LOS ANGELES – The Los Angeles Dodgers' first winning streak of any note ended with a thud.The Dodgers lost 8-2 to the Chicago Cubs Friday, snapping their six-game winning streak and trimming their NL West lead to 2 ½ games. More to the point, it raised questions about some lack of depth in their rotation and bullpen. How it happened: Two struggling veterans put the Dodgers in a big hole by the middle innings. Dan Haren was pulled in the middle of an ugly fifth inning and reliever Chris Perez did nothing to slow down the Cubs' onslaught.
