After waiting a long time for his first home run, rookie Kris Bryant had to wait a little longer to celebrate. Bryant, who was expected to provide the Cubs with a power surge after his early season call-up from Triple-A, hit his first Major League home run on Saturday night in the Cubs’ 12-4 loss, driving a first-pitch slider from Kyle Lohse deep over the wall in left-center for a three-run shot that gave the Cubs a 3-2 lead in the third inning.
