Urena got the start in Monday's Grapefruit League game against the Twins, allowing two runs in one inning of work on a walk and a two-run home run by Byung Ho Park.
He had trouble keeping the ball in the yard last year, so this wasn't the most encouraging start to Urena's spring. The 25-year-old is out of minor league options and almost assured of a spot on the Marlins 25-man roster for Opening Day, but barring a dramatic improvement in his numbers, he'll likely fill a long relief or mop-up role this season that carries very little fantasy value.
