The 18-year-old academy graduate scored 59 on his first-class debut against Hampshire in the final game of 2014 and following the completion of his A-Levels earlier this summer, made regular appearances for Glamorgan before narrowly missing out on a maiden Championship century with a career-best 98 against Gloucestershire in the last match of the 2015 season.
Donald will now spend the winter at the Darren Lehman Cricket Academy in Adelaide in a bid to hone his burgeoning talent.
“I’m delighted to be signing my first full-time contract with my home county,” said Aneurin.
“I’ve learnt a lot from being in the 1st team dressing room and playing alongside the senior players in the squad this season and now I’ve got a great opportunity to develop my game and focus on my cricket.
“Andrew Salter has told me what a good experience it is out in Adelaide at the Darren Lehman Academy, so I’m looking forward to being out there until February and with full preparations under my belt, hopefully I can keep on playing first-team cricket for Glamorgan regularly and help the Club win more games next year.”
Glamorgan Chief Executive Hugh Morris has high hopes for Donald who captained England Under 19s throughout their five-match One Day Series against Australia in August.
“Now Aneurin has finished his studies, we are delighted to welcome him onto our playing staff as a full-time professional,” said Hugh.
“He is an exciting talent and we are grateful to the ECB for supporting his development with this scholarship opportunity at the Darren Lehman Academy. I believe Aneurin has the ability to enjoy a long and successful career with Glamorgan.”
Glamorgan are also delighted to confirm three other Academy graduates have signed new contracts to stay with the Welsh county.
Seam bowler Dewi Penrhyn Jones has signed a one year professional contract, whilst Jeremy Lawlor, and Jack Murphy have all signed new one-year development contracts with the Welsh county.
Paceman Dewi made his first-class debut for the club in September, taking 3-55 in the rain-affected draw against Northamptonshire, following earlier appearances in List A matches against Middlesex and Lancashire Lightning.
2013 Academy player of the year Jack Murphy made his first-class debut against Glamorgan playing for Cardiff MCCU in April, but a couple of niggling injuries throughout 2015 restricted his appearances.
Batsman Jeremy Lawlor also had his first taste of first-class cricket for Cardiff MCCU against Glamorgan, before going onto make his first-class debut for the Welsh county at The SSE SWALEC against Kent in the final home game of 2015 season.
Chief executive Hugh Morris said: “We are delighted that Dewi Penrhyn-Jones, Jack Murphy, Jeremy Lawlor and Aneurin Donald have signed new contracts with Glamorgan.
“These young Welsh players have all progressed from our development programme to make their first-class debuts.
“It is a strategic objective of the club to identify and develop the next generation of Welsh players and these home-grown cricket talents are all capable of succeeding and achieving honours for Glamorgan.”
