Juan Morillo was signed by scout Rolando Fernandez for the Colorado Rockies in April 2001. He made his pro debut with the DSL Rockies in the Dominican Summer League that same year (2-4, 6.81) and in 2002 (1-5, 4.75). In 2003, he joined the Casper Rockies of the Pioneer League, where he went 1-6 with a 5.91 ERA. The next season, 2004, he put up better numbers for the Tri-City Dust Devils, going 3-2 with a 2.98 ERA, 4th in the Northwest League. He also struck out 73 batters and was an All-Star. Morillo began 2005 with the Asheville Tourists, where he went 1-3 with a 4.54 ERA and struck out 43 in 33 2/3 innings before being promoted to the Modesto Nuts, where he was 6-5 with a 4.41 ERA. He spent most of 2006 with the Tulsa Drillers, going 12-8 with a 4.62 ERA and 132 strikeouts in 27 starts. Late in the season, he made his big league debut with the Rockies, starting a game and giving up 7 earned runs in 4 innings.
Morillo signed with the Rakuten Golden Eagles for 2010. He debuted on March 27th with one walk in two-thirds of an inning. Injuries limited him to 7 games (9 K, 5 BB, 3 H, 2 R in 6 2/3 IP) while he peaked at 99 mph on the radar gun. He left the team the next year, citing stress related to the earthquake and tsunami that ravaged the area around Rakuten's stadium.
