During this week's GM Meetings at the Aria Resort and Casino in Las Vegas, MLB.com caught up with Arnold to discuss Castro’s new role.
MLB.com: What are your thoughts on the opportunity Cam is getting here with the A’s?
Arnold: He’s great. He’s one of the best. Very happy for him and his family. He’s a talented guy. His track record, if you ever look at what he’s been through as far as a coach in the Minor Leagues, a coach that coached all the way through the Rust Belt at junior colleges, it’s just a really cool story from where he’s come from to where he is today.
MLB.com: It does seem like kind of a unique path that Cam took to get here. How do you think that experience maybe helps in a GM role?
Arnold: He’s worn a lot of hats. He’s got a lot of empathy and he knows how to connect with players at every level. He’s been part of it as a coach. … He has that level of grind that it takes to be good in this sport.
MLB.com: He obviously comes from a long pitching background. How integral was he to that successful run of Brewers pitching we’ve seen in recent years?
Arnold: Super integral. He oversaw all our player development. We’ll certainly miss him, for sure.
