CHICAGO -- Right-hander Dallas Beeler, who has been pitching this season at Triple-A Iowa, will be added to the Cubs' roster Saturday to start the first game of a doubleheader against the Nationals.
Beeler, who turned 25 on June 12, is 5-3 with a 4.03 ERA in 10 starts at Iowa this season, striking out 43 while walking 15 over 60 1/3 innings.
"All the guys showed very well this spring," Cubs manager Rick Renteria said Wednesday. "I think he's a kid who everybody is looking forward to having an opportunity to show what he can do."
Beeler was a 41st-round pick in the 2010 First-Year Player Draft. In his last start Monday against Albuquerque, he gave up three runs on four hits and two walks over six innings.
"Having the doubleheader, you have the opportunity to have another pitcher," Renteria said. "We just felt it behooved us to bring someone who has been starting right now. It doesn't hurt us to have Beeler come up and be seen and put forth his efforts for us at this time."
Teams are allowed to add a 26th player for day-night doubleheaders without having to make an additional roster move.
