Middlesex finished in a strong position of 320/3 at the end of day one of their LV= County Championship match with Sussex thanks to a century from skipper Chris Rogers.
Rogers struck a fine 161 not out in glorious Lord's sunshine which beat down on the ground all day.
He will have been thankful that his opposite number Ed Joyce decided to insert the home side after winning the toss, a decision he may now be questioning.
Sussex, who have England's Matt Prior in their side as he's not required in England's ODI outfit, let the Aussie opener off twice.
Both times being put down in the slips, once when he was on just three and the second after he had notched up his century.
The 35-year-old was ably supported by his fellow Australian opener Sam Robson who hit 54 before being trapped lbw by spinner Will Beer, who took 2/55 from his 21 overs.
Beer cleaned bowl Joe Denly, who fell for a disappointing 11 as his mixed form with the bat continues.
Chris Nash picked up the seaside county's only other wicket of the day removing Adam London - who was in the side in place of Dawid Malan - for 18.
Club captain Neil Dexter finished the day unbeaten on 62 not out as the home side made sure that they gave the division leaders nothing on a day which finished with long shadows across Lord's as play came to a close just after 7pm.
