Clay Rapada, American baseball player
Clayton Anthony Rapada (born March 9, 1981) is a Filipino American former professional baseball pitcher. He played in Major League Baseball (MLB) for the Chicago Cubs, Detroit Tigers, Texas Rangers, Seattle Mariners, New York Yankees, and Cleveland Indians. He is currently an assistant pitching coordinator for the San Francisco Giants organization.

He has appeared in 152 major league games but has pitched only 93 innings in that time, averaging about 2⁄3 of an inning per appearance. He does however hold a unique major league record. He has a career won loss record of 8–0 for a winning percentage of 1.000. This marks the most wins for a pitcher without ever being charged with a loss, presuming he doesn't resume his playing career and records a future loss at the major league level. He is not credited for his win percentage in the official baseball records because that required a minimum of 1,000 innings pitched.
