It took the Cubs a grand total of two pitches to light up the scoreboard on Sunday, and they barely slowed their torrid pace all afternoon.

Dexter Fowler drilled a 1-0 pitch to the left field bleachers, the Cubs tacked on four more homers throughout the game and starting pitcher Jason Hammel picked up a badly needed win as the Cubs rolled over the Braves, 9-3, on a gorgeous afternoon at Wrigley. The win — the Cubs’ 19th in their last 23 games — gave them their fourth four-game series sweep of the season, a feat they hadn’t accomplished since 1945.

In sweeping Atlanta, Hammel improved his record to 7-5 and kept the ball down on a day when the wind was gusting out to left.

“I thought (Hammel) was really sharp, much better command of everything,” Cubs manager Joe Maddon said of his starter, who hadn’t pitched into the seventh inning since July 3. “I know he’s leaving the ballpark today feeling pretty good about himself.”

From a broader perspective though, the Cubs maintained their distance in the wild-card chase thanks to a 3-for-4 effort from Kris Bryant, who had two homers, four runs scored and three RBIs. His first-inning blast to right compounded the damage already done by Fowler. The Pirates, now up 2 1/2 games over the Cubs, host the Giants on Sunday night. The Giants currently trail the Cubs by 5 1/2 games for the second NL wild-card spot.

“Sometimes you get the wind blowing out and you get it in the basket, sometimes it doesn’t even get to the outfield,” Bryant said. “It was a good day to hit. (Opposite field), that’s more the swing I like. I like to hit balls to right field. That (first-inning) pitch was actually inside so that’s even more encouraging for me.”

The victory also moved the Cubs (71-51) to a season-high 20 games over .500 and improved their home record to 38-26. Following Monday’s make-up game against Cleveland, the Cubs will have spent their last 19 days in the Windy City before heading to California.

Maddon spoke pregame about how Chicago was a destination city that opposing teams circle on their road trips.

“I think teams do feel a certain amount of energy by being here, the opposition,” he said, before recalibrating. “At the end of the day we come here and we have to feed of off our fans, and I think we’re doing that right now. I still believe it’s a tremendous home-field advantage.”
