The late Phillies ace Roy Halladay headlines a group of 20 first-time candidates on the 35-player writers’ ballot for the National Baseball Hall of Fame.

Halladay spent the last four of his 16 major-league seasons with the Phillies.

The late righthander was a two-time Cy Young Award winner and had a reputation as a workhorse.

He racked up three 20-win seasons, eight years with at least 200 innings, and five seasons with 200 or more strikeouts.

He pitched 67 complete games, more than any pitcher since 1998, one perfect game and the second no-hitter in postseason history in 2010 for the Phillies.

Of the first-time candidates, Halladay and legendary New York Yankees closer Mariano Rivera have the best chance to gain the 75 percent of the vote needed for election by the Baseball Writers’ Association of America.
