In between those signings, the Cubs also inked two other notable selections in 21st round pick Logan Watkins, who bypassed a college scholarship to Wichita State, and 24th-round pick David Cales, a right-hander from St. Xavier (Ill.).
Shortly after the subsequent signings of Cashner and Shafer, both highly touted college arms, Cubs Scouting Director Tim Wilken told InsideTheIvy.com that the club had "pretty much signed everybody we wanted to."
On Friday, Wilken said via text message that the club had signed no additional draft picks by the midnight deadline. That left RHP Alex Wilson, a 10th-round selection from Texas A&M, as the only player drafted by Chicago in the first 26 rounds not to sign.
Wilson, 21, missed all of last season recovering from Tommy John surgery and was 0-1 with a 4.60 ERA in 29 1/3 innings with the Falmouth Commodores of the Cape Cod League this summer.
