We’re in a bit of a lull today with the offseason leagues winding down and the winter meetings set to start tomorrow, but there have been a few interesting transactions involving prospects. Next week’s rundown should be a tad meatier once the teams depart Vegas and have (hopefully) made some trades/moves. One of the teams that is kind of fascinating to watch right now is the Miami Marlins. I would expect them to move J.T. Realmuto this offseason (maybe this week), and I’d also expect the return to be centered around prospects. The team is obviously in rebuild mode, and since they’re not likely to be ready to compete in 2020, it makes no sense for them to hold the backstop. So let’s start with Miami, who signed a bunch of players to minor league contracts last Monday.

Alright 12 readers still with us in late October, get your firecrackers, noisemakers, and elated cheers ready. For the return of Minor League Preview season is upon us. I know, I know, exciting times across Razz Nation. With that said let’s curb your enthusiasm a little, we’re starting with the Arizona Diamondbacks. Lower case yay…. What can be said about the Diamondbacks system that hasn’t already been said about Detroit? It’s been decimated, depleted, and burned to the ground. Mostly by Dave Stewart, but I’m sure Tony LaRussa had a hand in that too. Top prospects like Dansby Swanson, Isan Diaz, and Aaron Blair were shipped off, and to make matters worse they lost their first round draft pick after signing Zack Greinke. So we’re looking at a handful of second division regular types, some back of the rotation arms, and some long term toolsy players. Not exactly the bang you were looking for, but at least we have the Braves to look forward to. Heck they have at least 70 former Diamondback prospects. Holla Touki!!!

The Gist
The Mariners just missed the playoffs in 2014 and graduated several quality prospects along the way. Felix Hernandez and Hisashi Iwakuma will be joined by Taijuan Walker, James Paxton, and Roenis Elias. Elias had a solid rookie season and will look to keep that going, while Walker aims to show why he was the organization’s top pitching prospect. The Mariners took one of the most exciting players in this year’s draft when they selected Alex Jackson sixth overall. The farm is stocked with enough pieces to make moves at the trade deadline if they go into buy mode either in the offseason or in July. On a side note, Seattle moved out of the launching pad of High Desert and now calls Bakersfield their High-A home after this year’s affiliation shuffle.

In his first plate appearance of spring training, a big league camp AB versus David Phelps, Gregory Polanco turned on a breaking pitch, sending it over the right field wall. Such things happen to 22-year-olds during spring training, and most of the time, they’re anomalies. In Polanco’s case, however, that moment, in retrospect, seems profound — a statement as to his readiness to produce at the highest level from the instant he stepped on a diamond this spring. Reassigned to Triple-A to begin the season, Polanco’s statements have only grown louder. Through 92 PA, he’s hitting .417/.467/.679 with 4 HR and 4 SB, making him the best mixed league stash in the minors. The Bucs have been fortunate thus far to squeeze some production out of their Travis Snyder/Jose Tabata platoon, but the upside with Polanco is unquestionably higher and it’s only a matter of time before Pittsburgh slots him into their lineup as the everyday RF. His incredible start at Indianapolis should allow him to segue into big league ball with a shizzload of confidence.

The Run Down
When considering the Mariners farm for fantasy purposes, it’s impossible to ignore the Safeco effect.  Every pitcher on this list should carry inflated fantasy value thanks to the ballpark at which they’ll be spending most of their time.  On the flip side of that statement, however, the M’s offensive prospects aren’t necessarily as exciting as they could be.  We apply the same principle when evaluating the Padres or Giants farm systems — never shy away from a pitching prospect pushing through the Seattle org.
