There's belief around MLB that the San Francisco Giants and Cincinnati Reds should be among the teams looking to make major additions ahead of the upcoming trade deadline.

"One rival executive proclaimed the Cincinnati Reds and San Francisco Giants should be aggressive buyers," Rosenthal wrote, "saying it's 'open season' on the third NL wild card because of the San Diego Padres' uncertain hold on the position."

Cincinnati sits 2 1/2 games behind the San Diego Padres, the current holder of the final wild card slot and a game behind San Francisco.
