The Cubs announced their 40-man postseason player pool on Thursday, which includes top pitching prospect Brailyn Marquez.
The group consists of players eligible for the Cubs during their postseason run. Those currently on the 28-man active roster are included, in addition to a combination of 12 players currently on the injured list or those who trained at the South Bend alternate site.
Marquez, 21, has been training at the Cubs' alternate site in South Bend this season. He's the No. 64 prospect in baseball, per MLB Pipeline, pitching as high as advanced-A Myrtle Beach last season. In 22 starts, he posted a 3.13 ERA, striking out 128 in 103 2/3 innings.
With Rowan Wick on the injured list (left oblique strain), Marquez offers the Cubs a potential big bullpen arm for October. The lefty's fastball velocity touches 100 mph.
Each team must submit a 28-man active roster each postseason round. Those not on the active roster will train at Wrigley Field, as the South Bend site shut down for the season.
