With their stirring 3-1 win over the Miami Marlins yesterday, the Giants finally snapped a seven-game losing streak. Losing streaks are never fun to watch, but if you thought the Giants played especially terribly over that winless week, you’d be right. The Giants were outscored 63-19, a run differential of -44 runs. If you extended out that run differential over 162 games, you’d have a team that was outscored by 1,018 runs. When I first did that calculation, I had to walk straight into the ocean. But before I got out of Portland, I turned around and went back to my computer.
