Urena split time between Triple-A and the majors in 2016, as he was sent down and recalled by the Marlins on multiple occasions. While Urena made 12 starts and 28 overall appearances for Miami, his performance in the big leagues this season was relatively unspectacular. The 25-year-old earned a 6.13 ERA and 4.72 FIP in 83.2 innings of work. His struggles resulted in part from his inability consistently generate strikeouts, resulting in a disappointing 6.2 K/9 rate. The Miami right-hander also had fairly extreme splits, as righties slashed .236/.320/.405 off him while lefties were able to slash .298/.359/.506 in 2016. Urena is still young at 25 years old, so there is certainly still a chance that he will improve upon his first couple of stints in the big leagues. Urena likely won't be in the Marlins' rotation to start the season, but he has a good chance to be a spot-starter and the first guy asked to fill in if one of Miami's starters goes down with an injury.

As he had the previous three seasons, Urena moved up in the Marlins organization. Due to injuries, however, he made more appearances in the major leagues than was originally expected for him. The right-hander had his fair share of struggles in his first showing in the majors, going 1-5 with a 5.25 ERA, 1.59 ERA, and 1.12 K/BB. He did see success while pitching with Triple-A New Orleans, though, posting a career best 2.66 ERA while going 6-1 in 11 starts. The Marlins have plenty of young pitchers, but if the 24-year-old can carry that success he saw in the minors to the majors, he could find a spot as a long reliever with the Marlins or even push for a rotation spot with a strong spring.

Another year, another step up the Marlins’ ladder for Urena, who collected 162 innings with a  3.33 ERA, 1.14 WHIP and 13 wins for Double-A Jacksonville during his fourth professional season. Urena continues to show exemplary control for a 23-year-old (1.61 BB/9 in 2014) while striking out a career-best 121 batters last season. Urena tends to work to contact with his mid-90s heater but is effective at keeping in the ball in the yard. Still, he’s unlikely to find much growth in his strikeout potential until a more effective secondary offering is established. Urena will likely take his superb command to Triple-A in 2015, but will be hard pressed to find opportunity in the majors this season with the Marlins possessing talented rotation options both in the big leagues and in the high minors.

Urena racked up a 3.73 ERA in 27 games (26 starts) at High-A Jupiter during his age-21 as he continued his climb up the ranks in the Marlins' pitching-rich farm system. The right-hander has modest strikeout ability -- registering 107 punchouts in 149.2 inning pitched last season -- but has already shown plus control, walking just 1.8 BB/9 over his past two seasons. Urena touches the mid-90s with the heater and also boasts an improving slider that will need further work to become a valuable offering. He is likely to start 2014 at Double-A and could have a shot to make his big league debut when rosters expand in September.
