Bob O'Brien

Robert Allen O'Brien (born April 23, 1949) is a former pitcher in Major League Baseball. He pitched in 14 games for the Los Angeles Dodgers during the 1971 season, including four starts and one shutout.

His Baseball Reference page shows that he played college ball at three different schools, Fresno City College, Texas A&M University and the University of Arizona and was drafted 4 times, by the Detroit Tigers in the 1968 January Draft, by the San Diego Padres in the 1968 June Draft and by the Dodgers in the 1969 January Draft and 1969 June Draft. This is incorrect--his SABR biographer's research reveals another lefty pitcher named Pat O’Brien who pitched for U. of Arizona in the mid-1960s and was drafted by the San Diego Padres in June 1968. A Robert P. O’Brien pitched in the Padres system in 1969 and 1970. The Pat and Robert entries appear to have been commingled with Bob O’Brien’s data.[1]

O'Brien was acquired along with Doyle Alexander, Sergio Robles and Royle Stillman by the Baltimore Orioles from the Dodgers for Frank Robinson and Pete Richert at the Winter Meetings on December 2, 1971.[2]
