PITTSBURGH (AP) — A.J. Burnett entered his start Monday on a four-game winning streak with a chance to extend it against the Milwaukee Brewers, owners of baseball's worst record.

Burnett gave up one run in seven innings and pitched through a rain delay in a game that was ultimately delayed more than two hours. But the only run he allowed was the only run the Brewers needed when they scored in the fifth following the first delay.

"It's as efficient and effective as I've ever seen him through four innings," manager Clint Hurdle said. "I don't know whether the rain had anything to do with it or the delay had anything to do with it."

Jimmy Nelson did Burnett one better as he pitched six shutout innings to lead the Brewers to a 2-0 victory Monday night.

Burnett (6-2) yielded one run and five hits in seven innings. He walked one and struck out six.

The game was delayed for 28 minutes in the home fourth then again for one hour and 45 minutes at the beginning of the eighth inning. The delays totaled two hours and 13 minutes.

Aramis Ramirez singled leading off the fifth and moved to third on Gerardo Parra's double. Jean Segura drove Ramirez home with a groundout to short for a 1-0 Milwaukee lead.

Burnett said he felt good throughout the entire time and didn't blame the delay for the only run he allowed.

"That has nothing to do with it," Burnett said. "The pitch wasn't exactly where I wanted it but that's no excuse."

Milwaukee scored again after the second rain delay. Ryan Braun fought through a 12-pitch at-bat against Pittsburgh left-hander Antonio Bastardo to drive Carlos Gomez home with a single to right.

The Brewers scored both of its runs in each of its at-bats following the game's delays. Hurdle attributed it to coincidence.

Nelson (3-6) gave up four hits and walked three. He struck out seven.

Milwaukee manager Craig Counsell knew the game would be delayed at some point due to the unfavorable weather forecasts.

"I was just happy the first delay was short enough where we could leave Jimmy out there and he gave us six great innings," Counsell said. "He was locked in from the start."

Pittsburgh was poised to get on the board in the third when Francisco Cervelli singled then moved to third on Jordy Mercer's single. But Nelson induced two groundouts and recorded a strikeout to escape unscathed.

"We get in jams and he got better," Counsell said. "He took control of those situations and he got better in those situations."

The Pirates went 0-for-10 with runners in scoring position and stranded nine men on base.

Francisco Rodriguez worked a scoreless ninth for his 11th save.

NEW MAN IN TOWN

Pittsburgh selected Arizona shortstop Kevin Newman with the No. 19-overall pick in the first round of Monday's Draft. Newman was a First Team Pac-12 selection this season and hit .370 in 55 games.

The Pirates drafted a shortstop with their first-round pick for the second time in as many drafts after they picked prep prospect Cole Tucker last year.

"We liked Kevin a lot with this spot in the draft," general manager Neal Huntington said. "Best available player and a guy that we like a lot, and are thrilled with the opportunity to add him to the system."

UP NEXT

Brewers: RHP Taylor Jungmann makes his major-league debut as the Brewers continue their three-game series in Pittsburgh. Jungmann is 2-3 with a 6.37 ERA in nine starts for Triple-A Colorado Springs.

Pirates: LHP Francisco Liriano (3-4, 3.24 ERA) looks to win his fourth consecutive start Tuesday. Liriano has struck out 29 batters over his last 19 innings pitched and never lost to Milwaukee at PNC Park as a member of the Pirates.

TRAINER'S ROOM

Pirates: CF Andrew McCutchen received a scheduled day off Monday. Manager Clint Hurdle said McCutchen's knee was "a little sore" after Sunday's game and wants to take advantage of Thursday's off-day to give McCutchen an extra day off. ... RHP Jameson Taillon threw 47 pitches over four innings in extended spring training Monday. Taillon, the No. 2 pick in the 2010 Draft, continues rehabilitation from Tommy John surgery last April.
