The kid is growing up. Growing up, not grown up. Not quite yet. But it’s clear that infielder Brendan Rodgers, the Rockies’ top prospect and the third overall pick in the 2015 draft, is miles removed from the wide-eyed, $5.5 million bonus baby who started his professional career at age 18, fresh out of Lake Mary (Fla.) High School. “There isn’t any question that Brendan’s matured,” said Zach Wilson, the Rockies’ director of player development. “He has certainly been very intentional about doing what it takes to be a professional. He’s done all the work. It also means he’s learned to be all about the team, realizing it’s about helping out everybody around him.” Rodgers’ objective is to make his big-league debut this season, and he’s not shy about saying so. “Yes, absolutely, that’s my goal,” he said Tuesday after wrapping up an offseason workout at the Rockies’ complex at Salt River Fields. “My first goal is to say healthy, the next goal is to get to (the majors) this year. I definitely think it’s achievable and that’s what I’m going to keep my eye on.” Wilson likes the sound of that. “We’ll see what happens, but it certainly doesn’t hurt to have those aspirations and those goals this year,” Wilson said. “But I will also say this: we’ll make sure he is ready for the next step before he takes it.”
