He was rated as the No. 19 prospect in the Brewers' system by MLB.com before the season started, and though he took a step back when he began his pro career, the team's front office is happy with what it's seen this year.
"Lopez has made a lot of progress," Brewers assistant GM Gord Ash said. "He's got a good fastball, very good command. He's a very good competitor, and the last year he's really come on."
In terms of fastball velocity, the closest comparable on the Brewers' staff may be Yovani Gallardo, who pitched a scoreless inning in the 2006 Futures Game.
Other current Brewers who have participated in the event include Ryan Braun, Matt Garza, Scooter Gennett, Tom Gorzelanny, Lyle Overbay, Francisco Rodriguez, Jean Segura, Tyler Thornburg and Rickie Weeks.
"It's certainly a privilege to play in it," Ash said. "It's a good idea that they brought it to fruition  years ago. A lot of scouts attend. That's where we saw Segura and [Ariel] Pena for instance [before the Brewers acquired those players from the Angels in the Zack Greinke trade in 2012]. It's a good reward, and it probably heightens a player's profile."
One player who can attest to that is Brewers third baseman Aramis Ramirez, who played in the inaugural Futures Game in Boston in 1999. Ramirez said he went 0-for-1 with a walk but had a great experience playing at Fenway Park.
"Its fun. You're out there with all the best prospects in the game," Ramirez said. "It's fun any time you have the opportunity to do that."
