You’re not supposed to be happy at the end of a 2-8 road trip. But then, you’re not supposed to beat Dan Haren and Brandon Webb, on their own turf no less, on back-to-back nights. Because the Dodgers did the latter, they are entitled to do the former. They are right back in this thing, folks, and if they have a good showing against the Snakes at home this coming weekend, it’ll be time to buckle your seatbelts — and maybe even to head down to BevMo to see how much champagne costs. Dodgers go to 67-70 and now trail the Snakes by 2 1/2. But the one thing the boys simply can’t afford is to get tripped up by the Pods. Three-game series starts tomorrow night (5:10 p.m.) at Chavez Ravine. See you there.
