In the bottom of the first inning, a grand slam and a solo home run gave the Diamondbacks five runs and a lead. Terrific! Surely they could count on Joe Saunders to protect it for a while before giving way to the bullpen, right?
Well. People like me might make a little too much fun of Joe Saunders - he does own a career 103 ERA+, after all - but he doesn't throw a lot of strikes and he doesn't miss a lot of bats, and the end result is that he just plum isn't good. He's good relative to you and me, but he's not good relative to his peers. Relative to his peers, he's just a mediocre starting pitcher trying to find his way in the world.
And mediocre starting pitchers can't be expected to have a ton of success against a lineup like Milwaukee's. Saunders allowed one run in the first. He allowed one run in the second. And he allowed one run in the third. He allowed it quickly, too, when Corey Hart led off with a single, and then flew around third base to score on a subsequent double by Jerry Hairston Jr.
Saunders then walked Ryan Braun, but found a way out of the jam to keep the score 5-3. Still, watching, one gets the sense that there are going to be a lot more runs, and I don't know who's going to score the majority of them.
