The outing was Halladay\'s shortest since the right-hander exited after four innings in Chicago against the Cubs on July 18 of last season. Halladay left that game due to heat exhaustion. The two-time Cy Young Award winner has struggled this season, especially this month. Halladay has a 6.11 ERA in May with 24 earned runs over 35 1/3 innings in six starts. Halladay was 3-2 with a 1.95 ERA in five starts in April.
