In a trade that many felt was inevitable, the Diamondbacks have traded outfielder Mark Trumbo to the Mariners for four players, including catcher Welington Castillo. Here is the deal, as reported by Ken Rosenthal for Fox Sports:

All told, the Diamondbacks give up Trumbo and pitcher Vidal Nuno for Welington Castillo, pitcher Dominic Leone, infielder Jack Reinheimer and outfielder Gabby Guerrero. So, the Diamondbacks really didn't get much for Trumbo, although they did get a starting catcher in Castillo, so he has some fantasy value now that he will play his home games in Arizona.

Moving from Chase Field in Arizona to Safeco Park in Seattle hurts Trumbo's fantasy value, as Safeco is one of the toughest parks to hit a homer in, depressing home runs by almost 20% this season. Trumbo will probably play some outfield and DH for the Mariners and attempt to boost a Mariners lineup that is struggling to score runs this season.

The trade of Trumbo allows the Diamondbacks to move rookie Yasmany Tomas to the outfield, opening up third base for Jake Lamb, who is returning from the disabled list in the coming weeks. Lamb will start a rehab assignment tonight, and will probably need at least a week, maybe two, before his return to the Diamondbacks lineup.While Lamb is rehabbing in AAA, I assume Aaron Hill will see some time at third base.

The Diamondbacks get two prospects in the deal, including Vladimir Guerrero's nephew, Gabriel Guerrero. Guerrero made our Mariners top 10 fantasy prospect list back in the offseason, and here is what Brian Creagh wrote about him:

The comparisons to his Uncle Vlad are scary. Gabriel Guerrero flashes the raw tools that make you think he's going to be something special and he shows the same free-swinging approach that made Vladimir so unique. The risk comes with projecting anyone to be able to become another Vladimir Guerrero. Toolsy and capable of putting up big fantasy numbers, Gabriel Guerrero has the widest range of outcomes of anyone on this list. He spent all of 2014 at Hi-A, High Desert, which is an offensive launching pad. His numbers are still impressive with a triple slash of .307/.347/.467, 18 HRs and 18 SBs.

Guerrero has an average hit tool, solid-average power, and average speed, but it's his aggressive approach to hitting that makes you wonder how it will all come together. In 131 games last year, Guerrero struck out 131 times and walked just 34. His hand-eye coordination is out of this world and covers a lot of the weaknesses his approach creates, but there's always concern that as the pitching becomes more advanced, the contact ability will not sustain. Scouts are split on Guerrero - some love him and see a spitting image of his uncle, others are concerned the bat won't play at the highest levels until he learns to navigate the strike zone.

Guerrero will play the next season at 21 years old and will face the ever-crucial AA test. Another .300+ AVG season should catapult him into Top 50 prospect status, but in the meantime he's a fringe Top 100 player. The power leaves something to be desired and the hit tool comes with questions on his approach, so even if it all clicks, the upside isn't that of Jackson or Peterson.

This season, Guerrero is hitting just .215-.262-.305 with 2 home runs 22 runs scored, 15 RBI and 3 stolen bases in 191 plate appearances in AA. As Brian wrote in the above profile, Guerrero is striking out a lot - 25% - and not walking much - 5%, but maybe a change of scenery will change things for him at the plate.

Reinheimer is hitting .277-.323-.351 with a home run, 25 runs scored, 16 RBI and 12 stolen bases in 219 plate appearances thus far in AA. He doesn't hit for power, but stole 39 bases last season between Low A and High A.
