Word is coming out that Mac will be at LSU, LSU Baseball looking good. Time has passed with the Astros. Welcome Tiger
He probably wanted to pitch for a team that could back him up with hits and runs better than the Astros.
I don't think they were trying to low ball him so much as being total dicks to that Aikins kid to get Mac more cash. In their efforts, Asstros lost even more signatures and Mac is officially a Tiger.
