MILWAUKEE -- If you’ve been following the Brewers, surely you know the name Charlie Greene. The 52-year-old coach has worked behind the scenes with the club’s catchers for 19 seasons and counting. 

Greene’s current title is assistant director of player development, but he’s best known as the Brewers’ roving catching coordinator. He has been part of the defensive development of backstops from Jonathan Lucroy to Manny Piña to Omar Narváez to current primary catcher, William Contreras, who has transformed into one of the sport’s premier receivers and pitch-framers seemingly overnight. 

Greene was at American Family Field for a few days this week, before heading to High-A Wisconsin, his last stop on an early season tour of Milwaukee’s full-season Minor League affiliates. He answered a few questions about his position and more.

Fans often hear the term “roving coordinator,” but might not know what that role entails. When you visit an affiliate, what exactly do you do?

Greene: "We help support the staff. I tell the manager, 'Anything you need help with, I’m here.' And the catching department, I’m overseeing that, so I’m always into that part of it. We get to fill in the blanks. We have [roving coordinators for] hitting, pitching, outfield, baserunning, catching, and we’re always following the games, so we know what’s going on night to night, but we haven’t seen the games live. So, the manager runs the show, and we help support. That’s the best way to describe it."

“The best part is being in the dugout. Sometimes our guys will watch from the stands because you get a different, bird’s-eye view, but I like being in here with the catchers and pitchers because I can hear them talk between innings, and I can communicate if I need to say something to the catchers during the game. There’s nothing like getting a feel for the guys and seeing it live."

What about when you’re not there live?

Greene: "We have videos of every pitch of every game the whole year, from extended spring training all the way through Triple-A. But there’s something about live action. This is my 19th year doing this, and we have more [rovers] and more cameras. When I started, I think maybe Triple-A had TV, but that was it. I brought my own camera, for crying out loud. 

“Now there’s just so much more data and knowledge. We have our hands on way more than we used to. Back then, you got your information from box scores and game reports and your eyes. We had to make more educated guesses. The only numbers we talked about were ERA, batting average, walks and strikeouts and errors. But errors don’t tell you any part of the picture of defense, no chance. It’s changed for the better.”

How would you assess the state of catching in the system?

Greene: "Pretty good. You have the veteran guys [Brent Diaz and Brian Navareto], plus Payton Henry and Alex Jackson on the seven-day injured list] at Triple-A Nashville, Jeferson Quero and Wes Clarke and the guys in Double-A Biloxi, then Darrien Miller and Alex Hall up here in Wisconsin and Matthew Wood down in [Single-A] Carolina. 

"Matthew Wood [MLB Pipeline’s No. 27 Brewers prospect] is probably off to the best start of the catchers right now. He’s off to a great start. He’s just a steady performer, is the best way to describe it. He frames well, he’s got a quick release, he works well with pitchers, he hits, he has a good eye at the plate, he’s got some juice. He’s just a steady performer. We’ve had a few of those -- Jonathan Lucroy was one. 'Good in a lot of areas’ is good in this game. "

What about Quero, MLB Pipeline's No. 5 Brewers prospect

Greene: "He’s good, man. At the start of the year, I think he was the fifth-youngest player in the Southern League. So, he’s like a college sophomore jumping into Double-A, and he’s playing great defensively. He’s nursing a bad thumb a little bit, and he’s probably going to have to nurse that for a while. That’s the life of a catcher. But he hit some home runs this past week, and he’s putting on a show throwing. He’s throwing the ball really well."

Is Quero's defense ahead of his catching?

Greene: "I don’t know about that. He’s an all-around guy. He has a chance to be special. An elite defender with some power who can hit, that’s what you look for behind the plate. But his best part is how he’s wired. I think his makeup is his best tool. He’s wired to serve and to lead. And you know, he’s always going to be young, catching older guys. At least for the next few years. He’s going to be the youngest kid in the room. But he’s got some moxy, some street smarts, some toughness. He’s wired right."
