On June 22, 1989 Craig Biggio got hit by a major league pitch for the first time, but he also became the first player taken in the 1987 amateur draft to record a plunk. He beat 4 other '87 draft picks who were also hit for the first time in 1989 - Bill Spiers, Steve Finley, Ken Griffey Jr. and Albert Belle. When Biggio got hit, he ended a long since someone had been the first player plunked from their draft, because the 1986 drafts first plunk came just 3 months after the draft. Bo Jackson was drafted on June 2, 1986 and was hit by his first pitch on September 14, 1986. The only other player since 1980 to be drafted and plunked in the same year is Rickie Weeks who was drafted in June 2003 and plunked on September 20th that year.
