Steven Finn boosted his claims for an England Test recall with three wickets as Middlesex completed a County Championship win over Sussex.

Finn followed up his three first-innings wickets with three for 66 as Sussex were bowled out for 225 in their second innings. That left Middlesex with a victory target of 18 and they completed a 10-wicket win 40 minutes after tea on the final day.

Middlesex looked like wrapping up victory early when they reduced Sussex to 101 for five before lunch.

They were delayed by Ben Brown's second half-century of the match but when he and Naveed Arif, who had put on 62 for the seventh wicket, departed in successive overs Sussex were heading for their second successive Championship defeat.

Finn, who had already picked up Ed Joyce on the third evening, was taken for two fours by Chris Nash in his first over of the day but hit back in the next when he cleaned up the Sussex opener with a leg-stump yorker.

Finn struck again when Murray Goodwin was smartly taken low down at second slip by Ollie Rayner. It was Goodwin's ninth single-figure score in 11 innings this season with Finn completing his first six-over spell with two for 29.

There was no respite for Sussex when Gareth Berg replaced Finn at the Pavilion End. Joe Gatting was leg before in his first over and then Finn got in the act in the field, holding a two-handed catch when Luke Wright chased a wide ball from Berg and slashed to gully.

Skipper Mike Yardy also got out to a poor shot, pulling a short ball from Toby Roland-Jones straight to deep square leg.

Finn returned after lunch and should have been celebrating again when Arif was badly dropped in the gully by Morgan on nought. He eventually got off the mark with a boundary off the 34th ball he faced and gradually Sussex's seventh-wicket pair mounted a recovery of sorts.

Brown twice pulled Roland-Jones for two of the eight boundaries he collected in a two-hour 53 as he and Arif added 63 in 25 overs, seven of which were bowled by Finn at a cost of just five runs.

Just when Middlesex were getting frustrated Berg went round with wicket to have Arif well caught low down at slip by Dawid Malan and in the next over Brown, having reached his 50 off the previous ball, mis-judged a reverse sweep at off-spinner Rayner and gave a simple catch to slip.

Steve Magoffin enjoyed himself either side of tea with 37 including six fours and a six off Malan, but the occasional leg-spinner picked up the last two wickets with Magoffin and Monty Panesar holing out.

That left Middlesex with 18 runs to win, a task openers Sam Robson and Chris Rogers completed in 3.5 overs as Middlesex added to their earlier wins at Lord's against Surrey and Worcestershire.
