Victory in this tournament allowed Ireland to take part in the 2010 U-19 Cricket World Cup, where Dockrell made his Youth One Day International debut against South Africa U-19s.

Speaking of his aims, Dockrell said "My ambitions are to keep making progress with Ireland, but also to get into a county first team by developing all aspects of my game".

He featured in a single County Championship match, although his appearances in limited overs games were more frequent, playing in the semi-final of the Twenty20 Cup and the Champions Trophy.

[7] A side made up of some of the best players from Associate and Affiliate teams was put together to face England in Dubai in January 2012.

[8] Fellow left-arm spinner Murali Kartik left Somerset at the end of the season, giving Dockrell the opportunity to establish himself in the team.

In Somerset's opening match of the 2012 County Championship Dockrell took 6/27 in the second innings against Middlesex to help his side to a six-wicket victory.

[11] Dockrell was the leading run-scorer and wicket-taker in the 2018 Inter-Provincial Cup, scoring 231 runs and taking ten wickets in the tournament.

For the 2010 ICC World Twenty20 Qualifier and the 2010 Quadrangular Twenty20 Series in Sri Lanka, young spinners Dockrell and Gary Kidd were chosen.

After Impressing in the 2010 ICC World Twenty20 Qualifier, Dockrell was selected in the Ireland squad for the 2010 ICC World Twenty20, playing a starring role as the tournament's youngest player, taking four wickets against the West Indies and troubling Kevin Pietersen in a tight bowling display in the abandoned encounter with England.

[6] He was forced to miss Ireland's ODI encounter with Australia on 17 June 2010 because he was sitting a Biology exam in the Leaving Certificate.

[26] In September 2019, he was named in Ireland's squad for the 2019 ICC T20 World Cup Qualifier tournament in the United Arab Emirates.
