Contreras went 1-for-3 and extended his hitting streak to 13 games for Triple-A Iowa on Saturday.
Even more impressive, Contreras has driven in at least one run in seven straight games. He has 39 RBI in 176 at-bats at Iowa this season and is slashing .335/.428/.585. With David Ross set to retire at the end of the season, Contreras should be with the Cubs -- possibly as the regular starter -- in 2017.
