COOPERSTOWN, N.Y. -- The Hall of Fame made some small adjustments to its veterans committee system to limit people with relatively little support from repeatedly remaining on future ballots, a decision that could make it harder to gain entry to Cooperstown for steroids-tainted stars such as Barry Bonds and Roger Clemens.

Any candidate on the eight-person ballot who receives fewer than five votes from the 16-member panel will not be eligible for that committee's ballot during the next three-year cycle, the hall said Wednesday. A candidate who is dropped, later reappears on a ballot and again receives fewer than five votes would be barred from future ballot appearances.

Bonds, Clemens, Rafael Palmeiro and Albert Belle each received fewer than four votes in December 2022, when Fred McGriff was a unanimous pick. Bonds and Clemens were on a hall ballot for the first time since their 10th and final appearances on the Baseball Writers' Association of America ballot. The rules change could limit reappraisals of their candidacies.

In addition, the historical overview committee appointed by the BBWAA that selects the ballot candidates must also be approved by the hall's board of directors. The hall said the decisions were made by its board during a Feb. 26 meeting in Orlando, Florida.

In 2022, the hall restructured its veterans committees for the third time in 12 years, setting up panels to consider the contemporary era from 1980 on, as well as the classic era. The contemporary baseball era holds separate ballots for players and another for managers, executives and umpires.

Each committee meets every three years: contemporary players from 1980 on will be considered this December; managers, executives and umpires from 1980 on in December 2026; and pre-1980 candidates in December 2027.

Dave Parker and Dick Allen were elected last December and manager Jim Leyland in December 2023.
