Dexter and Robson star for Middlesex
Half-centuries from Neil Dexter and Sam Robson helped lift Middlesex to 306 in reply to Worcestershire’s 323 in the weather-hit LV= County Championship Division One match at New Road.
Dexter led the way with 90 and featured in a century stand for the fourth wicket with Robson, who made 72.
Relegation-battling Worcestershire were again being well served by paceman Alan Richardson's 4-62.
By the close, the hosts led by 61 on 44 for the losses of first-innings centurion Daryl Mitchell, Phil Hughes and Moeen Ali.
Dexter, who scored 101 against Warwickshire at Edgbaston last week, and Robson produced key performances for Middlesex after Richardson had wasted little time in unsettling his former club when they resumed on 49 without loss off 13 overs.
He launched a burst of three wickets in successive overs, costing just four runs, by having left-hander Chris Rogers caught by young wicketkeeper Ben Cox for 22.
Joe Denly soon followed, bowled off stump, before Richardson picked up his 50th championship scalp of the campaign by removing Dawid Malan.
Richardson’s impressive treble left Middlesex on 61 for three and in need of a steadying influence which Robson provided after resuming on 27 not out.
Accompanied by Dexter, he completed his half-century off 108 balls with nine fours and, by lunch, the duo had steered Middlesex to 140 for three.
Both continued to prosper after the break and completed a well-earned century stand in 32 overs.
Robson, dropped the previous evening on 21, finally fell after hitting 11 fours off 157 balls in his highest championship score so far this season. He put on 106 in 34 overs with Dexter, who registered his half-century in the process.
Robson, whose father Jim played for Worcestershire’s second XI in 1979, perished when he dollied up a catch to Matthew Pardoe at forward short-leg off spinner Moeen.
Adam Rossington was trapped lbw by Gareth Andrew before Dexter and Gareth Berg pushed Middlesex past the 200 mark in the 63rd over.
By tea, taken one ball early because of a brief shower, they had completed a half-century stand with Middlesex on 241 for five.
The first delivery after the interval, however, ended the 60-run partnership when a loose drive outside the off stump led to Berg being caught at first slip by Moeen off Chris Russell.
Dexter finally departed to an inside edge on to his middle stump against Joe Leach after hitting 12 fours off 190 balls.
Worcestershire continued to pep their fortunes when Richardson ousted Toby Roland-Jones before Russell saw off Steven Crook and Tim Murtagh after the last two Middlesex wickets had yielded 41.
