DENVER — You don’t go 18-61 by accident.

The Dodgers scored six runs in the fourth inning, aided and abetted by the Colorado Rockies’ shortcomings, but had to hold on until the end of a 9-7 victory on Tuesday night at Coors Field.

The signature moment in this installment of a historically bad season for the Rockies came during that fourth inning.

Rockies first baseman Michael Toglia made two errors in the inning and a third defensive blunder — a poor throw home that went as a fielder’s choice rather than an error.

Toglia’s second error, though, managed to bring Rockies starter German Marquez to the ground. The right-hander apparently rolled his ankle watching Toglia misplay the grounder, making his move to cover first base a wasted effort.

The Rockies went into that inning leading 2-0, Marquez having retired nine of the first 11 Dodgers batters.

But Toglia (who had three doubles on the other side of the ball) whiffed on Freddie Freeman’s ground ball to start the fourth inning. Back-to-back singles by Will Smith and Max Muncy loaded the bases. One run scored on a ground out, another on Toglia’s ill-advised decision to throw home on another ground ball.

That brought up Michael Conforto, who had doubled in his first at-bat. He golfed a Marquez curveball 420 feet down the right-field line for a three-run home run. It was Conforto’s first multi-hit game since May 27, his first game with more than one extra-base hit since May 13 and his first multi-RBI game in 69 games as a Dodger.

With his .165 batting average, just two hits in his previous 23 at-bats and playing time slowly slipping to Hyeseong Kim – nobody needed a visit to Coors Field more than Conforto.

“Had some good games here and there, but just to put a run of some solid games together has been the thing that I’ve been missing to kind of get on a roll,” he said. “That’s what we’ve been working towards. Making adjustments, trying to make sure that I’m able to be consistent out there and have good day after good day after good day and keep helping the team.

“Sometimes, just seeing a ball fall in there, finding a hole. The mental side of the game is a big part of it, and sometimes you just need to see something go your way.”

The clock has been ticking on Conforto’s time to do that. With the trade deadline just over a month away, the Dodgers could look to replace him or add in a way that would diminish his role.

“It’s critical,” Dodgers manager Dave Roberts said of the next month for Conforto. “I think that I’ve shown my faith in him and giving him opportunities. I do, like I’ve said, think he’s trending in the right direction. But we’re going to continue to look and figure out ways we can get better as a ballclub as we do get closer to the deadline. I hope that’s not in his kind of mindset. Just continue to get better each night. But it’s important for him to continue playing well.”

Mookie Betts wasn’t far behind Conforto in needing to see some positive results. Betts emerged from a 6-for-37 slide with his first multi-hit game since June 7 in St. Louis (including an RBI double in the six-run fourth).

“I’ve had a couple good games and then a week’s worth of bad games,” Betts said of Tuesday being the sign of a turnaround. “I’m trying to figure it out. I’m doing my best to try and figure it out. I just make sure I continue to play defense, do what I can to help the boys win.”

Shohei Ohtani piled on with a two-run home run in the sixth inning. It was his 27th home run of the season, tops in the National League, and the 300th of his professional career, Japan and MLB combined.

That should have been more than enough for the pitching collective the Dodgers used to stitch together nine innings. Left-hander Justin Wrobleski was the biggest piece, following Jack Dreyer’s one inning with five effective innings of his own.

Wrobleski allowed two runs on five hits while striking out a career-high seven with a fastball trending up in velocity. He averaged 95.3 mph Tuesday (topping out at 99.5 mph), a 1.3 mph bump from his previous season average. He got seven of his 14 swings-and-misses with the fastball.

“I think part of it is effort for me,” Wrobleski said of the velocity increase. “Then part of it is just some mechanical adjustments that I made in trying to get a little more direction towards home. Coming set a little wider, kind of rocking back a little more into my back leg and trying to create a little more linear momentum towards home. I think it’s just a combination of effort and I’m feeling good and a couple things that are syncing up right now.”

Wrobleski has settled into this ‘bulk’ role. In eight starts over two seasons, he has a 7.62 ERA (including 12 runs over 11 innings in his two starts with the Dodgers this season). But he has allowed just four earned runs in 24 1/3 innings when pitching out of the bullpen.

“I don’t think there’s a lot to that, in my opinion,” said Wrobleski -- who will pitch in this role again next Sunday, according to Roberts. “Any time you come up, it’s going to be an adjustment. I’ve had to make adjustments on the fly up here and I’ve had a couple really bad starts that have made my numbers probably look worse. I didn’t pitch well in Washington. I gave up eight runs so, yeah, my starting numbers are going to look bad. But for me it’s just treating it the same as a start. Just trying to do my job and continue to eat innings.”

Things got Coors-y after Wrobleski left the scene. The Rockies scored once in the seventh inning off Kirby Yates then three times in the eighth off Anthony Banda and Tanner Scott, briefly making it a one-run game, 8-7.

Teoscar Hernandez opened it up a little with an RBI double in the top of the ninth but the Rockies still got the tying run to the plate before Scott closed it out in the bottom of the ninth.
