The Brewers look to improve to 7-0 at Miller Park in Greinke's starts when they continue a four-game set Friday night against the Cincinnati Reds .
Milwaukee (47-42) won for the third time in 10 meetings with Cincinnati (44-45) by holding on for a 5-4 victory Thursday. The Brewers are a major league-best 31-13 at home.
They haven't lost at Miller Park behind Greinke (7-3, 5.66 ERA), who is 5-0 despite a 4.26 ERA in those six starts. He's recorded 52 strikeouts and two walks in those outings.
The right-hander is coming off two straight shaky road performances. He gave up seven runs over two innings in a 12-2 loss to the Yankees on June 28, then allowed five runs in six innings Sunday in Milwaukee's 9-7 loss at Minnesota.
"I keep making bad pitches at the most important times," Greinke said. "I've got to figure out how to stop doing that. It's upsetting."
Greinke has won both of his career starts against the Reds with 18 strikeouts over 15 innings. The lone meeting this season was a 7-2 road win May 31 in which he yielded two runs over six innings.
The Brewers are unsure when All-Star left fielder Ryan Braun will play again. Braun missed his fifth straight game Thursday, although tests showed no damage to his strained left calf.
Braun is hitting .320 with 16 homers, 62 RBIs and 19 stolen bases in 83 games. He's also carrying a career-high 22-game hitting streak, his third double-digit hitting streak of the season and the third-longest in franchise history.
"Not much news to report. Slowly progressing, moving in the right direction," Braun said Thursday. "I don't want to be stupid about it. The last thing I want to do is rush back."
Milwaukee was well aware of its previous problems against Cincinnati.
"We've had a tough time at their place and at our place when they came here, too, so it's nice to get the first game of the series and hopefully we can carry it over the next three days into the break," said closer John Axford , who recorded his 23rd save.
The Reds lost for the fifth time in seven games, going 2 for 13 with runners in scoring position. Votto and Phillips each had two hits as Cincinnati finished with 12.
Cincinnati's Mike Leake (8-4, 4.03) seeks a third straight win after he allowed four runs over six innings Sunday in a 7-5 victory over Cleveland. He's won his last three road outings, posting 14 consecutive scoreless innings in the last two.
The right-hander has no decisions and a 3.46 ERA in two starts against Milwaukee this year. Yuniesky Betancourt is 4 for 5 against Leake in those games, while Weeks has gone 3 for 6 with a triple and a homer.
