The Seattle Mariners and Arizona Diamondbacks have agreed to trade RHP Taijuan Walker and IF Ketel Marte in exchange for IF Jean Segura, OF Mitch Haniger, and LHP Zac Curtis. The 2016 National League leader in hits, Jean Segura will now be wearing an American League jersey while the promising Walker joins a depth-heavy rotation in the desert.
How this affects Seattle's IF future outlook: With Robinson Cano firmly entrenched at second base, Jean Segura will move back over to shortstop which was his primary position before moving to second base last year in Arizona. While the team was originally relying on Ketel Marte to hold down the position, his sluggish 2016 season and subpar defensive performance made him a candidate to be replaced. Mariners GM Jerry Dipoto replaced him with one of the best offensive players at the position, Jean Segura who is coming off of a .319/.368/.499 season with the snakes. Instead of having Marte under team control for five seasons though, the M's will get Segura for the next two seasons as he enters his last two years of arbitration before being eligible for free agency.
How this affects Seattle's overall future outlook: OF Mitch Haniger and LHP Zac Curtis appear to be throw-ins, but could still make an impact at the major league level. The 26 year-old Haniger could be a solid fourth outfielder after productive minor league seasons in 2015 and 2016 before a mediocre debut at the big league level. The southpaw Curtis was viewed as a future dominant reliever before last season's struggles. However, the 24 year-old has a lot of time to get back on track and it should be noted he started 2016 in High-A ball before his disappointing major league debut. He could be a factor in Seattle's future bullpens. Now we get to the centerpiece of the deal, Jean Segura. Segura instantly becomes a huge offensive upgrade over Ketel Marte in the lineup and can be the spark atop of the lineup that is a catalyst for Cano, Nelson Cruz, and Kyle Seager like he was for Paul Goldschmidt, Jake Lamb, and Yasmany Tomas last season. Seattle will have an important decision to extend Segura or hand the keys to prospect Drew Jackson who should be ready by 2019.
Bottom Line: Taijuan Walker could turn into a frontline starter in Arizona, but Seattle sparked up their offense for the next few years with Segura.
