Sheffield’s Billy Root began confidently on his county debut for Nottinghamshire, forcing the ball to the ropes on six occasions in his 37 in the Division One match against Hampshire at Trent Bridge.
The left-hander, younger brother of Yorkshire and England’s Joe Root, appeared unfazed by the situation until an edge from Gareth Berg was smartly taken by Ervine, who responded to the ball rebounding out of James Vince’s hand at second slip.
A century from Riki Wessels enabled Notts to take the upper hand as Hampshire fought hard to preserve their top-flight status.
Wessels scored 104 to help the hosts make 340 after being put in, with Fidel Edwards returning figures of six for 88.
Half-centuries from Gary Ballance and Adil Rashid helped Yorkshire to 241 for seven on a rain-hit day one of their clash with Sussex at Headingley.
The White Rose wobbledon 108 for four at lunch. Ballance top-scored with 55 for the county champions but once he departed, a partnership of 72 between Jack Leaning (36) and Rashid (53) helped thwart Sussex, who need a draw to be sure of avoiding relegation.
