Mark Trumbo
Mark Trumbo has played for the D-backs, Angels, Mariners, and Orioles in his career and has been much the same hitter for each team. A guy who can hit the ball a long way out of the ballpark. While that may sound appealing, for most of his career he has struggled to make enough contact to make his power count. While he is still very strikeout prone as an Oriole he is hitting with enough power at a high enough clip to make a difference.
He has already hit over 40 homers this season while maintaining an average above .250 (Something he has struggled to do at times in his career). He has set a new career high for hitting balls out of the park and has more than paid off for the discounted price the Orioles acquired him for.
Considering his career, it is a stretch to include Trumbo on this list but based on this season alone he has earned a spot. The season Trumbo is having is one that Orioles fans better enjoy while it lasts because it is doubtful that Trumbo puts up another season quite like this one.
