He was signed by the Houston Astros in 1991 and played several seasons in Latin America. He was 0-1 with a 8.53 ERA for the '91 DSL Astros. In 1993, he had a 3-2, 2.21 record for that club, finishing 10th in the Dominican Summer League in ERA (though Baseball America spelled his name Newman Lois). He came to the United States in 1994, going 6-1 with a 1.86 ERA in 13 starts for the GCL Astros that year. On August 19th of that season, he threw a seven-inning no-hitter against the GCL Cubs, allowing only one runner, Brad Chambers, on a walk. He was 7th in the Gulf Coast League in ERA, leading his team.
He split the following summer between the Auburn Astros, for whom he was 1-1 with a 2.63 ERA in 3 starts, and the Kissimmee Cobras, for whom he went 0-8 with a 5.56 ERA in 13 outings. He spent most of the next two seasons with the Quad Cities River Bandits, splitting time between the rotation and the bullpen before pitching for Kissimmee again at the end of the 1997 campaign. In 1996, he had a 8-6, 4.93 record for Quad Cities, followed by 2-5, 4.87 in 1997. For Kissimee in '97, he was 1-1 with a 3.82 ERA. He appeared in a dozen games for the Stockton Ports in the Milwaukee Brewers organization in 1998 (7.84, 19 BB in 20 2/3 iP) before a rotator cuff injury ended his career.
