Lucknow: Suresh Raina, whose century in the second ODI helped India regain its confidence back after successive defeats in Tests against England, has extensively worked hard on tackling short pitch deliveries in the hockey turf at Guru Govind Singh Sports College here, his coach Deepak Sharma said.

Sharma said before leaving for England tour, Raina sweated out on the astroturf ground of the Guru Govind Singh Sports College to work on this grey area.
