Wilson has played in parts of seven Major League seasons. He has a career batting average of .201, and he was hitting .145 this season for the Rays. The Rangers still have Carlos Corporan on the disabled list. Corporan is expected to be back some time next week.
Dyson was acquired just before the 3 p.m. CT non-waiver Trade Deadline. The Rangers had conversations all day with clubs about pitcher Yovani Gallardo, but the team did not get a suitable offer. Texas will hold on to him for now.
Trades can be made in August for players claimed on waivers.
