The shortstop, Boston's first selection in the 2012 First-Year Player Draft (No. 24 overall), represented Class A Lowell at Fenway Park on Saturday afternoon. He went 1-for-4 in his Futures at Fenway Debut.
Four years ago, Will Middlebrooks had a walk-off hit for the Spinners in the annual game that showcases some of the organization's top prospects. Middlebrooks broke in with the Red Sox in May and hit .288 with 15 homers and 54 RBIs before a fractured right wrist ended his rookie campaign. Daniel Nava, Mauro Gomez and Ryan Kalish have also come up through the club's farm system and have given the Sox a boost this season.
"You want that to be you in a couple of years," Marrero said. "We see that those guys have worked hard and that makes us work even harder because those guys put their work in and it's paying off for them now. They're up their doing great in the big leagues showing everybody that they belong."
The Red Sox have promoted 18 players from Triple-A Pawtucket this season.
"That's a tribute to those guys and how hard they work and being comfortable when they come up to just go out and play and do what they did to get them there," PawSox manager Arnie Beyeler said.
While Marrero still has plenty of seasoning to go through in the Minors, he could be with the Sox in the near future. He leads the New York-Penn League with 21 stolen bases. The Arizona State product is hitting .260 with two homers, 11 doubles, 15 RBIs and 32 runs in his first 50 games as a professional.
"The coaches are great, I'm learning so much here, just little thing about the game that I never knew," Marrero said. "I try to get better every day, try to work on things every day and we have great coaches who make us work every day."
