Div One: Tresco back in form

Marcus Trescothick registered a long-awaited century to boost Somerset's chances of toppling LV= County Championship Division One pacesetters Sussex on day two at Hove.

Trescothick, who last reached three figures in first-class cricket in September 2012, returned to form with an innings of 116 as Somerset posted 372 all out against Sussex's potent seam attack.

The Somerset skipper shared a 139-run partnership with South Africa batsman Alviro Petersen (76) for the fifth wicket and some late big-hitting from No 11 Lewis Gregory (47) kept Sussex waiting in the field.

Chris Jordan (5-76) maintained his excellent early-season form to deny Somerset maximum batting points, while Steve Magoffin chipped in with 2-63.

Sussex were forced to negotiate a tricky 11-over period before the close and in that time they lost in-form opener Ed Joyce to finish on 25-1.

At Lord's, Joe Root made 50 as Yorkshire gained the upper hand on day two of their clash with Middlesex.

Three for Finn

Root, captaining the side in place of Andrew Gale, made a fluent 63 to back up a fine morning's work from his bowlers, who had combined to dismiss Middlesex for just 123 in their first knock.

Ryan Sidebottom (4-34) and Jack Brooks (3-47) ran through the top order and Liam Plunkett, bowling sharply, helped mop up the tail to hand Yorkshire a 55-run lead.

Yorkshire extended that advantage 268 by the close with six wickets remaining thanks to the efforts of Root, Adam Lyth (54) and Kane Williamson (37) - all of whom were dismissed by Steven Finn (3-59).

The outcome of Warwickshire's clash with Nottinghamshire looks set to be decided with a day to spare after wickets continued to tumble at Trent Bridge.

The Bears collapsed from 46-1 to 152 all out to set Notts 300 for victory, Australian overseas recruit Peter Siddle (3-38) claiming three top-order wickets and Harry Gurney backing him up with 3-42.

Notts made a promising start to the run chase thanks to 64 from Phil Jaques, however Warwickshire edged ahead with two late wickets to restrict the hosts to 126-3 at the close - 174 away from victory.

An unbroken century partnership between Jos Buttler and Tom Smith rescued Lancashire from a perilous position against Northamptonshire on day two at Wantage Road.

The pair came to the crease with Lancashire struggling on 130-5 in their second innings - 85 runs ahead of Northants - but Buttler (66no) and Smith (44no) extended that advantage to 199 by the close.

Smith had earlier taken the two final wickets in Northants' first innings of 164 and then combined effectively with Buttler with the bat after Andrew Hall's three wickets had put the home side in charge.
