Baseball America rated Mateo the Cubs' 11th best prospect headed into the 2007 season, but he fell on hard times in a hurry. He initially advanced steadily through the team's system and made a good transition from the bullpen to starting. After a strong showing in AA, he moved up to the majors in 2006 and pitched respectably considering his experience level. He generally had decent to good K rates and good control in the minors, but he began having shoulder problems in 2007 and missed much of the season. Considering his performance early in 2008, it seems likely the shoulder problems were still bothering him. The Cubs outrighted him off their 40-man roster and he opted for free agency. The Pirates signed him to a minor league contract a few days later. Mateo throws a fastball that ranges from 90-95 and was rated the best in the Southern League in 2006. According to BA, his other pitches are considered marginal, so his future, if he has any, figures to be in relief.

Mateo spent the remainder of 2008 in the bullpen at Altoona. After a slow start he was very effective. In July and August he had an ERA of 0.92, with 25 hits, 10 walks and 38 Ks in 39.1 IP. He's a flyball pitcher and RH batters hit only .170 against him for the season. By the latter part of the season he was pitching mostly in 2-3 inning stints, which may indicate the Pirates think of him as a middle reliever. He should be eligible for free agency after the season, so the Pirates will have to consider whether to put him on the 40-man roster.
