Mascarenhas on form
Dimitri Mascarenhas produced his best bowling performance of the season to send troubled champions Nottinghamshire spiralling towards a heavy defeat at the Rose Bowl.
Mascarenhas finished with figures of 4-25 as Nottinghamshire, still without a win in the Liverpool Victoria County Championship this season, were bowled out for a meagre 147, handing Hampshire a healthy lead of 254.
Hampshire captain Shane Warne declined to enforce the follow-on and Hampshire, batting a second time, reached a formidable 148 for one at the close of the second day, a lead of 402.
Nottinghamshire began the second day brightly enough, snapping up the last five Hampshire wickets in an hour and for the addition of only 56.
John Crawley, 103 not out over night, added only another three in an innings totalling six hours before he was smartly held at second slip by David Hussey.
Charlie Shreck took four of the wickets to fall to finish with figures of 5-94, while new-ball partner Andrew Harris took 4-114.
Hampshire, 345 for five overnight, were disappointed to finish 401 all out, but that figure began to look gigantic as a sorry procession of Nottinghamshire batsmen made their way back to the pavilion.
Nottinghamshire lost eight wickets between lunch and tea with only Hussey offering any prolonged resistance in an innings of 25, which ended when he was lbw on the back foot to James Bruce.
But it was Mascarenhas who ripped through the major part of the Nottinghamshire batting by dismissing Jason Gallian, Will Smith, Chris Read and star batsman and captain Stephen Fleming for only 10.
Mascarenhas, who had previously taken only eight wickets all season, took all his wickets in a six overs spell and sad Nottinghamshire never recovered.
Bruce, Billy Taylor and Dominic Thornely each took two wickets while Warne allowed himself only one over, spending the rest of the innings at second slip masterminding
James Adams and Michael Carberry underlined Hampshire's desire for quick runs by putting on 52 for the first wicket before Carberry was held low at point by Smith off Shreck, but there was no let up on the Hampshire run rate.
Crawley carried on where he left off in the first innings by racing to his half century off 85 balls and Adams was not far behind, reaching his 50 in the last over by driving Graeme Swann through the covers for four.
At the end of a long and torrid day for Nottinghamshire, Hampshire batsmen Crawley was 63 not out and Adams unbeaten with 53.
