(BaseballStL) -- The St. Louis Cardinals agreed to send left-handed reliever Marc Rzepczynski to the Cleveland Indians for a low-level minor league prospect on Tuesday.
In exchange, the Cardinals receive shortstop Juan Herrera. The 20-year-old was batting .275 in 39 games this season for the Mahoning Valley Scrappers in the New York-Pennsylvania League. He will be assigned to the Class-A affiliate State College Spikes.
Hours before the trade announcement, Rzepczynski was sent to Triple-A Memphis after allowing two runs in 1.1 innings pitched in a 9-2 loss to the Pittsburgh Pirates the night before. The trade ends a curious situation similar to that of Mitchell Boggs, who was sent to the Colorado Rockies earlier this month.
Rzepczynski was sent to the minors after posting a 7.88 ERA in nine games pitched in April. He was promoted to the major league club on July 25 and appeared in two games before the trade.
The trade of Rzepczysnki marks the final piece of the Colby Rasmus trade in 2011 gone from the organization. The other pieces include: Octavio Dotel, Edwin Jackson and Corey Patterson.
Derrick Goold of the St. Louis Post-Dispatch was the first to report the trade.
