London Wasps have announced they will sign London Irish scrum-half Jack Moates at the end of the season.
The 20-year-old, who had a loan spell at London Welsh in 2011-12, has made 17 appearances for the Exiles this season.
Wasps director of rugby Dai Young said: "I have been impressed with Jack as a young scrum half and I know he is a very ambitious player.
"A squad needs a strong mix of scrum-halves and he will add to the likes of Joe Simpson and Charlie Davies."
Moates added: "There are already some high quality scrum-halves at Wasps, but I am looking forward to developing further under the likes of Dai Young and Shane Howarth, so that I can challenge for a place in the first team."
