Junis, the team's No. 4 or No. 5 starter, tossed four no-hit, scoreless innings in his second spring start. He walked none and struck out seven as the split-squad Royals rolled over the Padres, 4-0, at Surprise Stadium.
Junis had excellent fastball command, and his normally wipeout slider also was spot on. He's also trying to improve his changeup and his curveball, the latter with a new spike grip that makes the break more vertical.
"Salvy's a lot like [Alcides Escobar]," Yost said. "They want to play every day. They love baseball so much they want to play all the time."
Perez clocked a solo homer, his third long ball of the spring, on Friday vs. San Diego.
Camp battles • Non-roster outfielder Michael Saunders, trying to wedge his way onto the 25-man roster, helped his chances with a three-run double in the third inning on Monday. He now is hitting .304 with two doubles and six RBIs.
• Right-hander Blaine Boyer, another non-roster invitee, is trying to make the 25-man out of the bullpen. He came into the sixth inning with two on and two out and induced a pop fly to short right field before working a perfect seventh. He has yet to give up a run this spring.
Injury update • Infielder Adalberto Mondesi was back in the lineup on Monday at DH. Mondesi will still be on a no-throw program to rest his right shoulder impingement for two to three more days.
• Outfielder Paulo Orlando remains out with a strained hamstring. Yost said he would not be out for an extended period.
• Center fielder Bubba Starling is expected to be out of action for an extended period, Yost said, because of an oblique injury. Yost also said Starling could be a candidate for the disabled list.
Up next Left-hander Danny Duffy will make his third spring start for the Royals when they play the A's on Tuesday at 3:05 p.m. CT at Surprise Stadium. Duffy is expected to throw 60-65 pitches. Also expected to throw are right-handers Kelvin Herrera, Brandon Maurer, Wily Peralta, Kevin Lenik and Josh Staumont along with lefty Tim Hill. Listen on Gameday Audio.
