Craig Breslow is pretty excited, and he should be.

The 35-year-old Boston Red Sox relief pitcher is making his first career start against the Baltimore Orioles on Saturday, and it will be his 523rd major league appearance. His outing marks the longest stretch of games played before a start since former Los Angeles Angels closer Troy Percival did it in 2007 after 639 games.

When Breslow takes the mound, he’ll be the oldest Red Sox pitcher to make his first career start since Scott Atchison and the oldest Major League Baseball player overall since 1990.

NESN’s Guerin Austin sat down with Breslow on “Red Sox First Pitch” before the historic start. Check it out in the video above.
