Halladay exits in fifth inning

CHICAGO -- Surely, it is a sight that until Monday was contained solely in the nightmares of Phillies fans: Roy Halladay being escorted off the mound with a team trainer.

With a 1-1 count to Aramis Ramirez in the fifth inning, Halladay stepped off and Carlos Ruiz sensed something was wrong. So, too, did Rich Dubee, who emerged from the dugout. Before the pitching coach arrived, Halladay already had his hands on his knees.

He looked absolutely exhausted after pitching four innings. The team only offered this update: Halladay left the game due to the heat. (No word if he'll be joining LeBron in Miami.)

Halladay ditched his usual 3/4-sleeve undershirt after a 31-pitch third inning, when he also required time for a breath behind the mound. The game-time temperature was 91 degrees with stifling humidity.

After Dubee came to the mound, head athletic trainer Scott Sheridan followed. Soon after, Halladay was voluntarily walking off the field.

It represented Halladay's shortest outing as a Phillie. It also snapped a streak of 63 consecutive road starts in which Halladay threw at least six innings. That was the longest since Hall of Famer Walter Johnson did it in 82 straight starts from 1911-15.

Andrew Carpenter relieved Halladay.
