"A scenario exists in which the Arizona Diamondbacks would both sign free agent third baseman Alex Bregman and keep second baseman Ketel Marte. Those two, combined with right fielder Corbin Carroll and shortstop Geraldo Perdomo, would give the D-backs four of the top position players in the game," Rosenthal wrote.

After signing slugger Munetaka Murakami, the White Sox could make another splash by bringing Tatsuya Imai to Chicago.
