Rob Bell (35) -A Red in 2000-01. According to BaseballReference, the most similar pitcher to Rob is former Red Kevin Jarvis. That's not a compliment...
Don Zimmer (81) -Currently a special assistant in Tampa Bay, he still suits up for spring training, which makes him the last Brooklyn Dodger to still be in a major league uniform. He adds one to his jesey number every year to represent the number of years he's been in the game.
Mayo Smith -Reds manager preceding Fred Hutchinson. Best remembered for his gutsy move in Detroit in 1968, moving Mickey Stanley to shortstop for the World Series.
Chili Davis (52) -The first Jamaican to play in the majors. Ranks fifth among switch-hitters in career homers.
Mark Littell (59) -Ex-Cardinal and Royal reliever. After his playing days, he invented a new protective cup called the Nutty Buddy. The YouTube video he made to promote it features him taking a 90mph fastball in the relevant area, and is highly recommended.
Darrell Porter -Gutsy catcher who passed away in 2002. One of the first players to talk publicly about his substance abuse issues.
