The Twins have voided the $3 million contract of 16-year-old Dominican shortstop Jelfry Marte due to an issue the team discovered during his physical. The Twins' concern, according to multiple sources, related to Marte's vision. Marte is now a free agent and worked out yesterday for clubs in Orlando along with a group of 2018 and 2019 players in the Dominican Prospect League. A switch-hitter, Marte was Baseball America's No. 13 international prospect in the 2017 class. Prior to signing, Marte, who is 5-foot-11, 170 pounds, stood out for his athleticism, speed and defensive actions. BA subscribers can read a full scouting report on Marte here. With Marte's contract voided, the Twins have an extra $3 million available in their bonus pool for the 2017-18 signing period, which ends on June 15, 2018. Japanese two-way star Shohei Ohtani is the biggest name on the verge of becoming eligible to sign, while Cuban center fielder Julio Pablo Martinez is also likely to be declared a free agent during the current signing period. It's also possible Marte could still sign with the Twins for a smaller bonus.
