CHICAGO >> The red, white and blue flags extending from Wrigley Field’s top deck whipped fiercely in a westerly wind as lightning flashed in the distance Tuesday afternoon. A light rain pelted Chicago’s North Side. The bleak, gray sky foretold gloom and so did the Dodgers’ injury report — first Alex Wood flew to Los Angeles to get an MRI on his left elbow, then Yasiel Puig was scratched from the starting lineup with a sore left hamstring.A funny thing happened on the way to the Apocalypse.Scott Kazmir pitched better than he had in his last 10 starts, dating to his 2016 debut. The left-hander gave up one hit, one walk and hit one batter in six innings against the Chicago Cubs. Nobody scored, the bullpen preserved a slim lead and the Dodgers won 5-0.“He’s our No. 2 (starter),” Dodgers manager Dave Roberts said, “and he’s had a lot of success at this level. So to now be healthy and to feel good, he’s seeing the results. He gave us a big lift tonight.” Newsroom GuidelinesNews TipsContact UsReport an Error “I think the most important part of the game was getting those walks late in the seventh, driving (Arrieta’s) pitch count up,” Kazmir said.The Cubs hadn’t lost a regular-season game started by Arrieta since July 25 of last year, a streak of 23 starts. The Dodgers ended the streak one day after they put only two runners on base against five Cubs pitchers, losing 2-0.“We know we’re going to grind,” Gonzalez said. “We’ve got a lot of professional hitters that can get the job done. For us it’s just about grinding out every at-bat like we always do, no matter who’s on the mound, and being able to take a team approach. Our plan was to try and get him out early and get to the bullpen. It wasn’t that early, but when we did get to the bullpen we took advantage.”Seager’s three-run home run off Trevor Cahill in the ninth inning provided the final score. The rookie shortstop has nine home runs this year, which leads the Dodgers.But the star of the game was Kazmir. The embattled veteran, who signed a three-year, $48 million contract over the winter, began the day with a 4.84 ERA. He hadn’t pitched without giving up a run since April 5 in San Diego. In nine starts in between, Kazmir went 3-3 with a 5.40 ERA and given up 12 home runs.Kazmir also had been dealing with an injury to his left hand in the area of his thumb. It was enough of a concern that the Dodgers have prohibited the pitcher from swinging a bat most of the season, but he’s been swinging more of late. A member of the Dodgers’ training staff checked on Kazmir at one point during Tuesday’s game, but the pitcher said he was dealing with a callous on his hand; not the thumb injury.With better health comes better results. In his last two starts, Kazmir has given up one run and struck out 19 batters in 12 innings.This one came against baseball’s best team and maybe its best pitcher.“Going into it you know you can’t make too many mistakes,” Kazmir said. “It was just a big win for us.” It’s more than a side note that Kazmir outdueled the reigning National League Cy Young Award winner, Jake Arrieta. The weather abated in time for Arrieta to throw his first pitch 27 minutes after the scheduled start time.The Cubs’ right-hander was dominant in seven shutout innings. He held the Dodgers to two hits and four walks; one of the hits was a swinging-bunt single by Yasmani Grandal. But Arrieta opened the door a crack by loading the bases in the seventh inning on three walks, then slammed the door shut by striking out pinch hitter Justin Turner on three pitches, the last a 94 mph sinker at the knees. That was Arrieta’s 107th and final pitch of the game.Just when it appeared the Dodgers had wasted their only bullet, the Cubs bullpen took over and melted down.Clayton Richard gave up three consecutive singles to begin the eighth inning. The last of them, by Adrian Gonzalez, scored Chase Utley with the game’s first run. Later in the eighth, Corey Seager scored on a sacrifice fly by Howie Kendrick.
