The Mets signed RHP Lino Urdaneta during the July, 2005 from Cancun of the Mexican League. 

His only experience in the major leagues came during 2004 with the Tigers, when he allowed six runs on five hits and walked one and was removed before retiring a batter.

In the New York Times, Ben Shpigel profiles Urdaneta, and talks with the pitcher about returning to baseball after his one-inning disaster in Detroit.

As Shpigel notes, Urdaneta is one of 19 pitchers who have allowed an earned run without retiring a batter, in other words he has an ERA of infinity.

…i’ve been told he throws in the 90– to 95–mph range, with a fastball that has little movement…occasionally he’ll throw a weak slider…he has the make-up of a closer, but has been plagued with elbow trouble on and off for a few years
