run home run and Prince Fielder homered in a six-run fifth inning as Milwaukee rallied to beat St. Louis 9-6 Sunday in Game One of the National League Championship Series. Yuniesky Betancourt also homered in the fifth for the Brewers, who won all three games at home in their opening round playoff series against Arizona. Braun launched a towering 463-foot home run in the first inning and added a two-run double to finish with four RBIs. Fielder's fifth-inning homer accounted for two runs, and Betancourt finished off the rally with a two-run home run of his own for the Brewers, who were facing the Cardinals in the playoffs for the first time since the 1982 World Series. “That was a nice inning there,” Brewers manager Ron Roenicke said. “It was nice Brauny, in the first inning with the two-run homer. But to score like we did there, yeah, that's outstanding.” Milwaukee starting pitcher Zack Greinke, who was 11-0 during the regular season, gave up six runs on eight hits over six-plus innings. David Freese blasted a three-run home run in the fourth inning for St. Louis, who are in the Major League Baseball playoff semifinals for the 10th time in franchise history. Jonathan Lucroy hit an RBI single off pitcher Kyle McClellan in the seventh to give Milwaukee a 9-6 lead. Francisco Rodriguez pitched a scoreless eighth and John Axford threw a perfect ninth inning to help seal the Brewer's win. The winner of the best-of-seven series will take on the American League champions in the World Series. Game two is scheduled for Monday with St. Louis' pitcher Edwin Jackson going up against Milwaukee's ace Shaun Marcum. “We'll come back out,” Cardinals star Lance Berkman said. “The same thing happened to us in the first game against Philly. We were able to regroup.” Rangers vs. Tigers put off Game two of the American League Championship Series between the Texas Rangers and Detroit Tigers was postponed Sunday because of rain. The contest between the teams battling for a World Series berth in the second round of the Major League Baseball playoffs was rescheduled for Monday. That means the teams will lose their dedicated travel day with the best-of-seven series scheduled to resume when Detroit hosts Game Three Tuesday. The Rangers beat Detroit 3-2 in Saturday night's opener, a game in which two fifth-inning rain delays lasted nearly two hours total.
