Div One: Yorks skittle Notts
Yorkshire will be looking to capitalise on a fine bowling performance which saw them dismiss Nottinghamshire for 205 on a rain-affected opening day of their Division One match at Headingley.
The White Rose county, who drew level with Middlesex at the top of the table courtesy of their five bowling points on day one, reached 52-2 in their reply before the weather ended play prematurely.
The hosts had their opponents 139-8 at one point before some impressive late hitting from Peter Siddle and Luke Fletcher guided Notts to 205 all out.
Siddle then removed both Yorkshire openers in an impressive opening spell but Jack Leaning (23no) and captain Andrew Gale (16no) steadied the ship before the rain fell.
Tim Bresnan finished with 3-43 off 16 overs while Jack Brooks was slightly more expensive in taking 3-74, including James Taylor (3) and Samit Patel (0) in the same over, in front of England selector James Whittaker.
Third-placed Somerset will also have their sets sight on top spot by the end of the week and they made a promising start by reducing Sussex to 210-9 on day one at Taunton.
Sussex skipper Ed Joyce faces a restless night's sleep after rain saw him end the day unbeaten on 99 and with just Steve Magoffin (1no) for company.
Ireland international Joyce, who has already made three Division One centuries this season, held firm as Somerset continued to take wickets at regular intervals.
All-rounder Peter Trego claimed 3-47, while Alfonso Thomas (2-63) and Craig Overton (2-41) shared four wickets.
Joyce found the boundary on 12 occasions and was denied the chance of an opening day century as 12 overs were lost to the rain.
Lancashire closed in trouble on 188-6 against Warwickshire after New Zealand spinner Jeetan Patel took 3-52.
Alex Davies, recently promoted to open the batting, top-scored with 59 and put on 78 with Andrea Agathangelou (31) but England limited-overs wicketkeeper Jos Buttler was dismissed for a duck.
