The prospect formerly known as Trent "Clark" changed his last name to honor his mother, but by either name he is one of the Brewers' most promising youngsters. Just how bright his future is, is uncertain at this point, though, as he struggled to hit for both average and power in 2017 for the second year in a row. One thing Clark definitely succeeds at, however, is getting on base: he has posted a .372 OBP as a professional, and he finished second among all minor leaguers last season with 98 walks. With him still reaching base often despite striking out a whopping 141 times, Clark was a threat on the basepaths, and he made major strides in that area, upping his success rate from 33 percent the year before to 88 percent in 2017. Clark is a former first rounder who will be just 21 years old for the entire 2018 campaign, so he has the time and skills to diversify his portfolio at the plate. He has slid down prospect lists, but his pedigree could help him rebound like fellow Milwaukee outfield prospect Monte Harrison did last year.
