can almost see the confidence growing inside of Luke Weaver.

The D-backs right-hander continues to get better with each start this year, and that was on display again on Thursday in Arizona’s 3-2 win in 10 innings against the Braves at Chase Field.

Weaver, who was acquired from the Cardinals in the Paul Goldschmidt trade, has searched for a third pitch to go with his fastball and changeup, and this year he seems to have found it in a cut fastball.

Weaver allowed just one run and fanned six over seven innings, and had to settle for watching David Peralta’s ninth-inning game-tying homer on the television in the D-backs' clubhouse.

In fact, Weaver might have known before anyone in the dugout that Peralta had a chance to hit that hanging Luke Jackson breaking ball.

“Saw the hanger and in that split second was hoping that he was going to ride back and send it to right,” Weaver said. “And that was a pretty cool swing and just a cool moment.”

Since allowing five runs (four earned) in his first start of the year, Weaver has not allowed more than three runs in a game in the seven outings since. Over his last five starts, he’s been even better, compiling a 1.85 ERA.

“He’s just really dialed in and on the attack,” D-backs manager Torey Lovullo said. “And I can just tell by his mound presence, and his demeanor -- he wants the ball back from the catcher as soon as possible so he can go to work. He’s just in a really good run right now.”

The Braves got their lone run off him in the third, but after that he made a mechanical adjustment, syncing up his top half with his lower half, and he went on to retire 13 of the final 14 batters he faced.

“It was just simple mechanics,” Weaver said. “The game was speeding up on me a little bit, and what I felt like I was doing right was just a little bit of slowing the game down, letting everything work together, syncing it back up. I felt like I was kind of getting into a better groove, and making some pitches and throwing pitches where I needed to. I don’t want any of this about me because we won that game because of our defense.”

Oh yes, the defense.

Right fielder Adam Jones robbed Ronald Acuna of a home run in the sixth when he reached over the right-field wall. Jones also made a nice play on Brian McCann’s liner to the wall in the seventh, and Peralta made a diving catch in left to rob Nick Markakis earlier in the inning.

“They got me where I needed to be, especially late in the game, when the pitch count is going up in a close one-run game, so hat tip to them,” Weaver said.

The D-backs won the game in the 10th when, with runners on the corners, Ketel Marte fought off an inside pitch from A.J. Minter and blooped a single to right that fell between second baseman Ozzie Albies and right fielder Markakis.

“I was just trying to make contact,” Marte said. “I just tried to put the ball in play. He threw me a fastball up and in and I just pulled my hands inside and got the base hit.”

Did he think he had a hit when it left his bat?

“I just figured he was going to catch it,” Marte said with a smile. “But he didn’t catch it, and they gave me a base hit.”
