CHICAGO -- Hayden Simpson, the Cubs' No. 1 Draft pick, will not play baseball this summer because he's battling mononucleosis, according to scouting director Tim Wilken.
Wilken was in Boise on Monday with the Class A Short-Season team, where Simpson would have reported by this time. The 16th overall selection out of Southern Arkansas, Simpson went 13-1 with a 1.81 ERA in 99 1/3 innings over his junior season.
The Cubs planned on having Simpson report to Mesa, Ariz., after he signed on June 19 and then report to Boise. The day he signed, Simpson had a side session at Wrigley Field with Cubs pitching coach Larry Rothschild.
"Maybe this is a blessing in disguise," Wilken said. "Not for Boise and not for the selfish Tim Wilken, who wants to see him in a game."
