Roy Halladay and Mike Mussina will be portrayed on their Hall of Fame plaques wearing caps with no team logo on them, the Cooperstown shrine announced on Friday.
Halladay's career was divided between the Blue Jays and Phillies and Mussina's was split between the Orioles and Yankees. The two were elected to the Hall of Fame, along with Mariano Rivera and Edgar Martinez, on Tuesday by the Baseball Writers' Association of America.
Halladay, Mussina, Rivera, Martinez, Lee Smith and Harold Baines will be formally inducted into the Hall of Fame on July 21. As expected, the caps of the others' plaques will be Yankees for Rivera, Mariners for Martinez, Cubs for Smith and White Sox for Baines. An artist rendering of the Hall of Famer tops each plaque, and in many instances, a cap, on which a logo may or may not be featured.

Going without a logo is not unprecedented. Catfish Hunter, who pitched for the A's and Yankees, went without one when he was inducted in 1987, and Greg Maddux, whose 23 big league seasons were mostly divided between the Cubs and Braves, did the same in 2014.
Halladay, who was killed in a private plane crash in November 2017, played in 12 seasons for the Blue Jays, going 148-76, and four with the Phillies, with whom he pitched a perfect game and a no-hitter, including a no-hitter in the 2010 National League Division Series against the Reds.

"Roy was incredibly proud of his accomplishments with both the Blue Jays and the Phillies," Brandy Halladay, wife of the late pitcher, said in a release issued by the Hall of Fame. "We spent many great years in Toronto, where he established his career and became a Cy Young-winning pitcher. In Philadelphia, he reached the postseason, threw two no-hitters and won a second Cy Young Award. As a family, and with the blessing of the Hall of Fame, we feel confident that Roy would have come to the same conclusion, had he known it to be an option. Both franchises, and their fans, meant so much to him."

Mussina played for the Orioles for 10 seasons, going 147-81 while making five American League All-Star teams. He joined the Yankees as a free agent in 2001, going 123-72 and finishing his career as a 20-game winner in 2008.
"Both the Yankees and the Orioles were instrumental in my reaching Cooperstown," Mussina said. "I am proud to have played for these great organizations, in front of the tremendous fans in Baltimore and New York, and I am honored to have the opportunity to represent them both in the Hall of Fame."
