All eyes were fixed on former Australia captain Steve Smith when he batted for English county Sussex for the first time, in their Division Two match at Worcester.

Smith's three scheduled Division Two appearances ahead of this summer's Ashes have raised eyebrows, and he was soon in the firing line after the visitors lost two quick wickets on the second morning.

Just as he was finding some rhythm on Friday, though, Smith fell for 30 to a debatable lbw call off the bowling of Josh Tongue.

Smith had faced a dozen deliveries without scoring, but he duly took advantage from his 13th ball - short and wide from Ben Gibbon - to get off the mark by cutting for four.

He looked to be warming to his work by clipping then pulling Tongue for leg-side fours but he was perhaps unfortunate the umpire's finger went up after being struck well above the knee roll while already on his toes.

It was left to Sussex captain Cheteshwar Pujara to score a fine 136 in Sussex's 373 all out. Worcestershire reached stumps on 1-34 - trailing by 75 heading into day three.

If Smith played second fiddle to Pujara at Worcester, the day's star performance came from Australian fast bowler Michael Neser at Headingley.

The 33-year-old, left out of this summer's Ashes touring party, showed the selectors what they could be missing as he claimed career-best figures of seven for 32 off 11 overs to help skittle Yorkshire for 106.

He also took the spotlight away from the returning Jonny Bairstow, who made made an unbeaten 20 in his first competitive innings after more than eight months out injured.

But he could only watch on from the non-striker's end as Neser ripped through his colleagues at Headingley.

Boasting a first-innings lead of 139, Glamorgan reached 2-57 in their second innings before the weather brought play to an early finish.
