Why we like him: Jim Kaat pitched for 25 seasons and until he was 44. Obviously, the guy managed to stack up some impressive numbers over the course of his career. He was a 3-time All Star and a reliable workhorse for the Minnesota Twins in the '60s and '70s. He won 20+ ballgames three times during his career and finished with a 283-237 career record.
Many might even know Kaat better for his work on the microphone instead of on the mound. He's been in broadcasting since his retirement in 1983. He's called games for YES and NESN, and he's currently working for MLB Network calling games at the ripe old age of 74.
Ladies and gentlemen, Jim Kaat, ballplayer.
