Here's what Eaton had yesterday in a rehab start at Frisco:
4 IP, 3 H, 1 BB, 3 K in 4 IP
He said his change and curve were working fine, with a fastball between 89-93.
MLB.com says that "The next and final rehab start for Eaton will be for Triple-A Oklahoma when the team travels to Iowa on Thursday. He will pitch five innings or 75-to-80 pitches"
If all goes well, he'll be starting on the 25th against the Yankees. He hasn't pitched since coming to Texas, so I don't know how he'll fare at Ameriquest, but I think he'll be a shot in the arm for Texas and pitch just fine.
