Guillermo Moscoso grabbed headlines in 2007 when he tossed a perfect game for the Oneonta Tigers. What else does Moscoso have in store for his future?

Background
Moscoso was signed by the Tigers' Ramon Pena as an amateur free agent in November 2002 and spent the following two seasons pitching for their Dominican Summer League affiliate. In two seasons with the DSL club, Moscoso compiled an 8-3 record with 146 strikeouts in 129 innings pitched. His 90 innings of work in his second DSL season ranked fourth among league participants, and his three complete games placed him in a tie for second.

At age twenty-one Guillermo came stateside and debuted with the Oneonta Tigers where he turned in a solid performance through eleven appearances (ten starts). His 2-2 record belied his performance as he managed a 4:1 strikeout to walk ratio and 1.27 WHIP in 47-1/3 innings. Some minor injuries toward the end of the 2005 season set back his development, forcing a demotion to the Gulf Coast League in 2006. As a 22-year old working in the relatively inexperienced GCL, Moscoso turned in an outstanding performance working primarily in relief.

The 2007 season served as Moscoso's awakening; as he tied for second in the league in wins (8), tied for first in both complete games (2) and shutouts (1), and ranked fourth in the league in both innings (79-2/3) and earned run average (2.37). He was named the MiLB.com Pitcher of the Week for July 9, 2007 on the heels of his perfect game against the Batavia Muckdogs. His perfect game also earned him MiLB.com's Class A Short-Season Single-Game Performance of the Year Award.

Scouting Report
Despite some injuries in his past, Moscoso has managed to continue developing his arsenal and appears poised to maintain that trend. Armed with a low-90s fastball that can reach 94 on occasion, Moscoso challenges both sides of the plate with regularity and can spot the ball with above-average ability. His fastball has limited movement and he doesn't work low enough to keep the ball on the ground routinely. He has pitched in some pretty favorable environments to date, and may have trouble keeping the ball in the yard against more advanced competition.

Guillermo has messed with several different off-speed pitches in recent seasons, seemingly settling on a slurvy breaking ball and change-up. Having played with a splitter in the past to some degree of success, there is a chance the pitch could be resurrected down the road. His curveball has made strides in terms of consistency, but it is quality is not there. The pitch lacks dominating bite, often floating through the zone. His change-up has shown promise since coming back from injury, but he still must work to maintain his arm speed and deception.

Moscoso's most impressive trait has been his ability to attack hitters and throw strikes. He carries supreme confidence in his ability when on the mound and he does not know how to back down from hitters. This type of approach may play better in the bullpen long term, as the shorter stints could also allow him to gain some added velocity on his fastball, and may mask some of the deficiencies in his secondary offerings.

Health Record
Moscoso has battled some relatively minor arm injuries throughout his career, most recently toward the end of the 2005 season, but none of them appear to be long term concerns. With a likely jump to full-season ball for the 2008 season, his workload will need to be watched as he has yet to throw more than 90 innings in a given season.

The Future
Guillermo will enter minor league spring training penciled in with a full-season pitching staff; whether that staff is in West Michigan or Lakeland will be the topic of debate. Given his relatively advanced age, Moscoso could prompt the organization to push him to Lakeland with a strong spring; a move that would place him in the most favorable offensive environment of his career, and likely provide a stiff challenge to start the season.

While Moscoso has continued to work in the rotation, his future role likely lies in the bullpen where his attacking, strike throwing ways will serve him well in a variety of relief roles. With a strong cadre of starting pitchers moving through the Class-A ranks, Moscoso may be pushed to the ‘pen as soon as this season.
