"I value school, and it took a bit for me to understand … it's a risk going with baseball and not finishing school," Staumont said. "I'm very confident that with some hard work, I can do well and make my mark on baseball."
Staumont, 21, is the 28th signee of the Royals' 41 drafted players and the only one of the team's top three picks.
Both first-round picks -- right-handers Ashe Russell and Nolan Watson -- remain unsigned.
"I value how they treat their players," Staumont said of his new club. "They make a huge emphasis to treat them with respect and give them the best opportunities and resources to make them better. You can't ask for anything better in this position.
"It's a long road, and they make it as easy as possible to hone your skills and eventually make that 40-man [roster]."
Coming from Azusa Pacific University, the right-hander throws a mid-90s fastball that touches 100 mph, while turning to a power breaking ball as a second pitch.
Scouts reported prior to the Draft that Staumont's biggest issue comes from inconsistent command, which showed in his team-leading 54 walks this spring.
"Everyone talks about command, but I would want to say that comes with maturity," Staumont said. "As you develop over the years and throw harder, there are just simply maturity and tweaks here and there that will change, and my game will change as well."
Staumont also struck out 109 on the season with 14.29 strikeouts per nine innings, second best in Division II baseball. He also posted a .155 batting average against.
"I believe that the most successful players are those that use their physical strength combined with their mental approach to it," Staumont said. "Everyone knows that there are plenty of mid-90s fastball players that never make it.
"The Draft is only a stepping-stone. I've got a lot of work to do, and I couldn't be with a better organization."
