The 27-year-old entered Friday's series opener against the White Sox hitting .300 with a triple and three stolen bases in 10 games since taking over the position.
Royals manager Ned Yost said Dyson's showing while Lorenzo Cain is on the disabled list with a left groin strain isn't "do-or-die" for Dyson's future, but the club is using the time to evaluate Dyson, who the organization chose in the 50th round of the 2006 First-Year Player Draft.
So far, so good, the manager said.
"He's done great," Yost said. "He's worked really hard on the adjustments that we've asked him to make, and he's been productive. He's been fine in the outfield and he's been great on the bases."
