PHILADELPHIA -- With Monday's injury to catcher Rod Barajas, the Pirates promoted Eric Fryer to back-up Michael McKenry for the time being. And with that decision, they had to clear a spot on the 40-man roster.
The odd-man out was left-handed pitcher Daniel Moskos, who was designated for assignment on Tuesday. Moskos was the fourth overall overall pick in the 2007 First-Year Player Draft.
Moskos, 26, was 1-1 with a 2.96 ERA in 31 relief appearances with the Pirates in 2011. He didn't make the club out of Spring Training this season and was 1-2 with a 3.86 ERA for Triple-A Indianapolis before he was designated for assignment.
"In Danny's case, I think that this was a hard decision to make, but at the same time it could be an appropriate time just to bring closure to it and move on," Pirates manager Clint Hurdle said on Wednesday. "He's given it everything he's got. He hasn't gotten probably the position in the organization that he'd like to be. Again, at the end of the day, I know he gave it everything he had. Sometimes things just don't work out. And they've got an opportunity to maybe work out for him somewhere else."
There is a chance he could return to the Pirates if no other club picks him up on waivers and the club decides to bring him back.
