2008–10 After being drafted, Guez joined the
Oneonta Tigers for his first professional season, and batted .223 over the course of 70 games in 2008. In 104 appearances, he batted .275 with 12 homers and 64 RBIs, and tied for fourth in the Midwest League with a .483 slugging percentage. Guez's performance during August, a month in which he hit .355, homered 4 times, and drove in 16 runs, led to him being named the Tigers Minor League Player of the Month.
2011–present Guez split the 2011 season between Erie and Toledo. As was the case the year before, Guez played with both Erie and Toledo in 2012. He was named an MiLB.com Organization All Star for the season, and the Scout.com Toledo Mud Hens Player of the Year. He played in the 2014 season for the Toledo Mud Hens. In December 2014, the
Milwaukee Brewers signed him and invited him to major league spring training. He began 2015 playing for the Brewers' AAA club in Colorado Springs. In his minor league career he has played all three outfield positions, but mostly played
right field and center field. ==Team Israel==
