SCOTTSDALE, Ariz. -- Micah Owings has been working at a side job this spring while trying to pitch his way onto Arizona's 25-man roster. He's been working out at first base and taking a little batting practice.
"He should really feel good about the way he threw," Diamondbacks manager Kirk Gibson said. "We want to get him pitching and throwing the ball properly. I will have to get him an at bat pretty soon."
When he's not working out with the pitchers, Owings is off at a back field taking grounders. The .293 career hitter has nine home runs in 184 career at bats.
Jonathan Sanchez threw three solid innings, allowing two runs -- one earned -- on four hits. He walked one and struck out three.
"I thought Johnny threw the ball well," Giants manager Bruce Bochy said. "He had good stuff all night."
Zach Duke allowed three runs on seven hits over two innings and has given up 13 hits in his four innings this spring.
"The main thing is I felt good," Duke said. "You can't do too much about six broken bat hits. I'll just continue to work hard and get better. The more work I get, the more refined I'll get."
Gibson echoed his starting pitcher.
"He has a long way to go but he's healthy," he said. "He broke some bats and that's a good sign."
Freddy Sanchez collected his first two hits of the spring and Chris Stewart had two hits and drove in two runs for the Giants, who have won two of their last three games. Aaron Rowand and Charlie Culberson also drove in runs.
Stewart tripled home two runs in the second inning and scored on Rowand's sacrifice fly, offsetting Montero's RBI single in the top of the frame.
Branyan singled home a run in the third as the Diamondbacks closed to within 3-2.
Stewart and Culberson hit back-to-back doubles in the sixth to make it 4-2.
"Stew put on quite a hitting show," Bochy said. "Freddy looks like he's swinging the bat well."
Marc Kroon, the 37-year-old closer who spent most of his career pitching in Japan, earned his first save on American soil with a scoreless ninth.
"He was pretty excited," Bochy said. "He kept the game for his first save in the USA."
