"He swung the bat real well down there in his rehab stint, his ankle's back to 100 percent and he has all his mobility back," manager Ned Yost said.
Betancourt came off the disabled list after missing 26 games with a sprained right ankle that he sustained initially in Spring Training. Yost got him back in action immediately playing second base and batting second on Friday night against the Athletics.
Betancourt went 1-for-4, but delivered an RBI double to spark a two-run first that helped the Royals earn a 2-0 win.
To make room, infielder Irving Falu was optioned to Triple-A Omaha after making a good impression in his 28-day stay filling in for Betancourt and later for Chris Getz, who also went on the disabled list. Falu, a switch-hitter, played in 12 games including five starts at second base, three at third and one at shortstop and batted .326 (14-for-43).
"He did very well for us, I'm very pleased with the job that he did up here," Yost said. "I expect we'll see Irving Falu back here in the big leagues again."
The Royals opted to keep Johnny Giavotella on the roster instead of Falu.
"Johnny's got a better bat off the bench for us right now," Yost said. "Yuni and Falu are kind of like the same players -- they're both utility guys that can play multiple positions and we've got that in Yuni. If we need to move him to third or short, we're covered there. And we like Johnny's bat from the right side late in the game."
Betancourt, also a right-handed batter, had a .280 (14-for-50) average in 15 games when he went on the DL, but was .348 (8-for-23) with runners on base. In a combined six Minor League rehab games for Northwest Arkansas and Omaha, Betancourt was 10-for-23, .435, with two homers and six RBIs.
