Out of bizarre curiosity, I looked up the oldest players to wear a Toronto Blue Jays uniform. Dave Parker (40 years, 3 months, 7 days) ... Jason Grilli (40 years, 4 months, 22 days) ... Dave Winfield (40 years, 6 months, 4 days) ... Dave Stieb (40 years, 10 months, 26 days) ... R.A. Dickey (41 years, 5 months, 6 days) More items...
