The Mariners have not been good at the plate in a long time. Not since 2007 was the team unequivocally above average in results and even that seemed more like luck than design when the offense was carried by the likes of Raul Ibanez, Jose Guillen and Jose Vidro. After that year has been four straight seasons of abject disaster in run scoring. By wOBA, or wOBA-related measures, StatCorner (and remember, these are park adjusted) ranks the Mariners 28th, 30th, 30th and 30th since 2007. FanGraphs (by wRC+) is slightly more lenient at 22nd, 25th, 30th and 30th. Either way, the introduction is demonstrated; this has been a team lacking offensive spark for years.
The last pair of seasons has not seen the Mariners been just abysmal and finish dead bottom in the offensive ranks. They have been almost monumental failures. Going by runs against average, the 2010 Mariners were last in the league by a whopping 59 runs, behind the Astros. This past season was not meaningfully better, as the 29th ranked Twins were still 58 runs better. The Mariners weren't just last, they were lapped.
We're familiar with how it came to be. And if you're not, don't worry because it will continue to be covered over the coming months. For now though, before any offseason moves have been made, I ask you to cast forward to one year from now and ponder where the Mariners will have finished 2012 ranking in wOBA. Is it more of the same? Do the Mariners get a small bounce as it appears that they have some decent talents in Mike Carp, Justin Smoak and Dustin Ackley? Does Jack Zduriencik finally snap and go hog wild on bats this winter and the team placates the cries of so many sports radio callers?
