Here's the win probability chart for Game 1 of the NLCS. There were some big shifts in this game, with the biggest being Carlos Ruiz's three run bomb that cut the Dodgers' odds of winning in half (from 50.7% to 25.2%).
Ryan Howard's double later in the inning that put the Phillies up 5-1 cut the Dodgers' odds in half again (from 25.2% to 11.2%). The Dodgers showed resiliency, raising their odds up to 46.5% after a 6th inning Ronnie Belliard single put runners on first and second with one out and the Dodgers down a run, but they were never again favored to win the game.
The Dodgers had some life until Raul Ibanez's three run blast cut their win expectancy from 17.4% to a mere 3.8%. The final blow was when Casey Blake grounded into a double play in the bottom of the 9th, cutting the Dodgers odds from 19.1% to 1.6%.
The most valuable player (using win probability) was Carlos Ruiz, who had .275 win probability added. He was closely followed by Chan Ho's .240 WPA, and the two most valuable Dodgers were James Loney (.193) and Andre Ethier (.176). Five other Phillies had at least .060 WPA but no other Dodgers did.
Ultimately the game could have gone either way. The Dodgers had more baserunners than the Phillies but the Phils happened to hit homeruns in the only innings where more than one of their batters reached base. It was a tough loss but there's no reason to lose hope.
