Peralta is designated for assignment.

The Wily Peralta experiment has reached the end of the line.

A little more than two months after moving Peralta from the starting rotation to the bullpen, the Milwaukee Brewers designated the right-hander for assignment.

To replace Peralta on the 25-man roster, the team selected the contract of outfielder Kirk Nieuwenhuis from Class AAA Colorado Springs.

“I think really we’re just trying to get more productive there and Wily had been struggling,” manager Craig Counsell said prior to the Brewers’ game against the Chicago Cubs at Miller Park on Saturday.

“Unfortunately, we weren’t able to right the ship and get him on track. So, we thought it was time to make a move.”

Peralta, 28, was once considered a rising star in the organization – a fireballer capable of blowing away hitters as well as generating a high percentage of ground-ball outs with his sinking fastball.

He had a breakout season in 2014, going 17-11 with a 3.53 earned run average in 32 starts before injuries and inconsistency derailed his progress.

Peralta went 5-10 with a 4.72 ERA in 20 starts in 2015. He was named the Brewers’ opening-day starter in 2016 but struggled so much early he was optioned down to Colorado Springs.

Peralta returned to the Brewers at the start of August and closed the season strong, raising hopes he could get himself back on track in 2017. Instead, he was switched to the bullpen after making eight starts and then suffered a strained right calf that landed him on the disabled list for a month.

He was reinstated last Sunday and pitched twice, with his last outing qualifying as a complete disaster.

He allowed eight hits, seven earned runs and two walks over 1 2/3 innings in an eventual 15-2 loss at Washington.

Peralta departs with a 5-4 record, 7.85 ERA and WHIP of 1.83. In 11 total relief appearances, he was 1-2 with an 11.94 ERA and WHIP of 2.48.

While Peralta was actually averaging a careerbest 96.6 mph on his fastball, it just wasn’t resulting in enough outs.

“I think velocity is the easy thing we always point to, but it just wasn’t working,” Counsell said. “He wasn’t getting hitters out. The guy that pitched last night (Brent Suter) that doesn’t have velocity was getting hitters out.”

With Peralta playing on a one-year, $4.275 million contract, it’s unlikely he’d be claimed off waivers by another team. He’d also forfeit the remaining portion of his salary if he refused the assignment, so there’s a chance Peralta could wind up staying with the organization and finishing out the year at Colorado Springs.

Nieuwenhuis broke spring training with the Brewers but hit just .080 with one home run in 15 games before being designated for assignment.

He hit .221 with four homers and 25 RBI over 65 games at Colorado Springs.
