Mark Trumbo traded to Diamondbacks; Tyler Skaggs, Adam Eaton leave Arizona

Here are the details of the trade:

• Arizona Diamondbacks - Receive Mark Trumbo from the Angels, and two players to be named later, one each from the White Sox and Angels. Send Tyler Skaggs to the Angels, Adam Eaton to the White Sox.
• Anaheim Angels - Receive Tyler Skaggs from the Diamondbacks, Hector Santiago from the White Sox. Send Mark Trumbo and a player to be named later to the Diamondbacks,
• Chicago White Sox - Receive Adam Eaton from the Diamondbacks. Send Hector Santiago to the Angels, a plaer to be named later to the Diamondbacks.

Mark Trumbo is a 27-year-old who has played mostly at first-base, with limited left-field experience. He did have 34 home-runs last season, but hit .234, which helped pin his OPS+ down to 109, and he was worth only 2.2 bWAR. He will be in his first year of arbitration, being under Diamondbacks' control through the end of 2016, and it's estimated he'll earn about $4.7 million next season.

Tyler Skaggs is re-united with Jerry DiPoto, the Angels' GM who occupied the same role with Arizona, when Skaggs arrived with the Diamondbacks in August 2010. Skaggs has played in 13 games for us, putting up a 5.43 ERA. It should be noted, he is still very young - Tyler only turned 22 in July - though there have been question-marks about an apparent drop in his velocity, which has reduced his value.

Adam Eaton has gone from a potential Rookie of the Year candidate for the Diamondbacks, to "not wanted on voyage" in less than ten months. He missed the start of this season due to an elbow injury, and struggled somewhat on his return, putting up a .674 OPS, and proving significantly less valuable overall than our other young outfielder, A.J. Pollock. However, there were still strong hopes for Eaton in 2014 and beyond.

The two players to be named later, are likely prospects eligible for the Rule 5 draft which takes place later this week. This would tend to suggest they are not exactly blue-chip names; not that either the White Sox or Angels farm organization were exactly overflowing with those to begin with.
