HOUSTON — Cody Bellinger pulled into second base with his first World Series hit and said: "It's a miracle!"With the Dodgers three innings from falling into a deep deficit, the rookie slugger sparked a late comeback that stopped the Astros' surge.Hitless in 13 at-bats, Bellinger doubled and scored the tying run in the seventh inning then doubled home the go-ahead run off struggling closer Ken Giles in a five-run ninth that lifted Los Angeles to a 6-2 win Saturday night and tied the Series at two games apiece."Relief, for sure," Bellinger said. "I think everyone knows I was struggling."George Springer put the Astros ahead with a two-out homer in the sixth, the first hit off Los Angeles starter Alex Wood. The crowd at Minute Maid Park, where the Astros had been 7-0 this postseason, was revved up in anticipation of the Astros having a chance to win the first title in their 56-season history tonight.Instead, the Series will go back to Los Angeles no matter what. Clayton Kershaw starts Game 5 for the Dodgers tonight and Dallas Keuchel for the Astros in a rematch of the opener, when Kershaw pitched Los Angeles to a 3-1 win."I like where we are at," Dodgers manager Dave Roberts said.Bellinger, a 22-year-old bopper who set a National League rookie record with 39 home runs this season, struck out four times in Game 3 and once more in the fifth inning — his eighth whiff of the Series.Roberts expressed faith Friday night in Bellinger and again Saturday afternoon."He's got that calmness about him," Roberts said. "And when things speed up, he has a way of sort of resetting and not letting it spiral."Bellinger doubled over leftfielder Marwin Gonzalez, chasing starter Charlie Morton, and came home on former Ray Logan Forsythe's two-out single off Will Harris.Giles entered to start the ninth and got into immediate trouble, allowing a leadoff single to Corey Seager walking Justin Turner. Bellinger took a low slider then lined a fastball at the letters to left-center. He raised a hand rounding first and clapped his hands half a dozen times in excitement after sliding into second.Joe Musgrove relieved and allowed Austin Barnes' sacrifice fly and Joc Pederson's three-run homer, his second home run of the Series.Wood, Brandon Morrow, Tony Watson and Kenley Jansen combined on a two-hitter. Jansen allowed Alex Bregman's two-out homer in the ninth.
