Chicago Cubs right-hander Carlos Silva (10-4, 3.76 ERA), who is experiencing a stunning resurgence after two horrible seasons in Seattle, left Sunday’s game against the Colorado Rockies in the first inning with an abnormal heart rate, according to the Associated Press. He will remain in a Denver hospital overnight for observation.
Alan Trammell, managing the Cubs in place of Lou Piniella, who left the team to attend his uncle’s funeral, said he was unaware of any history of heart problems for Silva.
A Cubs trainer went to the mound after Silva walked the second batter he faced, Jonathan Herrera. Silva stayed in and allowed a single to Carlos Gonzalez and a ground-rule RBI double to Troy Tulowitzki.
Trammell and the trainer went back to the mound, and Silva was replaced by left-hander James Russell.
“Whether it is at the altitude, I don’t know,” Trammell said. “We saw something after Herrera’s at-bat when he backed off the mound. We thought something was wrong.”
The Chicago Tribune reported that Silva’s heart rate returned to normal on the way to the hospital, and that he was resting comfortably.
