San Francisco has scouted third baseman Hank Blalock, and the Rangers have looked at the Giants' minor league system.
Last year, with the Rangers in last place, Daniels made three deals starting July 27 that were geared toward rebuilding the organization. The Rangers began Sunday in second in the AL West, 5 ½ games out in the wild-card race.
"Things are different from last year on a few fronts: The club is considerably more competitive, and we don't have the same types of players available to trade," Daniels said. "Our farm system is at a different point, too. There would have to be impact-type young players to warrant us acting."
