KANSAS CITY -- Right-hander Kyle Davies' injury led to not only a 19-1 loss to the Indians on Monday night, but also to some roster moves.
Right-hander Vin Mazzaro was optioned to Triple-A Omaha and left-hander Everett Teaford was called up from Omaha. Mazzaro returned to the Minors after giving up 14 runs in a 2 1/3-inning relief outing.
Initially, the Royals announced that Davies was being placed on the 15-day disabled list and that reliever Robinson Tejeda was being recalled from his injury rehabilitation assignment. But that announcement was quickly rescinded because the club decided to delay a decision until receiving results from Davies' MRI exam of his ailing right shoulder.
Anything official would wait until Tuesday, before the series finale against the Indians.
Teaford has a 2-1 record and 3.04 ERA in 10 games for Omaha, but only three outings have been starts. He's been pitching in the bullpen recently in case the Royals needed another lefty in relief. He's been throwing strikes, with 24 strikeouts and six walks in 26 2/3 innings.
Tejeda, on the disabled list since April 13 with a right shoulder ailment, has pitched in five games for Omaha without allowing an earned run in six innings. He's allowed one unearned run and five hits, with six strikeouts and two walks.
Mazzaro, who had a rocky four-inning start last Wednesday in New York -- he gave up just two runs but threw 94 pitches -- left the Royals with a 22.74 ERA. He gave up 16 runs, 17 hits and seven walks in 6 1/3 innings.
Originally, Mazzaro had been scheduled to start Tuesday night's game against the Indians.
Davies' start for the Royals on Monday night lasted just four batters and he walked three of them.
With that, he motioned to the dugout and brought out head athletic trainer Nick Kenney, manager Ned Yost and pitching coach Bob McClure. Within a minute, he was headed for the clubhouse with what was reported as interior soreness of the right shoulder. He will undergo an MRI exam and be reevaluated on Tuesday
Davies left the bases loaded with Indians. Michael Brantley walked to start the game. Asdrubal Cabrera's sharp grounder was snagged nicely by first baseman Eric Hosmer, who got a force out at second before Cabrera beat the return throw. But Davies walked both Shin-Soo Choo and Carlos Santana to end his outing.
He threw 21 pitches, and just six were in the strike zone.
Rookie Nate Adcock, the Royals' designated long man in the bullpen, took over and caught Travis Hafner looking at strike three. Orlando Cabrera hit a single into short right field to score two runs, but Santana was caught rounding second base and was out in a rundown. For a moment, second was left unattended, but Hosmer alertly rushed over to take Wilson Betemit's throw and tagged Santana for the third out.
The two runs were charged to Davies, who came out of his ninth start with a 1-6 record and 7.46 ERA.
