In the latest USA Today/Gallup poll, 57 percent of fans questioned said they thought Clemens wasn't telling the truth when he denied taking steroids or human growth hormone in testimony before a congressional committee, USA Today reported Wednesday.
The telephone poll of 456 fans was conducted Thursday-Sunday by the Gallup organization.
In addition to questions about Clemens' testimony, respondents were asked whether Clemens or Pete Rose, who admitted betting on baseball games, should be elected to the Baseball Hall of Fame. Sixty-six percent of those polled said Rose should be honored while 62 percent thought Clemens was deserving.
A slight majority of respondents, 55 percent, said baseball Commissioner Bug Selig shouldn't punish players for the use of performance-enhancing drugs. A spokesman for the commissioner has said Selig will take each case individually and will make his decision public at the appropriate time.
Clemens arrived in Florida Tuesday so he can pitch to the Houston Astros minor leaguers.
