Robertson designated for assignment
A day after his toughest outing of the season, Nate Robertson was designated for assignment.
Coming off a 10-0 loss to the Rockies on Tuesday night, Robertson allowed a season most eight runs, with seven earned over five innings.
Robertson was 6-8 with a 5.47 ERA in 19 games, including 18 starts. He threw 100 1/3 innings.
The Marlins acquired Robertson from the Tigers for lefty prospect Jay Voss towards the end of Spring Training.
The Marlins also placed catcher Brett Hayes on the 15-day disabled list with a left wrist contusion.
Right-hander Jorge Sosa and catcher Brad Davis each had their contracts selected from Triple-A New Orleans.
