Gloucestershire bowler David Payne says Ian Cockbain deserves a place in the team for the Division Two match against Derbyshire, which starts on Wednesday.
Cockbain has scored 79, 48, 51 and 59 in his last four one-day innings.
Gloucestershire have named a squad of 12 including Cockbain and James Fuller, but the final choice will depend on whether they play an extra batsman.
"He's in unbelievable form - it would be perfect if it transferred into this game," Payne told BBC Gloucestershire.
"It looks like it's going to be a tough one at Derby, it doesn't look like it's going to be a great batter's pitch.
"We need someone who's going to do a job for us, it may be one big score that could play a crucial part in this game."
Payne himself is relishing facing Derbyshire again, after his impressive figures on the opening day of the season in April.
Gloucestershire are now pushing for promotion in Division Two and currently sit third behind Northants and Middlesex.
"It was a good game for me," added Payne. "I'm looking forward to it again - we've got to keep winning and keep our hopes for promotion alive."
