Right-hander Marcus Hatley's contract was purchased from Triple-A Memphis. To make room on the 40-man roster, reliever Jordan Walden was transferred from the 15-day disabled list to the 60-day DL.
The 35-year-old Belisle is 1-1 with a 3.00 ERA in 30 games with 24 strikeouts in 30 innings.
This is the first call-up for the 27-year-old Hatley, who joined the team for a two-game interleague series against the White Sox beginning Tuesday night. Hatley was 4-2 with a 1.69 ERA in 27 games for Memphis.
The Cardinals signed Hatley as a minor league free agent last November after he'd spent nine years in the Cubs' organization.
