Answer: Shane Reynolds
Shane Reynolds began his MLB career in 1992 at the age of 24 with the Houston Astros. He spent the majority of his career with the Astros and only one season with the Braves.
Over his 13-season career, Reynolds posted a 114-96 W/L record with a 3.95 ERA in 305 games. Of those 305 games, he was the starting pitcher for 278 of them.
Reynolds is most certainly one of those obscure Atlanta Braves players that fans forget about.
