Highly touted Milwaukee prospect Aaron Ashby got roughed up for seven runs in the first inning of his big league debut, but Luis Urias homered twice as the Brewers rallied to rout the Chicago Cubs 15-7 Wednesday for their eighth straight win.

The Brewers swept the three-game series and increased their NL Central lead to six games over Chicago. The Cubs lost their sixth in a row.

Willy Adames hit a grand slam during an eight-run burst in the fourth inning that put Milwaukee ahead 14-7. His error at shortstop helped the Cubs break loose at the start against Ashby.

The Angels also rallied to win Wednesday after allowing seven runs in the first inning to the Yankees, making it the first day since at least 1900 when two teams allowed seven or more runs in the first inning and rallied to win, according to STATS.

The 23-year-old Ashby was charged with seven runs, four of them earned, on four hits and three walks. Of his 39 pitches, only 18 were strikes.

Willson Contreras led off the game with a single and the Cubs loaded the bases with no outs. Javier Baez hit a two-run single, Adames' misplay let another run score and bunt single produced a run.

After a double steal, a run-scoring wild pitch and two walks, Ashby exited with the bases loaded, two outs and trailing 5-0. Miguel Sanchez relieved and gave up a two-run single to Patrick Wisdom.

Five Brewers relievers combined for 8 1/3 scoreless innings. Trevor Richards (3-0) wound up with the win.

Urias had his first multi-homer game in the majors and finished with three hits and four RBIs.

Jace Peterson drove in three runs with a pair of singles.

Slumping outfielder Jackie Bradley Jr. had his second multi-hit game in the series and just his fifth of the season.

Milwaukee tries to continue its winning streak behind RHP Corbin Burnes (3-4, 2.53 ERA), who gets the start in the first of a four-game series against the Pirates in Pittsburgh. Burnes got a no-decision his last time out despite holding the Rockies to a run over six innings. He's 3-0 with a 3.19 ERA in 15 career games against Pittsburgh.
