If order to acquire a player believed to help your team, the equation holds you give up something viewed as equal.
That was how Mike Hazen, general manager of the Arizona Diamondbacks, deduced from the trade on Thanksgiving Eve. That’s when Hazen acquired right-hander Taijuan Walker from the Seattle Mariners in exchange for infielder Jean Segura. As part of this five-player deal, the Diamondbacks also picked infielder Ketel Matre, a switch-hitter who the Diamondbacks envision as a shortstop or second baseman. Also going to Seattle was outfielder Mitch Haniger and relief pitcher Zac Curtis.
