Manager Giles White is refusing to get carried away by Hamshire's impressive start to this season's FL t20.
The County have won all five of their games in the competition to sit top of the South Group.
"We've had a good start but it's early days, there's still so much cricket to be played and any side can beat each other," he told BBC Radio Solent.
"The key is to keep working hard and put in good performances."
Hampshire were denied the chance to extend their winning run to six games on Sunday when their match at Somerset was abandoned due to rain.
The county are next in action against Glamorgan on Friday but White admits he was frustrated by the decision to cancel Sunday's match.
"We are disappointed the game has been cancelled, we are in good form and want to carry on that momentum but the rain defeated us," he said.
"But we'll have a good break now and come back on Friday in the game against Glamorgan."
Meanwhile, Hampshire overseas player Shahid Afridi's disciplinary hearing at the Pakistan Cricket Board (PCB) has been postponed until 16 June.
Afridi is currently unavailable for the County after his contract was suspended following his criticism of the PCB.
