Mariners deal Walker to D-Backs for Segura

The Seattle Mariners have made a pretty significant deal tonight, sending pitcher Taijuan Walker and shortstop Ketel Marte to the Arizona Diamondbacks for shortstop Jean Segura, outfielder Mitch Haniger and left handed pitcher Zac Curtis.

Segura, who turns 27 in March, was one of the best shortstops middle infielders in baseball last year, putting up an 867 OPS, and was also very good for the Brewers in 2013.  However, he was basically replacement level in 2014 and 2015, and Arizona picked him up for little last offseason from Milwaukee.  Segura has two years of team control left, and if he replicates his 2016 season, Seattle has a terrific middle of the infield with him and Robinson Cano.  If he's 2014-15 Segura, however, he's close to useless.

Hanover, who turns 26 next month, got some time in the majors for Arizona in 2016, and has put up some big numbers in the minors, though he seems like a fourth outfielder type.  Curtis, 24, is a reliever who has put up big strikeout numbers in the minors, but who struggled in the big leagues in 2016.

To land the trio, Seattle parted with significant young talent.  Walker, 24, spent the 2016 season in the Seattle rotation, and while he was homer prone, he has a terrific arm and significant upside.  Marte, meanwhile, just turned 23, and while he didn't hit last year, he had a nice debut in 2015.

The initial consensus seems to be that the M's paid a pretty steep price to land Segura.
