61. Seth Maness
Unless you’re extremely partial to the strong month and a half that Alex Reyes put together last year, it’s pretty obvious that Seth Maness is the best No. 61 in Cardinals history. Maness, who wore the number for three seasons before switching to No. 43 for his final campaign with the Cardinals last year, was dominant for his first two big-league seasons. He posted a 2.32 ERA while getting the second-highest ground-ball rate in the majors (68.4%) over 66 appearances as a rookie, then posted a 2.91 ERA with a 1.10 WHIP during his sophomore season. He regressed a bit during his third season, but overall he was a net plus to the Cardinals’ bullpen while wearing 61.
