Polonia is a fast singles hitter who stole a career-high 29 bases in 1987 for the A’s and scores a lot of runs. He switch-hit all through the minors, even in 1988, but only bats lefthanded in the majors. The Dominican is an erratic fielder, although he covers a lot of ground and has a quick release on his throws. The Yankees acquired him in the Rickey Henderson deal in mid-1989.
Polonia was sentenced to 60 days in prison in October 1989 after pleading no contest to a charge of having sex with a minor while in Milwaukee that August.
