NORTH SOUND, Antigua – Zak Crawley’s second Test hundred left West Indies frustrated and facing a potentially precarious final day on Saturday, as the opening Test headed for a tense finish at the Vivian Richards Cricket Stadium.When rain forced a premature end to Friday’s penultimate day, the tourists were in a commanding position on 217 for one with the right-handed Crawley unbeaten on 117 and partnered by captain Joe Root on a typically compact 84.The pair came together in the first session after marquee seamer Kemar Roach hit debutant left-hander Alex Lees in front for the second time in the game, and have so far put on 193 for the second wicket to deflate West Indies on a placid surface.Crawley, who crafted a masterful 267 against Pakistan nearly two years ago, has so far punched 16 fours from 200 deliveries while Root chalked up his 54th Test half-century to continue his imperious march towards 10 000 runs in the longest format.
