TRENTON, N.J. -- Alex Rodriguez will play third and bat second in his minor league rehab game for the Trenton Thunder against the Reading Fightin' Phillies on Friday night.

A sellout crowd is expected at Arm & Hammer Stadium. The Thunder are expecting 150 media members -- about 10 times more than what they usually have.

Rodriguez arrived at the park at around 3:30 p.m. in a white BMW.

Rodriguez, 38, is trying to return from his Grade 1 quad strain and his second hip surgery. He is playing with the specter of being suspended hanging over his head.

As far as the Biogenesis investigation, A-Rod seems to be digging in to fight any discipline. It is not only that A-Rod wants to keep as much of the nearly $100 million he is owed -- he wants to play baseball again. The two sides are not close to making a deal at the is time.
