Callis/Mayo:
27. Cubs
Mayo: Nick Allen, SS, Parker HS (San Diego) - I've had Allen in this spot pretty much from the get-go and I see no reason to change course now.
Callis: Tanner Houck, RHP, Missouri - Chicago needs pitching much more than hitting and could grab two college arms with its multiple first-rounders. Coming into the year, the Cubs wouldn't have expected a shot at Houck, who originally projected as a top-10 selection.
30. Cubs (Compensation pick for Fowler signing with the Cardinals)
Mayo: Sam Carlson, RHP, Burnsville (Minn.) - Carlson is one of those high school arms who could go much higher based on talent, but could settle down to the bottom of the round as prep right-handers often do.
Callis: Drew Rasmussen, RHP, Oregon State - Rasmussen also has come back nicely this spring, hitting 98 mph after having Tommy John surgery in March 2016. If Chicago wants a position player, it could snag California high school shortstop Nick Allen, the Draft's top defender.
