The National Baseball Hall of Fame is welcoming its newest members Pitchers John Smoltz, Pedro Martinez, Randy Johnson and infielder Craig Biggio  are being inducted at Cooperstown today.

Those four were elected as the 2015 Class by the Baseball Writers back in January. Their addition raises the number of Hall of Famers to 310.

Smoltz spent 20 of his 21 big league seasons with the Braves. The eight-time All-Star finished with 213 career wins and 154 saves, winning the 1996 NL Cy Young Award.

Martinez was a three-time Cy Young winner with 219 career victories for five different teams, but is best remembered for his seven seasons with the Red Sox. Martinez went 117-and-37 with Boston, helping the Red Sox win the 2004 World Series.

Johnson was a five-time National League Cy Young winner with 303 career wins for five different teams. He'll enter the Hall as a Diamondback, with whom he pitched eight seasons and won the 2001 World Series.

Biggio spent his entire 20-year career with the Astros, collecting 3,060 hits. He was a seven-time All-Star.

Hall of Fame weekend also featured the presentation of the Ford C. Frick Award to longtime broadcaster Dick Enberg on Saturday. (Metro Networks Inc.)
