Tyler Mahle gave up one run over five innings Thursday and Scooter Gennett drove in three runs with three hits as the visiting Cincinnati Reds rallied for a 4-1 victory over the Los Angeles Dodgers. Mahle, a Southern California native who was making his first start at Dodger Stadium, had to scramble early, leaving the bases loaded in the first two innings. Raisel Iglesias recorded the final four outs for his fifth save.
