Ivan Nova earned his first victory since May 22 on Sunday, pitching 5 2/3 scoreless innings in the White Sox’s 3-1 win against the Cubs.

Nova snapped his seven-start winless streak. He also earned his victory at Guaranteed Rate Field since Aug. 2, 2015, when he was with the Yankees.

Nova didn’t make a big deal of ending the streak.

“The win depends on everybody,” Nova said. “You can do a good job and not get the win. But it’s good to win.”

Nova allowed five hits and struck out four.

“Right from get-go, we started mixing everything,” Sox catcher James McCann said. “Might be the first time in my career we’ve gone curveball, curveball to start a game, but we knew how aggressive (Cubs leadoff batter Kyle) Schwarber was, how aggressive their entire lineup is and we used that to our advantage.”

Bummer’s plan: Aaron Bummer surrendered a homer to Robel Garcia in the seventh inning Sunday. He bounced back for a scoreless eighth. He had two strikeouts in his two innings.

Bummer has been a reliable arm out of the bullpen for the Sox with a 1.89 ERA. He has pitched 33 1/3 innings in his 28 outings.

“I don’t want to continue to keep doing that with Bummer in terms of having multiple innings to use,” manager Rick Renteria said. “We want to continue to get our other guys to settle in as well, to be able to eat up some of those innings.

“I expect some of the other guys in the back end of our bullpen will start to turn the corner and continue to help us so we don’t put ourselves in the position where I wear those guys out. We monitor everything we do with them, but (Bummer) is showing (he’s) capable of being a multiple-inning guy effectively.”

Palka optioned: Outfielder Daniel Palka was optioned to Triple-A Charlotte after Sunday’s game.

Palka has one hit in 45 at-bats (.022 average) with two RBIs in 17 games during two stints with the Sox this season.

“He’s got to continue to work,” Renteria said. “We brought him back. He was starting to make some strides (with Charlotte). We were hoping it would continue here. Obviously, we faced a lot of lefties over the course of the last two, three weeks.

“We can see there is still some work to get back on track. I’m sure he’s going to do everything he can to do that. As (general manager) Rick (Hahn) tells everybody, be prepared because we do shuffle you guys up and down.”

The Sox will announce a corresponding roster move before Friday’s series opener against the A’s in Oakland.
