On 4 August 2022, Lyng was appointed manager of the Kilkenny senior hurling team.
David Herity endorsed Lyng's appointment as Brian Cody's successor, telling Off the Ball AM that Lyng would be a different type of manager: "Derek would be nothing like Brian... Derek was always seen as one of the lads in the dressing room Brian approached before a match and gave a dig to and said, 'right get these lads going'. He was that kind of lad, along with a Noel Hickey or Henry Shefflin. He would have ticked a few boxes in what Brian Cody would look for in a player and leader. When Derek came in as, he was slightly the yin to the yang. James McGarry and Brian Cody would be similar enough in personality, stand-offish. They wouldn't show a massive amount of emotion or talk to players in that sense. Derek Lyng would've been the more friendly type".
Lyng got his team off to a great start in 2022 winning the Leinster Under 20 Championship over Wexford by one point. Lyng, followed this with All Ireland success as Kilkenny won the Under 20 Championship with a win over Limerick for the first time since 2008.
