Arrieta celebrates birthday with A-list Cubs roster

When you're the Cy Young of the National League, your birthday party is going to be well attended.

On his 30th birthday Sunday, Chicago Cubs right-hander Jake Arrieta was surprised by his wife, Brittany, and a slew of attendees, including some of his teammates.

Arrieta and the Cubs are one of the favorites to win the World Series in 2016 after adding Jason Heyward, Ben Zobrist, and John Lackey to a roster responsible for a 97-65 last season.
