MILWAUKEE (AP) _ Todd Helton doubled twice and drove in three runs as the Colorado Rockies defeated the Milwaukee Brewers 8-6 Friday night for their sixth straight win.

With every other team in the majors involved in interleague play, the Rockies and Brewers met in an NL game.

Helton, who hit .512 in May, was 2-for-5, giving him 15 hits in his last 21 at-bats with four doubles, four homers and 12 RBIs.

Helton, leading the majors in hitting at .420, doubled to key a seven-run fourth inning.

Jeff Cirillo, traded from Milwaukee to the Rockies last December, singled twice and walked three times in his return to County Stadium.

Winner Rolando Arrojo (3-4) struggled through five innings, allowing six runs on seven hits with three walks. Mike Myers got three outs for his first save.

Colorado erased a 3-0 deficit by scoring seven times in the fourth, helped by four walks, an error and a wild pitch.

Jason Bere (3-4) escaped bases-loaded, one-out jams in the first and third innings. He was not so fortunate in the fourth.

The Rockies loaded the bases with two outs, and a walk to Cirillo made it 3-1. Helton greeted reliever Steve Woodard with a two-run, ground-rule double down the left-field line to tie it at 3.

Shortstop Luis Lopez was charged with an error when he failed to make a throw on Jeffrey Hammonds' grounder, allowing Cirillo to score from third.

After a walk to Brent Mayne, Brian Hunter followed with a two-run single and Neifi Perez added an RBI single for a 7-3 lead.

Helton's RBI double in the fifth made it 8-3, but Milwaukee bunched five hits for three runs in the bottom half.

Milwaukee took a 1-0 lead in the first when Ron Belliard led off with a triple and scored on Jeremy Burnitz's grounder to short.

Notes: Brewers shortstop Mark Loretta left in the second inning with a bruised left foot. He fouled a pitch off his foot in his first at-bat and took the field in the top of the second, but left after one out, limping noticeably. He is listed as day-to-day. ... Bere threw 110 pitches in 3 2-3 innings, walking six. ... Belliard matched his career high with four hits.
