PITTSBURGH—The Pittsburgh Pirates have stuck with Charlie Morton in their starting rotation despite his awful start.On Wednesday night, Morton showed why.Morton was effective for the first time this season, allowing two runs in six-plus innings, and the Pirates beat the Cubs for the second straight night, 4-2.Morton (1-5), who entered the game as the worst starter in the majors in terms of ERA (12.57) and was tied for worst with five losses, did not allow a hit in five of his six innings and did not walk a batter to win for the first time since shutting out the Cubs Sept. 30.Ted Lilly didn’t walk a batter and there were no free passes in the game.Ryan Church homered for the second consecutive game, Garrett Jones had two hits and two RBI, and Octavio Dotel earned his fifth save in seven opportunities for Pittsburgh, which improved to 9-1 in games decided by two runs or fewer.Slumping Aramis Ramirez was moved down to the No. 6 spot in the order but had a hit and an RBI.Morton retired the first eight Cubs before hitting Lilly with a pitch with two outs in the third. He allowed four hits in a two-run fourth but retired the next seven before being lifted when Ramirez singled to lead off the seventh.In his previous five starts, Morton hadn’t allowed fewer than six runs and had completed at least four innings only once.Three of the first four Pittsburgh batters of the game had hits against Lilly (1-2), but the Pirates pushed across only one run, Bobby Crosby scoring on Jones’ single.The Pirates began the third with three straight doubles, taking a 3-0 lead when Andrew McCutchen and Jones drove in Andy LaRoche and McCutchen.Church’s homer was on an 0-1 pitch to right with one out in the sixth. He has reached during all eight games he has appeared in at PNC Park this season — despite the fact he’s had a case of the stomach flu the past two days when he homered.Lilly was charged with four runs and nine hits with two strikeouts in six innings. He was making his third start since being activated April after offseason shoulder surgery.The Cubs, 3-2 losers here Tuesday after a three-game winning streak at home, got all their runs in the fourth on Ramirez’s sacrifice fly and Mike Fontenot’s RBI single.
