The Cardinals have designated Francisco Samuel for assignment, reports Brian Walton of FOX Sports Midwest (on Twitter). The move frees up a 40-man roster spot for Eduardo Sanchez, who was activated off the 60-day DL.
Samuel, 24, pitched to a 12.17 ERA with 17 strikeouts and 16 walks in 14 innings between three minor league levels this year. He topped out at Double-A after pitching at Triple-A last season. Samuel has battled lat and shoulder troubles this year, hence the low innings total.
