BOSTON (CBS) — Not that there was any doubt, but Ken Griffey Jr. is officially a Hall of Famer.

Griffey headlines this year’s Hall of Fame class, after garnering support from 99.3 percent of the 440 votes cast by BBWAA members. It was Griffey’s first year of eligibility. With that vote, Griffey earned the highest voting percentage of any player in history, surpassing Tom Seaver’s 98.84 percent.

Mike Piazza, in his fourth year on the ballot, also was elected to the Hall of Fame. Last year, Piazza received 69.9 percent of the votes but surpassed the needed 75 percent mark with 83 percent this year.

The closest runner-ups were Jeff Bagwell and Tim Raines, who garnered 71.6 percent and 69.8 percent, respectively.

Griffey played for the Mariners, Reds and White Sox in his 22-year career. In total, he batted .284 with a .907 OPS and hit 630 home runs. He was named to 13 All-Star teams, he won 10 Gold Glove Awards and he was the 1997 AL MVP. He hit 56 home runs in the 1997 and the ’98 seasons, following them up with a 48-homer campaign in 1999.

Piazza, in his fourth year on the ballot, spent his 16-year career with the Mets, Dodgers, A’s, Padres and Marlins. The catcher batted .308 with a .922 OPS and 427 home runs.
