Texas Rangers Prospects: Martin Perez and Juan Grullon

Martin Perez. LHP, 6' 0", 165 lbs, Born: April 4, 1991. Venezuelan Martin Perez has been the left-handed pitching prize of the 2007 Latin American free agent class. The Texas Rangers won the bidding for Perez and held him back until the unleashed him on the Northwest League in 2008 against players that were typically 3-4 years older than the then 17-year-old Perez. Walks were a small problem for Perez, and he was hit at a .274 clip, which isn't bad but isn't anything to brag about either. This resulted in a 3.65 ERA and a 1.52 WHIP. His strikeout rate was very good. He threw only 61.2 innings in 2008, so I don't expect him to jump past 100 this season. That said, he's already surpassed 25 innings in 2009. In that short sample, still against players much older than he is, Perez has lowered his walk rate (4.1 per 9 innings to 3.0), dramatically lowered his hit rate (9.6 per 9 innings to 5.7), and improved his already solid strikeout rate (7.7 per 9 innings to 10.5). Still only 18 years old, Perez has some serious projection left. [Video.] Juan Grullon. LHP, 6' 0", 185 lbs, Born: March 4, 1990. I dug around for information on this guy, and there simply isn't much to be had outside of his 2008 Dominican Summer League statistics which are pretty exciting. The Dominican lefty threw 48.0 innings and allowed only 37 hits while striking out 67 and walking 25, a few too many. Grullon did not allow a homerun. His efforts were good for a 6-1 record and a 2.44 ERA. We could see Grullon stateside this year with either Spokane or the AZL Rangers. He will be 19 years old all year. [Video.]
