Tillman dealing with ankle soreness

BALTIMORE -- Chris Tillman threw one of his best outings against the Braves on Wednesday, but it may push back his next start.

The Orioles right-hander, who threw 8 2/3 innings of scoreless ball against Atlanta, rolled his left ankle on the final out of his performance when covering first base on a grounder to first. Tillman said the ankle was sore and had it wrapped when talking with reporters on Friday, adding that his situation is day to day.

"I don't think it's going to be anything serious," said Tillman, who is scheduled to start Monday. "If it's not my normal start day, maybe a day or two days, tops. It could very easily be Monday."

If Baltimore's Opening Day starter were to miss time, it would come when Tillman has been pitching as well as he has all season. He held the Braves to four hits Wednesday, and has allowed just one run over his last 23 2/3 innings.

After seeing his ERA rise to 6.22 following a rough outing June 21 against Toronto, Tillman has pitched to a 1.19 ERA in his last six games, picking up his fourth straight quality start Wednesday.
