Robinson played in seven games for San Diego during the 1971 season, all off the bench as a pinch-hitter, going 0-6 at the plate with a walk.
The previous season he had his first taste of the big leagues when he appeared in 15 games for the Padres, batting a very nice .316 with 12 hits over 38 at-bats with a couple of homers and six runs batted in.
That would be it for him in the Majors however, and he would finish his brief career with a .273 average, with 12 hits in 44 at-bats over 22 games.
Oddly, I don’t know what happened, but he never appeared in a game, Major or Minor, ever again, with his pro career lasting three years total.
