The Marlins claimed pitcher Asher Wojciechowski off waivers from the Astros and optioned him to Triple-A New Orleans, the club announced.
Wojciechowski, 27, was considered one of the top prospects in Houston's minor league system. The same was true when he was pitching for the Blue Jays' minor league affiliates.
Houston acquired Wojciechowski in the 10-player deal that sent J.A. Happ to Toronto and Francisco Cordero to the Astros. He was the 41st overall pick in the 2010 draft.
Wojciechowski made his major league debut last season with Houston, pitching to a 7.16 ERA and 4.05 FIP over 16.1 innings. His line was not that extreme in Triple-A in 2015, though.
Over 115.1 innings, he pitched to a 4.92 ERA and 4.78 FIP.
Wojciechowski's best minor league season came in 2013, when he pitched to a 3.56 ERA and 4.00 FIP over 134.0 innings in Triple-A.
In the corresponding roster move, the Marlins designated lefty Tim Berry for assignment. Berry had success in Double-A in 2014 but struggled throughout the 2015 campaign.
