Simpson said that Yu Darvish, who was introduced Friday, was the main off-season target.
Simpson said that he had reservations about signing Darvish until a long presentation in Fort Worth by club officials. As an oilman, he wanted to make sure that the Rangers wouldn't be wildcatting with Darvish but instead would get production. The front-office said the investment was sound.
"I've got to support my guys," Simpson said.
