Young Glamorgan Pathway players Jack Murphy, Kieran Bull, Connor Brown and Owen Morgan have extended their contracts with the Welsh county.
Murphy, Bull and Brown have signed two-year deals with the club, while Morgan has penned a new one-year contract.
Batsmen Brown and Murphy and off-spinner Bull, have all put in good performances for the first team this year with Brown striking 98 against Essex Eagles in the Royal London One-Day Cup, while Murphy has scored over 500 runs in the Specsavers County Championship, including a First-Class career-best against Kent.
After impressive displays in the Glamorgan second team, Bull has forced his way back into the first eleven towards the end of the year and took 3/36 in the second innings against Derbyshire on his return to the side.
Meanwhile, Swansea-born all-rounder Morgan burst on to the scene in 2016, grabbing the headlines with a match-winning 103 not out against Worcestershire in just his fourth first-class match.
Director of Cricket, Hugh Morris, said: “I am delighted that Jack, Connor, Kieran and Owen have signed new contracts and committed their futures to the Club.
“It is part of our strategy to develop young local players and bring them through into the first team and all four players have come through our Pathway system and put in some encouraging displays for Glamorgan during their short careers.
“Jack is developing his game at the top of Glamorgan’s order in his first full season in the first team and Connor showed his talent against a strong Essex Eagles side.
“Kieran has had to wait a long time for his opportunity but has grabbed it with some impressive displays and Owen has shown his potential in the past with a fantastic match-winning innings.
“With these young players coming through into the first team, as well as the likes of Kiran Carlson and David Lloyd we are looking to build for the future and develop a side Wales can be proud of.”
