Nottinghamshire batsman Karl Turner hopes to do enough in the current Championship game with Sussex to earn a deal at Trent Bridge for next season.
Turner, 23, joined in July after being released by Durham and has played the final five County games this term.
He averaged 17.28 before scoring 64 and 42 in against Sussex.
And Turner told BBC Radio Nottingham he knew he had to impress in the season finale: "I've had a few starts but needed to get a score under my belt."
Turner scored two centuries in his first two appearances for Notts Seconds in July.
But he added: "I've shown in the second team games that I can score runs and play but it's a different kettle of fish in the first team trying to prove that because of the step up."
