Cubs starter Ryan Dempster was scratched from his team's Monday game against the Nationals with "intestinal issues" and manager Mike Quade seemed just as unsure about what was wrong with Dempster as when the right-hander would be able to make another start.
"It just seems like it's a product of his intestinal issues over the last couple of days," Quade told reporters, including Paul Sullivan of the Chicago Tribune. "I'm not smart enough to know that, but it's his whole [core] region."
Dempster was hospitalized on Saturday night, but released on Sunday. Dempster said he'd like to start again before the All-Star break, but Quade noted he'd like to see him throw off a mound before another start.
Casey Coleman started Monday's game for Dempster.
With Dempster missing Monday's start, all five of the starters in the Cubs' rotation at the beginning of the season have missed at least one start. Carlos Zamrbano (back) and Andrew Cashner (shoulder) are currently on the disabled list. Ramon Ortiz will start in Zambrano's place Tuesday against the Nationals.
The 34-year-old Dempster is 5-6 with a 4.99 ERA in 18 starts.For more baseball news, rumors and analysis, follow @cbssportsmlb on Twitter or subscribe to the RSS feed.
