You’d think after becoming the first Diamondbacks pitcher in franchise history to face three different Cy Young Award winners in a row that nothing could faze right-hander Matt Koch. Especially after the way things worked out for him.

As big as the names were, it wasn’t as if the Cy-Tri of the Dodgers’ Clayton Kershaw, the Astros’ Justin Verlander and the Nationals’ Max Scherzer outdueled him or anything. The Diamondbacks won two out of three during that stretch and in the lone loss charged to Koch, a 3-1 defeat to Washington, he went eight innings and allowed three runs.

“He is unfazed by any set of circumstances,” Diamondbacks manager Torey Lovullo said Wednesday morning.

Something got to Koch on Wednesday afternoon, though. It was a little-known pitcher and the Milwaukee Brewers, who clubbed four home runs against him in the first four innings en route to an 8-2 victory in front of 16,762 at Chase Field.

With the loss, the Diamondbacks dropped their second straight series after opening the season by going undefeated (10-0-2) in their first 12.

Koch, who had allowed four homers in his previous three starts combined, didn’t make it out of the fifth inning on yet another day when the Diamondbacks’ ice-cold offense stayed ineffective. Arizona managed only one hit off Brewers starter Brandon Woodruff, who was making just his 11th major-league start and entered with a 5.53 career ERA.

“Just a dud, a little bit of a clunker,” Lovullo said afterward. “We didn’t execute on the mound and made some mistakes to a pretty offensive team that is aggressive to certain pitches in certain zones and certain velocities and they made us pay for it.

“… Offensively, we just can’t get clicking. There’s no mystery to it. … but I think in a short period of time you’re going to see us come out of it.”

Woodruff looked every bit the part of an inexperienced big-league pitcher when he walked Diamondbacks catcher Alex Avila, he of the .129 batting average, the first two times he faced him. Other than allowing a first-inning home run to Daniel Descalso, however, Woodruff looked like a Cy Young winner himself.

Of course, the Diamondbacks came into this game with the worst batting average (.222) in baseball. They could manage only four hits overall on Wednesday and, if they don’t find a way to start turning up the offense during their nine-game road trip, they could be in danger of falling out of first place in the National League West.

Don’t assume things are going to get better at the plate just because the Diamondbacks are getting away from Chase Field, where they’ve lost six of their past seven games.

“We’ve still got to put together good at-bats and hit the ball. I don’t think it matters if we’re at home or on the road, we’re struggling,” Descalso said.

The Brewers’ lineup, meanwhile, made Koch squirm in the first two innings. In each, he was one out away from keeping Milwaukee scoreless. But with two outs in the first, Travis Shaw belted a two-run homer off the right-field foul pole. On the next pitch, Domingo Santana deposited a four-seam fastball into the left-field seats.

With two outs in the second, Koch surrendered a base hit up the middle to Lorenzo Cain, which was followed by a two-run homer to right by Christian Yelich. After retiring the side in order in the third, Koch was greeted by a solo shot to center by Tyler Saladino to open the fourth.

About the only thing the Brewers didn’t do was hit a home run into the swimming pool.

“It just wasn’t very good. I wasn’t making pitches when I needed to,” said Koch, whose ERA climbed from 2.43 to 4.06. “The command wasn’t great and my stuff was inconsistent. … I’ve got to keep the ball down.”

As for the offense, the Diamondbacks aren’t running from their failures. After striking out 11 times on Wednesday, they know it’s got to get better.

“We’ve talked about it. I mean, it’s no secret that we’re struggling,” Descalso said. “There’s no sense in shying away from it. … but we’re going to figure it out. It’s not like we’re going to be like this the rest of the season.”

Though his team has dropped 10 of its past 14 overall, Lovullo said he sees no reason to change his course as manager or change his message to the players.

“I don’t change very much,” he said. “I stay pretty consistent and I need them to be, too. I’m not going to change for the sake of wanting to change. I believe in these guys.”
