Players leaving teams for new ones is a regular occurrence in MLB—it's part of the job description. Sometimes players leaving is for the better, and sometimes it's unexpected and to the dismay of loyal fans. Much of it has to do with team needs, but contracts and money are just as big of factors.
Before I go into players who likely won't return to the Seattle Mariners next season, let's look at the possibility of a new skipper righting the ship.
Eric Wedge is in the final year of his contract and is on pace for a third straight losing season. The 75 wins last year were an improvement over 67 in 2011, but the upgraded roster this season was supposed to bring even more wins to Seattle.
Granted, there have been major injuries to key players (Michael Morse, Franklin Gutierrez), and the lack of a starting catcher hasn't helped either. We've seen a couple stretches of great baseball and even an eight-game winning streak. But at the end of the day, the Mariners are a mediocre team with more power than in years past, but they have downgraded pitching.
While the roster changes are out of Wedge's control, the added bats combined with smaller Safeco Field dimensions were supposed to boost an offense that's been one of the league's worst for half a decade. The home runs totals have gone up, but the M's still aren't scoring many runs. And when they do, the pitching falters.
Wedge's lack of improvement record-wise coupled with recent health issues may open the door for a new manager to take over the Mariners next season.
Now, here are some Seattle players who likely won't return next season.
