Campbell recently tweeted:
Astros pitcher J.A. Happ (strained right oblique on Tuesday) is feeling better and plans to make scheduled Sunday start at Philadelphia.
Happ plans to start at Citizens Bank Park; in his last start at Philadelphia, Happ threw six and a third innings and gave up two runs in an Astros win. If he's able to make the Sunday start, he would square off against the pitcher he was traded for: Roy Oswalt. The Astros open up with the Phillies on Friday and will have a three-game series in Philadelphia.
Astros social media guru Alyson Footer also tweeted that Happ will stretch and throw during batting practice today. Happ's relative healthiness would be a nice stroke of good luck for the Astros, who have already lost Clint Barmes and Jason Castro to injuries in spring training.
