Ethan Mildren and Elvin Soto were taken in the MLB Draft earlier this year and both have opted to sign and start their professional careers. Mildren and Soto are both shown as signed on the rosters of their new teams - the Minnesota Twins and Arizona Diamondbacks respectively.
The third Pitt player taken, pitcher Matt Wotherspoon, still wasn't signed as of Saturday.
Sucks to lose both of those first two guys and the same would hold true for Wotherspoon if he leaves as well, but there's no way you could blame them. And it's even better that all three contributed largely to Pitt's success. It's a positive to have more guys in farm systems from the Panthers and hopefully it's a sign of things to come.
