In February 1989, Scarpa, as Vince Young, would join World Championship Wrestling as part of a wave of fresh talent brought in under the new ownership of the company.

[4] Although he was not defeated in his tenure, Young abruptly left WCW following a March 23 match against Kendall Windham in Harrisonburg, VA after receiving a full-time position with the World Wrestling Federation.

Now a contracted performer with the WWF, Mark Young made his return on June 27, 1989, when he defeated The Brooklyn Brawler in a match that aired on International Wrestling Challenge.

Young was positioned as an opening match talent that was roughly parallel to Paul Roma, Steve Lombardi, Brady Boone, and Tim Horner.

Young entered into a losing streak and was winless against the Russian, but rebounded to put together a lengthy series of house show victories over Barry Horowitz.

Young also appeared on American television, teaming with Tim Horner and Jim Evans in tag-team matches against The Rougeau Brothers and The Brain Busters.

In November he was paired against Earthquake in the latter's initial run of house show matches, and gained his first victory on American television when he pinned Barry Horowitz on the December 4th edition of Prime Time Wrestling.

[5] Scarpa was less successful in 1990, and spent the first two months of the year on a losing streak before finally defeating Rico Fredrico in a house show match in West Palm Beach, FL on March 2.

Overbow appeared on American television for the first time in over a year when he faced Intercontinental Champion Roddy Piper on the February 15th edition of WWF Superstars.

His last match on record occurred on May 8 for the Mid-Eastern Wrestling Federation, teaming with Trent Young (no relation) in a loss to Joe Thunder and Johnny Blaze.
