The machine churning out top-of-the-line position players in the Cubs' farm system isn't showing any signs of slowing down.

On a day when homegrown products Kris Bryant, Javy Baez, Albert Almora, Willson Contreras and Jeimer Candelario all started for the big league team, the Cubs named infielder Ian Happ their minor league player of the month, perhaps a preview of the next top prospect to generate tons of excitement.

Happ, who the organization drafted with its first-round pick a year ago, hit .422 in the month of June with a .500 on-base percentage and a .699 slugging percentage, totaling nine doubles, four homers, 13 runs scored and 21 RBIs in 26 games between Single-A Myrtle Beach and Double-A Tennessee.

Since joining the organization last season, Happ has posted a .288 batting average with 35 doubles, seven triples, 18 home runs and 83 RBIs in 146 games.

The Cubs also named Preston Morrison their minor league pitcher of the month. Morrison, who's playing at Single-A South Bend, went 4-1 with a 0.83 ERA in five starts.
