PHOENIX -- Jackson Chourio gave the Brewers a two-run lead in the bottom of the 10th inning, putting Milwaukee just three outs away from sweeping the D-backs.

The bullpen, however, remained inactive. Two-time All-Star closer Devin Williams wasn’t getting loose with the game in the line. Instead, Jared Koenig returned to close out the game after working the ninth inning.

Koenig failed to record an out, loading the bases and allowing a long walk-off single to Eugenio Suárez, as the Brewers lost, 11-10, to the D-backs on Sunday evening under the roof at Chase Field.

Williams was warming up in the bullpen in the ninth inning and said that he was ready to come into the game if the Brewers were able to hang on to their one-run lead in the eighth inning. The 29-year-old noted he wasn’t at100 percent, but told his coaching staff he was available.

Brewers manager Pat Murphy looked at the big picture. If Williams took the bump, he would have pitched in four of the past six games. With the Brewers in the thick of a 13-game stretch with no off-days, he wanted to err on the side of caution.

“It was a consensus decision,” Murphy said. “... If we brought Devin in for one hitter, a specific hitter, or something like that, we could have done it with two outs.

“He was available, but not for any extended period. So if you put him in the game with no outs or something like that, then potentially, he's gone through a high number of pitches and [then] he's not available.”

Williams said he “understands the decisions that were made,” and when asked if he appreciated the Brewers looking out for his health in the long run, the right-hander responded, “I mean, what's good for me is good for them, right?”

The Brewers failed to sweep the D-backs, but were still able to leave the desert by taking two games from the club that eliminated them from the National League Wild Card round last year, and ultimately became NL champions. With the loss and a Cubs win, Milwaukee's magic number for clinching the NL Central remains at three.

The good news is that the Brewers have a chance to celebrate winning their third division title in the past four seasons at American Family Field, as they begin a seven-game homestand that begins Monday night against the Phillies.

But there may be some bad news looming for the bullpen. Joel Payamps entered the game in the seventh inning with a one-run lead and two outs. He only needed five pitches to retire Ketel Marte and according to Murphy was set to return in the eighth inning.

However, Payamps informed pitching Chris Hook that he was experiencing tightness in his forearm. Trevor Megill pitched instead and ended up giving up a game-tying sacrifice fly to Suárez. Murphy said that Payamps’ injury “changed everything.”

“We can't just tear this bullpen up and have nobody to pitch for the next two days,” Murphy added.

The game ended in a nail-biter, but early on it seemed like the D-backs were going to run away with it. Arizona scored five runs off DL Hall, who had been pitching out of the bullpen in his past two appearances -- and knocked him out of the game after three innings.

Willy Adames went on to give the D-backs a 7-5 lead three batters later by doubling in Brice Turang and Chourio. It was the 29-year-old shortstop’s 108th and 109th RBIs of the season, putting him just four short of tying Hall of Famer Robin Yount’s franchise record for a shortstop (set in 1982).

It displayed the heart and soul that the club has proven all season. Earlier in the series, Murphy said that this tough stretch to close out the season includes the Phillies, D-backs, Pirates and Mets comes at a great time and is motivating, especially with the playoffs on the horizon for this club.

“We’ve been doing it all year,” Murphy said. “They compete all year. That's why you gotta have enough bodies to compete day in and day out. But today we took a chance, and it didn’t work out. And that’s a credit to the Diamondbacks.”
