Dodgers able to overcome Cubs' power surge

GLENDALE, Ariz. -- Omar Luna's RBI single in the bottom of the eighth helped the Dodgers overcome three home runs by the Cubs in a 7-6 Cactus League win on Monday at Camelback Ranch.

Nate Schierholtz, Darnell McDonald and Welington Castillo all homered for Chicago in the loss.

Matt Wallach's RBI single tied the game at 6, as the Dodgers overcame an early 6-2 deficit.

Chad Billingsley, in his first start for the Dodgers after missing the last six weeks of 2012 with a partially torn elbow ligament, was roughed up in the first inning for two runs on extra-base hits by the first three Cubs batters -- doubles by Luis Valbuena and Darwin Barney, and Schierholtz's homer.

The Dodgers answered with a two-run single by Nick Punto in a bottom of the first that started with a 16-pitch strikeout of Dee Gordon and a pair of walks by Cubs starter Carlos Villanueva, who was replaced after Punto's hit by Blake Parker.

Chicago reclaimed the lead in the third inning on back-to-back homers by McDonald and Castillo -- McDonald's a three-run blast -- off Chris Capuano, who picked up for Billingsley.

The Dodgers scored three runs in the fifth inning without a hit off Robert Whitenack, who loaded the bases on a pair of walks and a hit batsman, the first two runs scoring on a balk and groundout. The Dodgers scored a third run later in the inning on another balk, this one by Michael Bowden.

Up next for the Dodgers: Josh Beckett will make his first start of Spring Training when the Dodgers host the Giants on Tuesday at 12:05 p.m. PT. Beckett is reinventing himself as a pitcher after an impressive career as a hard-thrower and has spent considerable time in the past week working with Hall of Famer Sandy Koufax. Owed $31.5 million over the next two seasons, Beckett is virtually assured a spot in the starting rotation -- even though there won't be room for three of the eight current candidates.
