So it's not surprising that Mendoza was able to hold the Rangers to one run in four innings. Harrison was the reverse, giving up four runs in one inning as the Royals defeated the Rangers, 7-5, on Sunday at Surprise Stadium.
Mendoza threw 65 pitches, allowing four hits and a walk while striking out two. He was primed by a 107-pitch performance in the Caribbean Series, where he was the Most Valuable Player for the champion Mexico team.
"I'm coming from winter ball and it feels good," Mendoza said. "The wind was so bad but I just tried to let the sinker move by itself. I tried to throw in the middle and get ground balls."
Harrison, pitching on a raw spring afternoon, allowed six hits to nine batters while throwing 40 pitches. Game-time temperature was 56 degrees, with 20-30 mph winds blowing in hard from left field.
"It definitely wasn't ideal conditions but I've pitched in worse," Harrison said. "You can't let it affect you. I couldn't put guys away or make pitches when I had to. It seemed like every time I got ahead I would let a guy get back in the at-bat. I was having trouble making quality pitches down in the zone."
Royals catcher Salvador Perez had three singles and right fielder Jeff Francoeur had a triple and a single in three at-bats. Rangers second baseman Leury Garcia was 2-for-3 with a two-run home run while center fielder Leonys Martin added two hits.
Up next: For the first game against a team other than Texas, Kansas City is going with primarily Minor League pitchers against the Arizona Diamondbacks on Monday, starting at 2:05 p.m. CT at Surprise Stadium. Left-hander Chris Dwyer, whose four-year career has been marked by a sharp curveball and command issues, will start. Cuban lefty Noel Arguelles, who signed for $7 million in 2010 and then underwent shoulder surgery, is also scheduled. J.C. Gutierrez, the D-backs' closer for parts of two seasons, will pitch against his former club. He's contining his comeback from Tommy John surgery in 2011.
