A 6-foot-6 combo forward, Marrero is the type of player that gives it 100-percent every time he steps on the floor. Whether it's the first play of the game or the last, his energy is unmatched.
This past weekend at the Shootout at the Hall in Champaign (Ill.), Marrero put together a 20-point, 13-rebound effort while helping his Gary (Ind.) Bowman Academy squad dismantle Peoria (Ill.) Manual by 19 points.
Marrero was on top of his game on both ends. Offensively he scored at will around the basket, but he also defended, rebounded and pushed the break at every opportunity.
"I get offensive rebounds and I can bring the ball down the court," Marrero responded when asked to describe his game. "I have a good engine and I can dish out to open people."
For his high school team, Marrero is forced to spend majority of his in the post. But during the AAU season he spends time on the wing trying to fine-tune his ball skills because he believes he'll be playing small forward at the next level.
"A little bit," he said when asked if it was frustrating spending so much time inside. "Because I'm used to playing the three, but I'm playing five for this team. But I guess it's good that I can play all five positions."
Marrero, a 2012 prospect, said the transition to the wing spot is something that he's been focusing on for quite some time.
"It's going tremendous," he said. "I've been working on my jump shot and my penetrating. I'm working on my ball handling and my jump shot. I'm just trying to get ready for college even though I have a long ways to go."
"It's going well," he said of his recruitment. "I went to a Purdue game when they played Wake Forest. It was very loud. It was good to go to a live basketball game. I went to a Ohio State football game."
Marrero has also been Indiana and Illinois campus a handful of times. Marrero doesn't appear to be in a hurry to make a college decision.
"I just don't focus on it right now," he said. "I'm putting my team first right now. Purdue has been in my favorite five. I've just always kind of liked Purdue. But I'm not concentrating on it right now. When the time comes I'll decide."
Although he stopped short of calling Purdue his favorite school, he did admit that he was among his favorite schools. His recent visit has a lot to do with his affinity for the Matt Painter's program.
"I like the atmosphere," Marrero said. "It was tremendous when I went. I'm going to go back down on the 28th when they play Michigan State. I like big crowds. It was nice."
