The Yankees and closer Mariano Rivera agreed on a contract extension of $21 million over 2 years. The 34 year old pitcher signed with the Yankees in 1990 and is in the final year of his contract, which pays him $8.89 million this season. There is an optional 3rd year worth $10.5 million.

Over his nine year career, Rivera has 283 saves, a career 2.49 ERA, and a 1.07 career WHIP. Rivera also has 30 career postseason saves, two times the amount of Hall of Famer Dennis Eckersley, the next closest pitcher. Rivera is known for his cut fast ball, with late movement into left-handed batters.

Gothamist Baseball 101: Typically, left-handed batters fare better against right-handed pitchers because they can see the ball better and have more time to react to the ball before it comes to the plate. The same goes for right-handed batters and left-handed pitchers. Rivera is a right-handed pitcher, but his cut fast ball is so good that some switch hitters (batters than can hit from both sides of the plate) bat righty against him, which is against the norm.
