The Marlins placed outfielder Christian Yelich on the 15-day disabled list with a lower back strain. Yelich has missed the last three games, and the transaction is retroactive to April 20.
Yelich is hitting .200 with no home runs and four RBI this season.
To replace Yelich on the roster, the Marlins called up first baseman Justin Bour from Triple-A New Orleans. Bour was hitting .275 for New Orleans this season with one home run and five RBI.
Bour played in 39 games for the Marlins last season, hitting .284 with a homer and 11 RBI.
