Really there isn't much to say. In the battle of "my team won't score any runs when I'm on the mound" pitchers, Volstad sadly was the winner...loser...whatever -- the Marlins lost.
The Fish had trouble trying to hit a soft-tossing lefty -- big shock. The Giants scored both of their runs when Volstad gave up his team leading 12th home run in the fourth. You know, at the start of the season, if you had bet me that Volstad would be leading the team in home runs allowed on June 5, I would've bet the farm (and no, I don't have a farm) on the it ain't going to happen option.
Time to try it again.
