Calcutta, Nov. 21 :    Calcutta, Nov. 21:  Tripura 170 & 104/7 Bengal 458/4 dec. Tripura, staring at an ignominious innings defeat, limped to 104 runs for seven, after Bengal, riding on skipper Devang Gandhi's unbeaten double century, declared their innings at 458 for four on the penultimate day of the Ranji Trophy league tie at Eden Gardens today. Tripura, who were bundled out for a paltry total of 170 in the first innings, still require 184 runs to force the hosts to bat again. Bengal bowlers, notably two debutants Shib Shankar Pal and Sujoy Parui, stuck to an accurate line with the new ball, giving almost no opportunity for Tripura openers to relax. The breakthrough came in as early as the seventh over when Tripura captain Sourav Dasgupta found no answer to a rising delivery of Pal. The promising medium pacer also accounted for Rajib Deb Barman. Laxmi Ratan Shukla, used as first-change bowler, struck in quick succession. Pranob Debnath, looking to drive, edged to Utpal Chatterjee in the slips, while Chetan Sachdev got out for naught, chasing a ball well outside the off-stump. With wickets falling at regular intervals, the visitors never appeared strong enough to put up much of a resistance. That the highest partnership so far in their second innings is 22 (between Deb Barman and Mridul Gupta, and Subol Chowdhury and Gourpada Banik) also implied how one-sided the battle has been. Both spinners - veteran Utpal Chatterjee and young Wrichik Mazumder maintained a tight line, jointly accounting for three Tripura batsmen. Parui's skill of beating batsmen outside the off-stump at will, however, went unrewarded. He gave Tripura wicketkeeper Rajib Dutta some frightful moments, hitting the latter twice, at the fag end of the day. But Bengal had only themselves to blame for allowing Tripura to survive the day as the home team dropped as many as four catches and failed to claim at least half a dozen half-chances. Wicketkeeper Saba Karim, whose list of victims (now 203 with 161 catches and 42 stumpings) crossed the coveted 200-mark in the match, however, was the main culprit. The way he dropped a couple of catches and found difficulty in gathering balls behind the wicket today, should give the Bengal selectors a point to ponder on. Going by his performance in this match, it is apparent he is yet to recover fully from his eye injury. 'My eyes are OK. What I need is more match practice to get my eyes adjusted to the situation,' Karim, however, explained later. Earlier, the Bengal skipper made a mincemeat of hapless Tripura bowling. Gandhi, who resumed his innings at 128, was in a plundering mood and reached his fourth double centuries in Ranji Trophy in just 272 balls. He effected 27 hits to the rope and three sixes. Bengal declared their innings at 458, losing the wicket of Karim (22) soon after Devang crossed the significant mark. He, however, refused to bracket the innings as his best in the domestic league. 'I'm pleased with my performance. But my best knock still remains the one I hit for India A earlier,' he said.
