Jean Segura is an Arizona Diamondback, having been acquired from the Milwaukee Brewers as part of a five player trade, according to multiple reports. Along with Segura, the D-Backs are getting pitcher Tyler Wagner, with Aaron Hill, Chase Anderson and Isan Diaz going to Milwaukee, along with cash.
Segura, a shortstop who turns 26 in March, is coming off two straight disappointing seasons. After putting up a 4 win season in 2013 and earning an All Star berth, Segura has had a .252/.285/.331 slash line in 2014-15, with a combined bWAR of 0.6. Segura has three years left of team control, and the D-Backs have to be hoping he will bounce back this year.
Wagner, 24, is a righthanded pitcher who was a 4th round pick of the Brewers in 2012. He has put up great numbers the last couple of years in the minors as a starter, but got hit hard in three starts in the majors in 2015. He was a college closer who relies on deception and a quality sinker, and profiles as a possible back-end starter in the majors.
Aaron Hill, who turns 34 in March, is getting $12M in 2016 in the final year of a backloaded 5 year, $46M deal Arizona signed him to prior to the 2012 season. He is coming off two straight years of sub-replacement-level performance, and the Brewers could either simply release him, or give him some playing time early in 2016 in the hopes that he can rebuild some trade value.
Anderson, 28, is a righthanded pitcher who has spent most of the past two seasons in the Arizona rotation, putting up a 4.18 ERA in 267 IP over that span.
Diaz, 19, is a lefty-hitting middle infielder who the D-Backs took in the supplemental second round in 2014. Baseball America has him as the #9 prospect in Arizona's system, and the #3 prospect in the Pioneer League in 2015.
In essence, the Brewers have swapped a disappointing shortstop in his mid-20s who still has some team control left, and a possible BORP, for deadweight (whose contract is presumably being subsidized in part by Arizona), a BORP, and an intriguing teenage prospect.
UPDATE -- Nick Piecoro tweets that the D-Backs are sending $5.5M to Milwaukee to subsidize Hill's deal.
