Roston Chase got some of his groove back with a resolute half-century, but an attempt by West Indies to forge ahead against Zimbabwe in the second Test on Monday was again thwarted by their opponent’s tenacity and fickle weather.Chase has top scored so far for the Windies with 70, and when rain stopped play for the second time about 45 minutes before the scheduled close on the second day at the Queens Sports Club, the Caribbean side was 290 for eight, a first innings lead of 165.The Barbadian slow bowling all-rounder shared successive half-century stands with compatriot Kyle Mayers and wicketkeeper-batsman Joshua da Silva to fortify the Caribbean side’s grip on the match.Da Silva scored 44 and Mayers made 30, but they were two of four wickets that West Indies conceded during the 49.4 overs of play that were possible on the day.Pacer Victor Nyauchi ended play with 3-56 from 16.4 overs, and leg-spinner Brandon Mavuta supported with 3-73 from 24 overs.
