In an announcement oddly timed with Earth Day, the Washington Mystics today inked a sponsorship deal with ExxonMobil, reports the Washington Business Journal. The massive oil company will now display courtside ads during Mystics games, a move that should place the team right alongside the Nationals as major targets of environmental protesters. Exxon will also become the official sponsor of the Mystics Student of the Week program. The Student of the Week program recognizes female high school students for excellence in math or science.
