Danica Patrick will announce on Tuesday in Phoenix her decision to drive a part-time Nationwide Series schedule for JR Motorsports in 2010, multiple sources told ESPN.com on Monday.

ESPN.com reported last month that Patrick was in the final stages of negotiations with JRM to compete in about a dozen races in a No. 7 -- her number in IndyCar -- Chevrolet with GoDaddy.com as the sponsor. The source said that has not changed.
