The new front office in Arizona makes their first major move, dealing off SS Jean Segura plus two minor league names to the Mariners for RHP Taijuan Walker and IF Ketel Marte (not sure if he's named after the vodka or vice versa). The Snakes just acquired Segura from the Brewers a year ago and got a great season out of him [20 HRs, led NL in hits, 13th in MVP] but he's eligible for FA after 2018 so this smells like a youth movement thing for them. The just-turned 24 y/o Walker was a top of the charts prospect a couple years back although in two full seasons has yet to keep his ERA under 4.00 Marte, 23, was more or less the M's full-time SS this past season. Seattle also gets CF prospect Mitch Haniger, former 1st round draft pick of Milwaukee who got some playing time with Arizona in 2016, and reliever Zac Curtis who adds to the variety of ways ML moms and dads have found to spell Zack/Zach. Plus there's that guitarist Zakk that Piazza used to like.
