"Obviously, we'll see how tomorrow goes, but I don't see any reason to think it wouldn't be fine," said Maholm.
Because of the truncated exhibition schedule this year, injured players have less time to recover from minor Spring Training injuries and still be on the March 16 flight to Australia for the season-opening series against Arizona.
Maholm was signed as a backup fifth starter if Josh Beckett, coming off surgery for thoracic outlet syndrome, is not ready. Beckett is actually ahead of Maholm, having faced hitters, although it's possible neither will be needed for the two games in Australia.
