Leg-spinner James Muirhead has committed to Victoria for the next four seasons by signing a long-term deal to stay in his home state.

The 20-year-old made his first-class debut for Victoria last summer, but has not played a Sheffield Shield match this season.

However, he is expected to feature prominently in the four-day team when the Shield restarts next week.

"I feel like Victoria is the best environment for me to develop my cricket," Muirhead told ESPN Cricinfo.

"I was born in Melbourne, I live in Melbourne and now I can just focus on playing my cricket in Melbourne. We've got a great set-up, with the best coaches, so I'm very happy."

Muirhead played in all three of Australia's T20 wins over England earlier this year, taking four wickets in the process.
