(SportsNetwork.com) - A pair of clubs swept in their respective series to begin the week square off on Friday night when the Milwaukee Brewers host the Arizona Diamondbacks for the first of three straight contests.

The Brewers come in having lost five straight, including three straight meetings with the San Francisco Giants. They lost Wednesday's finale 3-1 despite a solid outing from Mike Fiers on just three days' rest.

Fiers started in place of Wily Peralta, who went on the disabled list Monday with a strained left oblique, and allowed two runs on eight hits and no walks with six strikeouts over five innings.

Milwaukee, though, fell to an MLB-worst 16-32 on the year.

"We're going through a tough time right now," said Fiers. "But all these guys are battling. We have four months left. There's a lot of time to turn it around."

The Brewers are expected to have shortstop Jean Segura back in the lineup tonight. He landed on the disabled list due to a fractured right pinky finger suffered May 12 on a slide into third base. He is hitting .262 on the year with a pair of homers and 12 RBI.

The Diamondbacks, meanwhile, were in position to salvage the finale of their three-game set with the St. Louis Cardinals on Wednesday, but yielded a pair of runs in the ninth inning for a 4-3 loss.

Brad Ziegler gave up a solo homer to Jason Heyward to begin the frame and even the score, then eventually loaded the bases with one out.

The Diamondbacks set up a five-man infield and Jhonny Peralta hit a grounder that saw Arizona get the forceout at home. However, catcher Jordan Pacheco's wild throw to first allowed the winning run to score.

Pacheco had come into the game earlier to replace Tuffy Gosewisch, who jammed his left knee while trying to beat out a grounder in the sixth. Gosewisch's current status is unknown.

Mark Trumbo hit a home run in Arizona's fourth loss in five games.

"Like I told them after the game, they busted their tails all three games," D- backs manager Chip Hale told his club's website. "I'm proud of them, they played hard, but we lost, so we have to do better."

Taking the mound tonight for the Diamondbacks is Rubby De La Rosa, who is 4-2 on the year with a 4.27 earned run average and will be facing Milwaukee for the first time.

De La Rosa followed up two straight winning starts with a solid no-decision against Miami on May 18, giving up two runs and striking out five over nine innings. He then failed to factor into a 9-6 loss to the Chicago Cubs on Saturday, charged with four runs on four hits and two walks over six innings.

Though the right-hander struck out eight to match a season high, he hit a batter with the bases loaded in the fifth before allowing a bases-clearing double.

Brewers starter Jimmy Nelson struggled with his control last time out and hopes to correct those issues ahead of his first career start against Arizona.

Nelson lost for the third time in four starts with a 2-1 setback in Atlanta on Sunday. He yielded just two runs over 5 2/3 innings, but had to work around five hits and five walks. He had walked four his previous outing as well, a win over Detroit.

The right-hander has lost five of his past six decisions, falling to 2-5 with a 3.67 ERA on the year. He is 1-2 with a 2.83 ERA in four starts at home.

The Diamondbacks have won nine of their past 14 versus the Brewers and are 5-1 in their last six games at Milwaukee.
