After watching Corey Seager's big-league debut Thursday night, more than a few Los Angeles Dodgers fans had to be wondering, "Why'd they wait this long?" Seager, 21, made a good first impression in his L.A. uniform even though his squad suffered another disappointing loss in which its bullpen took a beating. The Dodgers fell to the San Diego Padres 10-7 , as the Padres scored a total of six runs in the sixth, seventh and eighth innings. [ Bryce Harper's odd night: 0-for-0, four runs scored and an RBI. Huh? Read all about it. ] Before all that, though, Seager looked golden in his debut. It was with sixth-inning single that brought in two runs and gave the Dodgers their first lead of the game, 5-4. That was actually Seager's second hit, the first of his career coming an inning earlier. He doubled and came around to score. Game No. 1 in the books for Corey Seager.
