Panic Mode?

Is this a desperation move?:

Right-hander Radhames Liz will make his major league debut Saturday, starting for the Baltimore Orioles against the Minnesota Twins.

It will be the first time in his three-year professional career that Liz will pitch above the Class AA level. The 24-year-old is 11-4 with a 3.22 ERA this season with Double-A Bowie. He leads the Eastern League with 161 strikeouts (in 137 innings) and pitched a no-hitter on June 1 against Harrisburg.

I know that it's hard to call a move to call up a 24-year old rookie from AA a desperation move for a team that has lost four in a row and is 14 games out of the Wild Card. And it's not like there were any alternatives on the 40-man roster. But it seems that purchasing the contract of a starter from Norfolk such as 35-year old Tim Kester or 27-year old Aussie Craig Anderson may have made more short-term sense than the still raw Liz. Particularly given how late-season, emergency starters such as Hayden Penn, Brian Sackinsky, John O'Donoghue, etc. have worked out over the years....
