The Twins have signed first round pick Alex Wimmers according to Kelsie Smith of The Pioneer Press (via Twitter). Joe Christensen of The Star Tribune tweets that he will receive a $1.33MM signing bonus, matching MLB's recommended bonus.
Minnesota selected Wimmers with the 21st overall pick back in June. The Ohio State righthander boasts the best changeup in the draft according to Baseball America, who also says that he throws his fastball at 90-92 and touches 94 mph. Smith says Wimmers will report to the Twins' Class-A Advanced affiliate in Fort Myers next week (Twitter link).
There are still 17 unsigned first round picks with ten days to go before the signing deadline.
