Outfielder Rudy Guillen was a top prospect whose career stalled at AA.
He signed by scout Victor Mata for the New York Yankees in 2000. He made his pro debut the next summer for the DSL Yankees, hitting a sound .281/.337/.498 with 11 homers in 62 games. He tied Tiago Magalhães for the Dominican Summer League lead in dingers. Coming stateside in 2002 with the GCL Yankees, he batted .306/.351/.397 with 38 runs in 59 games. Baseball America rated him as the #11 prospect in the Yankees chain and as the second-best Gulf Coast League prospect, behind one Hanley Ramírez.. In 2003, he put up a .260/.311/.414 line with 29 doubles, 13 home runs and 79 RBI for the Battle Creek Yankees. He joined Kennard Jones and Félix Pie as the Midwest League All-Star outfielders. He tied Sean Luellwitz for 8th in the MWL in RBI. Baseball America upgraded him to the Yanks' third-best prospect and listed him as #18 in the MWL (between John Baker and Jon Connolly).
Guillen began to stumble in 2004, in which he played for the Tampa Yankees (.264/.313/.339, 1 HR, 1 SB in 307 AB) and GCL Yankees (6 for 14). Baseball America dropped him to 12th on the Yankees prospect list, though they did list him as having the best outfield arm in their system. Rudy split 2005 between Tampa (.260/.305/.362 in 100 G) and the Trenton Thunder (.257/.289/.330). He was again rated as having the best outfield arm of a Yankees farmhand, but no longer was considered one of the system's top 25 prospects by Baseball America. In 2006, he continued to sputter with Tampa (.267/.311/.402, 10 HR, 14 SB in 85 G) and Trenton (.173/.195/.267, 27 K in 75 AB). Moving to the mound, he pitched 3 games for the 2007 GCL Yankees. In four innings, he allowed 4 hits, 3 walks and 3 runs, though he did strike out six.
