Rios was playing in his first Cactus League game with the Royals after spending 2014 with the Rangers. He ended up going 2-for-3 with three RBIs. Hosmer, Morales and Dyson also had two hits. Rios said he took no extra solace in doing that against his old teammates.
"No, it doesn't matter who it was against," Rios said. "It's just important to get my timing down. That was a good start for us."
Lewis retired three straight hitters after Rios' home run and left the game having thrown 35 pitches. Lewis said he spent most of his time working on his fastball, especially in counts that normally call for secondary pitches.
"I felt great, I threw a lot of strikes," Lewis said. "Overall I felt great. I got what I wanted out of it. The results weren't what I wanted, but it is what it is. First outing, I threw  pitches in one inning and I didn't feel any fatigue. The arm strength is good."
Royals rookie starter Aaron Brooks, part of K.C.'s rotation depth, allowed one run in two innings. The run came on a home run by Ryan Ludwick in his return to action in a Rangers uniform. Brooks allowed two hits, did not walk a batter and struck out one.
Yovani Gallardo entered in the third inning and was charged with four runs allowed in 1 2/3 innings pitched in his first game action with the Rangers. Gallardo threw 42 pitches in the outing.
Prince Fielder started at first base and batted cleanup for the Rangers. It was the first time he has been in a game of any kind since last May 16, and he went 0-for-2 Wednesday. He grounded out to first base and popped to left field.
Up next: The Royals will get a look at 6-foot-7 left-hander Brian Flynn, acquired in the Aaron Crow trade last fall, when they host the Rangers at 2:05 p.m. CT on Thursday in Surprise. Fans also will get a peek at two of the club's top pitching prospects -- left-hander Sean Manaea and right-hander Miguel Almonte. The game can be heard on MLB.com Gameday Audio.
