Philip Ramond Regan (born April 6, 1937) is an American former professional baseball pitcher, scout, and manager, who played in Major League Baseball (MLB) for the Detroit Tigers, Los Angeles Dodgers, Chicago Cubs, and Chicago White Sox; he also managed the Baltimore Orioles.

Entering the game already behind 3-0, he allowed just two hits in five innings of work, including a home run to Harmon Killebrew.

Relief pitcher Clem Labine walked Jim Gentile to drive in the winning run, and hand Regan his first career loss.

He earned a call up that September, and made two appearances, but it was while he was with Syracuse that Regan learned of interest in him from the Dodgers organization.

He responded by going 14-1 with a 1.62 ERA, 88 strikeouts in 116 innings pitched and a National League leading 21 saves to help the Dodgers capture the NL pennant by a game and a half over the San Francisco Giants.

[11] He appeared in two games of the 1966 World Series, allowing just one base runner via a walk, and retiring the other five he faced.

[17] Despite missing the first 14 games of the Cubs' schedule, Regan led all of Major League Baseball with 25 saves in 1968 on his way to capturing a second Sporting News Reliever of the Year Award.

He asked to be traded or released, and on June 2, Regan's contract was sold to the crosstown Chicago White Sox.

[23] Regan’s work at Grand Valley earned him a call from Seattle Mariners general manager Dan O'Brien Sr.[24] After spending the 1983 season as the Mariners' minor league pitching instructor and advance scout, Regan was promoted to major league pitching coach in 1984.

[25] His tenure in Seattle was interrupted by a two-game suspension in 1985 when he bumped umpire Derryl Cousins during a bench clearing brawl between the M's and California Angels on August 12.

In 1995, Regan received his only major league managerial position,[29] managing the Baltimore Orioles to a 71-73 record.
