PRAGUE: Defending champion Czech Republic will be without its two highest-ranked players — Petra Kvitova and Lucie Safarova — in next week's Fed Cup semifinals at Switzerland. Kvitova and Safarova were key members of the Czech team that won four Fed Cup titles in five years. But the No.7-ranked Kvitova has been struggling since she terminated her seven-year partnership with coach David Kotyza in January, and the 15th-ranked Safarova needs more time to return to form following last year's illness. No.18 Karolina Pliskova, who won both singles matches and the doubles in the 3-2 victory at Romania in the first round, will lead the Czechs for the April 16-17 series on an indoor hard court in Lucerne. Barbora Strycova, Denisa Allertova and Lucie Hradecka were also included in the team.
