Seager and Mariners agree to huge extension

Seager represents perhaps the best player in the past decade-plus in Seattle's rarest of rare categories: a home-grown hitter.

Coming off of his first All-Star season and first Gold Glove, Kyle Seager appears to be on the verge of another huge accomplishment before 2014 is out. Yahoo! Sports' Jeff Passan broke a story this morning (not yet confirmed by the Mariners, but numerous reports of confirmation have come in to those in the know) that Seager and Seattle are in agreement on a 7-year, $100 million contract extension with an option for an eighth year that will buy out his three arbitration seasons and keep Kyle in Seattle at least through the end of 2021.

Once this deal is signed, Seager will become one of the youngest players to agree to a $100 million-plus contract before arbitration. But while that does represent a large and uncommon financial commitment by the M's and puts them in a spot of having nearly half a billion dollars allocated to the future contracts of just three players, Seager appears to be able to live up to the huge value of the deal.

Since 2010, there have been six total seasons by third baseman playing in their age-26 season or younger to get 5.5 or more fWAR -- Kyle's 2014 is one of those years. Only 21 players have accumulated more fWAR since the start of the 2012 season than Seager, and only five of those are the same age or younger than the now 27-year-old North Carolina product. Those five are Mike Trout, Andrew McCutchen, Jason Heyward, Giancarlo Stanton and Paul Goldschmidt; a group widely recognized as some of the best young players in baseball.

Seager now teams with Robinson Cano and Felix Hernandez on long-term deals for the M's, further solidifying the core of a club that appears to be on the brink of building an annual contender out of the ashes of the last 10 years.

Seattle's third round pick in the 2009 draft, Seager has produced much more than what many predicted of him when he was rocketing through the minor leagues for the M's, particularly in the power department. He's been out-homered by just 11 left-handed hitters since the start of 2012 and hit a career-high 25 in 2014 -- the same number as Miguel Cabrera and good for a tie for 14th most in the AL and 21st most in baseball. If Seager simply maintains his average production from the last three seasons over the life of the deal then he would produce about 30 fWAR in the next seven seasons. One "Win" was said to be worth $5m and $7m prior to the 2014 season, so any way you slice it it looks like the M's made out well here.

With Seager now taken care of, look for the Mariners to begin to make serious waves in the free agent and/or trade market for more offense in the coming weeks.
