Top 5 Chicago Cubs pitching prospects that have yet to make their MLB debut

4. Ben Brown

The Cubs' no. 7 prospect is the 6'6 right-hander Ben Brown. Brown was drafted by the Phillies in the 33rd round of the 2017 draft, and traded to the Cubs last August in exchange for closer David Robertson. Brown had an excellent season across the Phillies High A and Cubs Double-A teams, tossing 104 innings with a 3.38 ERA and striking out a staggering 149 batters. Brown's arsenal features a mid-90s fastball that tops out around 98 mph, and a high 80s slider with a powerful curveball to boot.

Brown is trying to introduce a changeup to that mix, and if he is successful, that four-pitch mix could translate well into being a major league starter. As things stand though, Brown could be a lethal weapon out of the bullpen. The Cubs recently added Brown to the 40-man roster to protect the 23-year-old from the rule 5 draft, so there is a chance we see Brown at Wrigley by the end of the 2023 season.
