SURPRISE, Ariz. — Yu Darvish struck out four in two innings of the spring opener for Texas, and Prince Fielder hit a towering solo homer as the Rangers beat the Kansas City Royals 11-7 on Thursday.Darvish, who led the majors with 277 strikeouts and was second in the AL Cy Young Award voting last season, threw 23 of 29 pitches for strikes. His first pitch to all eight batters faced was a strike.“I think it worked out very well,” Darvish said through his interpreter. “I’m looking forward to tomorrow’s pitchers meetings and I think (pitching coach Mike) Maddux is going to praise my performance. ... There’s a lot of life to my fastball, a lot of movement on my slider.”The Rangers struggled at times last year to score runs behind Darvish, who was the first pitcher since 1989 to have four 1-0 losses in the same season.“Hopefully we can turn that around,” Fielder said.Texas led 4-0 before Darvish’s final pitch in the Cactus League opener, and never trailed.Fielder, acquired in a trade from Detroit for Ian Kinsler, had a weak grounder in the first inning.
