4. Jean Segura
Years as a Brewer: 2012-2015
There a lot of people lamenting this season on how good the Brewers would be with Jean Segura still at shortstop. He is currently performing magnificently with the Mariners after being traded after one season with the Diamondbacks. The Brewers also received Chase Anderson and Isan Diaz in the trade with Arizona. The former was the Opening Day starter this season and the latter was a big piece that helped procure Christian Yelich. Acquisitions are not made in a vacuum.
All of that being said, Segura was an All-Star for the Brewers in his relatively short stint in Milwaukee. He came over from the Angels in the trade that sent out Zack Greinke near the trade deadline. After showing potential in 44 games after the trade, Segura burst onto the scene in his 2013 All-Star campaign. He hit .294, stole 44 bases, belted 12 home runs, and hustled his way for 10 triples. Those numbers are awfully similar to what Listach did in 1992.
Tragedy hit Segura in July of the next season. He learned after a game that his 9-month old son had passed away in his native Dominican Republic. He really was not the same player after that unspeakable tragedy. Segura hit .246 in 2014 and .257 in 2015 with the Crew before being traded to Arizona.
Segura has been a .300 hitter in his last 3 campaigns and is on pace for his best season at the age of 28 in Seattle. He certainly would look good in a Brewers uniform. The guess here is that a change of scenery was needed.
