4. RHP Ben Brown
Ben Brown was acquired from the Philadelphia Phillies at the 2022 trade deadline in exchange for David Robertson. Since coming to the Cubs, Brown has worked his way up to the Triple-A level while becoming a respectable pitching prospect.
At 24 years old, Brown has become a potential big-league starter during his time with the Cubs. His arsenal includes a mid-to-high 90s fastball, a power curveball, a hard slider and an underdeveloped changeup. With two-plus pitches already in his repertoire, Brown would probably be a great high-leverage bullpen option and maybe even a closer.
But if he can continue to work on his other two pitches, a rotation spot is not off the table for Brown. This high upside and his placement of 86th on MLB's top 100 prospect list would make Brown a high commodity in trade talks. The Cubs are constantly developing both starters and relievers these days making Brown expendable should the Mets want him in the Alonso trade.
