The Seattle Mariners have acquired Jean Segura from the Arizona Diamondbacks in exchange for Taijuan Walker.
Seattle also received outfielder Mitch Haniger and left-hander Zac Curtis, while Arizona landed shortstop Ketel Marte.
"Segura was one of the premier offensive players in the majors last season," Jerry Dipoto said. "His combination of average, power and speed is extremely difficult to find, especially at a position like shortstop and at the top of our lineup.
"We believe pairing him with Robinson Cano gives us tremendous offensive potential in the middle of our infield."
