The Brewers are planning to select Small's contract from Triple-A Nashville ahead of Monday's doubleheader with the Cubs, Jeff Passan of ESPN.com reports.
Milwaukee hasn't officially confirmed his call-up or announced their plans for Small, but he's expected to slot into the rotation to start in one half of the series-opening twin bill at Wrigley Field. One of Milwaukee's top pitching prospects, Small dazzled over his eight starts at Nashville this season, logging a 1.88 ERA, 1.13 WHIP and 49:21 K:BB across 38.1 innings. Whether he makes any starts beyond Monday will likely hinge on how he performs against the Cubs; if Small excels in his MLB debut, the Brewers could opt to move to a six-man rotation that features the lefty as a replacement for Freddy Peralta (lat), who is without a clear timeline to return from the 15-day injured list.
