COUNTY CHAMPIONSHIP DIVISION ONE, Headingley
Yorkshire v Worcestershire
28 April-1 May (Play starts 1100 BST)
CLOSE OF PLAY, DAY ONE (rain stopped play): Yorkshire 123-1
Vaughan faced just two balls before the rain came at Headingley
Michael Vaughan was denied by the weather as he missed a last chance to make an impression before Wednesday's naming of England's Test squad.
Vaughan faced just two balls against Worcestershire at Headingley as rain wiped out almost half the day's play.
Yorkshire were limited to 123-1, Jacques Rudolph making an unbeaten 73.
Two youngsters made Championship debuts for the visitors, Alex Kervezee, 19, and second teamer David Wheeldon, 20, called in for the injured Ben Smith.
Smith, who had damaged the little finger of his right hand going for a slip catch in Sunday's FP Trophy win over Ireland in Belfast, had hoped to be passed fit to play.
But he was still in too much pain and discomfort from it, necessitating the call for Wheeldon to travel up from Worcestershire on Tuesday morning.
Wheeldon is also registered to play for Staffordshire, for whom he played in the MCCA Knockout Trophy against Suffolk at Audley on Sunday.
And he had three separate visits to the crease against Yorkshire last week for Worcestershire on second team duty, making 12 in the Trophy and then 31 and 10 in the two sides' three-day Championship game at Kidderminster.
It was Yorkshire's turn on the first day of this game. And, after being put into bat in cool and overcast conditions by visiting skipper Vikram Solanki, the home side made a solid start.
They claimed their first century partnership for the first wicket since Craig White and Joe Sayers put on 177, also against Worcestershire at Headingley, almost exactly two years ago.
Again, the workmanlike Sayers was involved in this one, helping fellow left-hander Rudolph put on 123 in 46 overs.
Yorkshire had to take care against a good new ball spell from Ashley Noffke and Matt Mason.
And, just as he did two years ago, Sayers enjoyed an early life on 3 when Moeen Ali put down a bat/pad chance off Mason at short leg.
On that occasion, Sayers went on to make a century but this time it was a less expensive miss.
Worcestershire made their first breakthrough just before the early end of play in mid-afternoon when, with the light deteriorating fast, Sayers, on 49, attempted to hook his way to a half century but top edged Chris Whelan to keeper Steven Davies.
Vaughan then only had time to face two balls before the rain set in and ended play for the day with the score unchanged.
With Adil Rashid away on England Lions duty, Yorkshire brought in left-arm spinner David Wainwright and also preferred all-rounder, Ajmal Shahzad, to paceman Deon Kruis.
Worcestershire's Ben Smith told BBC Hereford & Worcester:
"I hurt the finger going for a slip catch on Sunday and I'm very disappointed not to be playing.
"But it gives the opportunity to a couple of the young lads to step up and maybe make a mark.
"I'm hoping I'll be fit for Monday's Friends Provident Trophy game against Nottinghamshire at New Road."
