Tulsa's second home game of the season is being delayed by rain showers moving across eastern Oklahoma.The Drillers were to begin their Friday night game at 7:05. But, by 8 o'clock, the game still had not gotten underway, thanks to pesky showers and thunderstorms that dotted eastern Oklahoma.It appears there will be a brief clearing this evening, but additional showers and thunderstorms are expected, which could wash out the game. The Drillers are hosting the San Antonio Missions in the first homestand of the 2012 season. San Antonio won Thursday night, 2-1. Dan Houston will take the mound for Tulsa tonight if the game does get underway.
