With Kyle Lohse looking to win his sixth straight start against the Rockies, the Brewers will try to improve to 5-0 in the season series Friday night.Last weekend, Milwaukee (49-32) batted .322 and hit six homers while scoring 28 runs and pounding out 38 hits during a three-game sweep at Colorado. Third baseman Aramis Ramirez went 8 for 13 with two doubles, two homers and six RBIs at Coors Field, then was 2 for 3 with a two-run homer in Thursday's 7-4 win over Colorado (35-44).The Brewers' NL-leading record is the best in team history through 81 games. With 14 games remaining before the All-Star break, the club is closing in on the team record of 54 wins before the Midsummer Classic."It's halfway of the season? It doesn't feel like it yet," reliever Brandon Kintzler told MLB's official website. "I'll take another 49 (wins)."Outscored 25-7 during a four-game road slide, the Rockies have dropped nine of 10 overall.Lohse (9-2, 3.20 ERA) allowed three runs, seven hits and three walks in five innings of a 6-5 win in Denver on Sunday, but improved to 5-0 with a 3.11 ERA in his last six starts against the Rockies.Lohse is 3-0 with a 1.93 ERA in his last five home starts and makes his first at Miller Park since tossing a three-hitter in a 9-0 rout of the Chicago Cubs on June 1. Since then, the right-hander is 2-1 with a 5.25 ERA in four road outings.Colorado's Tyler Matzek (1-2, 5.19) also squared off against Lohse on Sunday, giving up five runs, seven hits and four walks over 5 1/3 innings of his third major league outing."They're a good-hitting team," the left-hander said. "I just tried to pound the zone and just kept leaving it up."Ramirez went 2 for 3 with a double and a two-run home run against Matzek.Colorado's Ryan Wheeler hit a fourth-inning grand slam Thursday to give Colorado a 4-3 lead, but that proved to be the only offense the Rockies could muster. The little-used third baseman is 4 for 9 with six RBIs in his last three games after batting going 5 for 24 with a homer and six RBIs in his first 20.Teammate Justin Morneau is batting .411 in his last 14 games, and is 12 for 25 in his last six against the Brewers.Though left-handed hitting Milwaukee second baseman Scooter Gennett ranks among the top offensive players at that position with a .311 average, six homers and 27 RBIs, veteran Rickie Weeks could start a second straight game with another lefty on the mound. Gennett is hitting just .129 (4 for 31) against left-handers.Weeks had three hits Thursday, including a leadoff homer."You've got to do what you've got to do. I'm a professional, so you've got to do your job and be ready and go out there and perform," said Weeks, who is batting .276 with three home runs and 15 RBIs in 61 games.He went 1 for 3 against Matzek last weekend.
