Tuiasosopo has fallen off of every radar screen after failing to hit through aggressive promotions in the past few years, but after a terrible first 2 months he's been tearing it up in Triple-A.

Since June, he's hitting .302/.393/.526 - good for a .920 OPS in 264 ABs, including an august where he hit .341/.415/.659 with 7 home runs  This despote playing in the most extreme pitchers' park in the PCL.  He's still only 22, and he can play a legit third base. Mariners prospects tend to be overlooked because to a man they're always playing a level or two above where most teams would slot them, but he's looking like a legitimate prospect to me.
