Trent Grisham

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.

Clark was dominant in rookie ball in 2016, but elevation to full-season ball in the Midwest League exposed the 19-year-old's weaknesses. He struck out 62 times in just 59 games for the Wisconsin Timber Rattlers, was caught stealing 10 times and succeeded on just five attempts, and mustered just a .231/.346/.344 batting line. Still, Clark remains one of Milwaukee's most promising prospects -- an athletic outfielder with the ability to stick in center field and a promising hit tool that has drawn comparisons to Michael Brantley, another former Brewers outfield prospect. He's still a few years away, but his stock will be worth watching.

Clark was selected 15th overall by the Brewers in the 2015 draft, and he wasted no time justifying that decision. Despite sitting out some time after a scary collision with the outfield wall, Clark slashed .309/.422/.442 to go with 20 stolen bases in the Arizona Rookie League. He also put up similar numbers in the Pioneer League with rookie-level Helena. The left-hander did strike out fairly frequently (18 percent of the time in the Arizona League), but he also showed good discipline while producing a 15 percent walk rate. At only 19 years old, Clark is already a top prospect and has lots of potential to be a major force with the Brewers in the future.
