The two pacemen tore apart the Kent batting in their fiery first spells as the second string Bangladesh side, who were all out for a moderate 185 after electing to bat first at the St Lawrence Ground in Canterbury, reduced the home side to 75-7 shortly before close of play.

Speedster Shahadat clean bowled O'Brien to give the visitors an early breakthrough and Russel joined the party soon as Kent crashed to 15-4, losing three top batsmen on the same total.

After sharing the first four wickets evenly, left-handed Russel took two more wickets with Kent on 40. Russel's figure was 4-27 from nine overs and Shahdat's 2-14 from seven. The remaining wicket to fall went to Talha Jubair.

Earlier, Tushar Imran continued his impressive run in the tour to salvage Bangladesh A to 185 with a strokeful 86. Having lost opener Nafees Iqbal with just three runs on board, one-down Tushar put on 59 runs for the second wicket with skipper Shahriar Nafees (30) to repair the damage.

However, Alok Kapali and Mehrab Hossain's departure on the same score of 84 once again put Kent on the top.

Tushar, who cracked 16 boundaries in his 90-ball knock, did not break under pressure and maintained his assault during another half-century stand with Nazim-uddin, whose 27 was the only other double-figure in the innings.

In-form Tushar, who has scored two first-class centuries in the tour so far, was the fifth man out and his teammates managed to add only 26 more runs before Martin Saggers mopped the tail, finishing with 5-48 from 14 overs.
