Stephen Strasburg might be pushing closer to that management-imposed innings limit -- whatever the number might be in the mind of the brass. Washington's ace brushed off questions on the topic, and so did manager Davey Johnson.

Strasburg capped Washington's longest road trip of the season by winning his third straight start in a 6-4 victory over the San Francisco Giants on Wednesday.
