Rest of India's bowling unit performed like a well-oiled machine as the team thrashed Madhya Pradesh by 238 runs to retain the prestigious Irani Cup here on Sunday. Chasing a near-impossible 437 for victory, MP were bowled out for 198 in 58.4 overs as the match ended during the opening session of the fifth day. With the so-called result-oriented and under-prepared pitches for the ongoing Border-Gavaskar Trophy receiving a lot of flak, the Gwalior track was a throwback to the days when there used to be help for every department of the game. There were four tons scored in the match, 40 wickets fell and pacers and spinners had equal say during the course of the game.
