• The M’s Home/Road Scoring Split

    Last night’s latest nine-run road outburst by the Mariners has thrust them into a very unusual position this late in the season.

    As of right now, the Mariners own the distinction of having scored the most road runs of any team in baseball while having scored the fewest at home. Has that ever happened over a complete season? I truly doubt it. It hasn’t happened over the past decade and it’s not even close.

    Now, let’s say this up top: the Mariners have played a few more road games than many teams, so yes, we would expect them to have scored more runs away from home than most clubs. But when you look at the “runs per game” average for the Mariners, it’s actually still third-best in all of baseball on the road. Only the New York Mets at 5.07 runs per game and the Yankees at 5.05 are higher than Seattle’s 4.96.

    So, another blowout or two of the Class AAA level Kansas City Royals pitching we’ve seen the last two nights and the M’s could legitimately be right at the top — regardless of the number of games played.

    At home, the M’s are the very worst in baseball at a 2.86 runs per game average. San Diego is the next closest at 3.02 and the worst American League team in home offense is the Oakland Athletics, who sit way, way up there at 3.68.

    Going back over the past decade, I can’t find any examples of a home/road split where a team is scoring more than two runs per game less at its own ballpark than on the road. That’s just crazy. But the Mariners are somehow pulling it off.

    Usually, when you see such extreme splits, it’s the home numbers that are far out in front of the road stats.

    The biggest case of this was the pre-humidor Colorado Rockies, who now keep their gameday baseballs in a humidor to reduce the effects of altitude on how balls travel. Prior to the humidor being implemented, the Rockies in 2000 averaged 7.81 runs per game at home versus 4.14 on the road.

    In fact, the Rockies routinely had a differential of two or more runs between their altitude-impacted ballpark and everywhere else they played.

    Maybe it’s time to move in the fences at Safeco?
