No sweep for you, Rockies.

Veteran Chicago right-hander Kyle Hendricks, first baseman Michael Busch, and a bushel of Colorado walks ensured that on a late-summer Sunday at Coors Field.

In front of 40,706 fans, many clad in Cubbies blue, Hendricks pitched six innings of one-run ball and then got stellar bullpen support in a 6-2 Chicago victory. Busch chipped in with two solo homers, the first multi-homer game of his career.

The Rockies flopped on the mound and at the plate. They walked 12 batters — tying a franchise hit — and managed just four hits.

Starter Cal Quantrill, back from a two-week stint on the injured list where he dealt with right triceps inflammation, had an awful outing. The right-hander walked a career-high six and gave up four hits in just 2 1/3 innings.

“I was a little rusty, and I just wasn’t competitive today. I wasn’t good,” said Quantrill, adding that his arm felt fine.

Regarding all of the freebies dolled out by Rockies pitchers, manager Bud Black said: “The Cubs do a decent job of controlling the strike zone and they have some guys who draw walks. They do a good job with two strikes, and you saw some of that today. … And a couple of guys that we saw today, kind of have a walk in their game.”

The Rockies slipped to 57-93. They must finish the season 6-6 in their final 12 games to avoid a second straight 100-loss season. Colorado lost 103 games last year.

Chicago put an exclamation point on its victory with a three-run ninth off erratic reliever Justin Lawrence, who served up a solo homer to Busch and a two-run homer to Pete Crow-Armstrong. Lawrence, whose ERA rose to 6.04, walked three in the frame.

The Rockies have only two sweeps this season but have been playing solid baseball lately, particularly at home. Not on Sunday.

Hendricks entered the game with a 3-11 record and bloated 6.51 ERA. But he baffled Colorado for six innings, striking out seven. His lone mistake was serving up a leadoff homer to catcher Jacob Stallings in the third. Stallings swatted a 1-0 changeup 419 feet and into the left-field bleachers for his career-high ninth homer.

Hendricks improved his ERA to 3.28 in six career starts at Coors Field and became the first Cubs pitcher in history to pitch at least six innings while allowing two or fewer hits and one or fewer runs in a start at Coors.

“It’s tantalizing (stuff) because you don’t see that type of pitcher, really at all anymore,” Black said. “He’s a true craftsman. The fastball moves to all four quadrants, he’s got a feel for the change, he’s got a slow breaking ball.

“There’s a big variance with his breaking ball. … His pitches are moving and he’s got great feel and great instincts.”

Quantrill, who was no match for Hendricks, didn’t make any excuses.

“I’m ready to come out and pitch and execute the way I wanted to,” he said. “I just didn’t. I was having a hard time adjusting and figuring it out. Obviously, you can’t do that if you want to give your team a chance to win.”

But the Rockies managed to stay in the game, thanks, in large part, to the work of reliever Jeff Criswell, who bailed Quantrill out of a one-out, bases-loaded jam in the third. Crisell struck out a season-high six batters, the most for a Rockies reliever this season, over a season-high 2 2/3 innings.

The Cubs took a 2-0 lead in that third inning, the big hit a two-run single by Busch.

Chicago’s lead grew to 3-1 in the seventh on Busch’s one-out homer down the right-field line off Jake Bird. Busch’s 19th homer traveled 438 feet.
