Matt den Dekker

Picked up at the end of spring training last season when the Mets had a roster crunch and the Nationals needed some outfield depth, den Dekker bounced back and forth between Washington and Triple-A Syracuse and made little impact at either stop before making a late-September surge at the plate after the Nats had been eliminated from the playoff picture. The left-handed hitter is an able hand defensively who can play all three outfield positions, a useful skill in an organization with some aging, injury-prone regulars, and while he posted some big numbers in the desert at Triple-A Las Vegas in years past, his offensive production at sea level has always restricted him to a bench role in the majors. Den Dekker will likely head into 2016 as the Nats' fourth outfielder, and with Jayson Werth still penciled in as the left fielder, it's a role that could provide him with a surprising amount of playing time.
