Logan Morrison – .229/.300/.385, 92 wRC+, 0.3 WAR

The good thing about LoMo is that nobody really expects much from him. The bad thing about LoMo is that he sucks. The worst thing about LoMo is that many treat him like some kind of a contributor, which he most certainly is not. He plays an offense-only position and hits worse than the league as a whole. Sometimes he gets hot and his wRC+ rises juuuuust above 100, at which point we are for some reason perfectly okay with him. We shouldn’t be, though. We’re just… conditioned. Grade: C

Brad Miller – 294 PA, .247/.322/.413, 109 wRC+, 1.7 WAR

Don’t look now, but Miller’s quietly on pace for a season in the four win range. He’s developed into a solidly above-average player at a critical defensive position. He’s got plenty of pop for a middle infielder and can work his way on base despite subpar contact skills. Oh, and he’s (usually) a treat to watch in the field. The M’s have been scary close to trading him in the past. I hope they now see what we all see. Grade: A-

Kyle Seager – 356 PA, .269/.329/.438, 114 wRC+, 2.5 WAR

The M’s best player this year – Felix Hernandez included – Seager is justifying his $100 million extension. The offense is a little down, but the seemingly unsustainable defensive gains from a year ago are still all the way there. Seager is both solid and spectacular, exactly the type of player the Mariners can’t have. If they only get one, at least it’s this guy. Grade: A
