The New York Yankees announced today that they have signed right-handed closer Mariano Rivera, the American League's all-time saves leader, to a two-year contract. Rivera, 41, owns 559 career saves, the most in franchise history and the second-most all-time behind Trevor Hoffman (601). His 394 saves over the last 10 seasons are the most in the Majors, while his 978 career appearances are the most-ever by a Yankees pitcher and place him in 17th place on Baseball's all-time list.
Since earned runs became an official statistic in the National League in 1912 and the American League in 1913, Rivera's 2.23 career ERA is the second-lowest all time among pitchers with at least 1,000.0 innings pitched, according to the Elias Sports Bureau, trailing only Eddie Cicotte's 2.20 career ERA over the span. The Panama native was originally signed by the Yankees as a non-drafted free agent on February 17, 1990, and is currently the longest-tenured Yankee (15 yrs, 105 days).
