The Orioles weren't the only team fiddling with their roster today. The White Sox designated right-handed reliever Mike MacDougal for assignment and recalled right-hander Jack Egbert from Triple-A Charlotte.
Obviously, the Orioles aren't the only team with some bullpen depth issues, since Egbert had a 6.43 ERA (five earned runs in seven innings) in five minor league appearances. MacDougal, who broke through in 2003 with 27 saves for the Kansas City Royals, but has struggled with injuries and ineffectiveness since the White Sox acquired him in a midseason deal in 2006.
Slightly interesting side note: MacDougal was drafted twice by the Orioles (1996 and 1998), but did not sign with them either time.
