Navarro was obtained last Saturday, along with Minor League pitcher Kendal Volz, in a trade that sent infielder Mike Aviles to the Red Sox.
"[Navarro's] 23 years old and he needs to play. If he was 28 or 29 years old, it'd be a different story -- we'd be more set in our mind to allow him to be a utility-type player," manager Ned Yost said. "But he's 23 and he's got some upside tools that continually need to be developed. The only way you're going to do that is by playing."
Navarro will have that chance with the Storm Chasers because the Royals' infield is set with Mike Moustakas at third base, Alcides Escobar at shortstop, Eric Hosmer at first base with Giavotella moving into second base and Chris Getz filling the backup role.
Yost said that Navarro will likely play all over the infield, including his natural position of shortstop.
But the Royals don't want to cast Navarro as a utility player.
"Not at 23 years old, no. That's for sure. You want to try and give him every opportunity to show that he's an everyday player, too," Yost said.
Navarro played in two games for the Royals at third base and went 3-for-7 with a double. Including 16 games for the Red Sox, he batted .250 with one home run and six RBIs.
