Baseliners

Baseliners are terms used in several domains to describe people or roles associated with a baseline. The term is formed from baseline with the agent noun suffix -er.

In sports, particularly tennis, baseliners are players who base their game on the baseline, preferring long rallies and heavy groundstrokes. They rely on consistency, width, and pace to control points and move opponents around the court. They contrast with serve-and-volley players and all-court specialists.

In geography and demography, Baseliners may informally refer to residents of Basel, Switzerland, though the standard English usage is Basel resident or Basler. The term Baseliners is uncommon in official contexts and may be considered informal or humorous.

In data analysis and clinical research, a baseliner is an individual or dataset that establishes a baseline for comparison. Baseliners define initial measurements, control conditions, or reference points from which change is assessed.

In software and project management, a baseliner can describe a person who defines baselines for scope, schedule, and cost or the act of establishing such baselines as part of baseline management.
