No major surprise here. Left-hander Nate Robertson was designated for assignment on Wednesday following a rough outing the night before in which he gave up eight runs -- six in one inning -- in a loss to the Rockies. The Marlins are calling up reliever Jorge Sosa for now but will have to find a starter to replace Robertson in the rotation -- most likely Chris Volstad -- for Sunday's game against the Braves.
Robertson made 19 starts for the Marlins and went 6-8 with a 5.47 ERA -- the highest ERA in the N.L. among the 47 pitchers with at least 100 innings -- after the Marlins obtained him from Detroit before the season for minor-league reliever Jay Voss. The Tigers picked up all but $400,000 of the pitcher's $10 million salary.
In addition, the Marlins placed back-up catcher Brett Hayes on the 15-day disabled list with a left wrist injury and promoted catcher Brad Davis from Triple A New Orleans to take his place.
