Strzelecki declined his outright assignment to Triple-A Memphis and elected free agency Saturday, John Denton of Roundtable.io reports.
St. Louis reinstated Strzelecki from the injured list Wednesday after he completed his recovery from right forearm extensor inflammation, and he was subsequently designated for assignment. The 31-year-old journeyman made eight appearances out of the Cardinals' bullpen this season, allowing nine runs with an 8:6 K:BB in 14 innings.
