MILWAUKEE (AP) – Nyjer Morgan hit a go-ahead, three-run double and the surging Milwaukee Brewers scored five runs in the fifth inning off Cardinals ace Chris Carpenter to rally for a 6-2 win over St. Louis on Monday night and extend their season-best winning streak to seven. Milwaukee (61-49) moved 3 1-2 games ahead of St. Louis in the NL Central, its biggest lead of the season. The Brewers and Cardinals will play 11 more times this year. Zack Greinke (9-4) allowed a first-inning, two-run homer to Matt Holliday, but the Brewers offense prevailed again in the second matchup this season of the former Cy Young winners. The Brewers’ first six batters reached base in the fifth, with Morgan delivering the decisive hit. Carpenter (6-8) appeared in complete control until the fifth when he had a 2-0 lead.
