Lansing, Mich. The scheduled double-header between Ohio State and Michigan State Saturday at Oldsmobile Park has been postponed. Steady rain and the threat of continued rain prompted the action. The two teams will try Sunday to play two seven-inning games starting at 1:05 p.m. … weather permitting. Just one game has been played in the scheduled four-game series. Ohio State won an extra-inning affair Friday night, 4-3, behind an 11th-inning home run by Ryan Dew and a terrific, 10-inning pitching performance from Jake Hale.
