Woodford was optioned to Triple-A Memphis on Sunday.
The 24-year-old surrendered seven runs over three innings during Saturday's start against the Twins, and he'll unsurprisingly exit the Cardinals' starting rotation with Jon Lester and J.A. Happ officially joining the team after being acquired at the trade deadline. Woodford started in his last three appearances for St. Louis but has primarily worked out of the bullpen this year and has a 5.08 ERA, 1.54 WHIP and 32:17 K:BB across 39 innings.
