Los Angeles welcomes the newest addition to its starting rotation Friday when the Dodgers begin a three-game series against the host Milwaukee Brewers in a battle of division leaders. Roberto Hernandez takes the mound for Los Angeles, which acquired the veteran from Philadelphia on Thursday to replace Josh Beckett, who could miss the rest of the season with a left hip impingement. "Obviously, it's a nice feeling going to a team that has a chance," Hernandez told reporters. "I wasn't expecting this. So yeah, I'm excited, but at the same time, I'm nervous."The Dodgers moved 3 1/2 games ahead of San Francisco in the National League West after recording three straight wins over the crosstown rival Angels, while Milwaukee stands one game ahead of St. Louis in the NL Central after taking two of three from the Giants. Ryan Braun has one hit in his last 16 at-bats for the Brewers, who will face aces Zack Greinke and Clayton Kershaw on Saturday and Sunday.
