Pineda is the third quality young arm to get traded this winter, following the trades that shipped Gio Gonzalez to Washington and Mat Latos to Cincinnati. Given that both pitchers come with one fewer year of team control and lack Pineda’s dominating fastball, a strong case could be made that the Yankees new starter is the most valuable asset of the three guys that were moved. However, compared to the other two packages surrendered, the Yankees didn’t really pay much of a premium to get Pineda, and one could even make an argument that they gave up less value overall than what the Reds surrendered to get Latos.
I think it's absolutely true that the Yankees made out well in this deal, especially compared to the Reds.
Which doesn't mean it's going to be a great deal for the Yankees. Jesus Montero might become a great major-league hitter, and Michael Pineda might blow out his elbow this summer. And the other two players in the trade, both of them solid prospects, could easily swing this thing one way or the other.
Today, though? The Yankees are looking pretty good, and the Mariners have picked up a 22-year-old designated hitter.
