Daniel Merida's Rolex Paris Masters run ended on Wednesday, when Tommy Paul beat him decisively to move into the last 16. Earlier in the week, Merida had played Sebastian Baez in a match that earned him the meeting with Paul.
Paul controlled the match from start to finish and gave Merida few chances to get into it.
The win over Baez on Monday gave Merida a meeting with a seeded opponent on one of the tour's big indoor stages.
Reaching the second round in Paris is still a solid week for Merida to build on.
