The Cubs may lose catcher Wilson Contreras to a hamstring injury:

No team wants to lose their starting catcher, and that’s especially the case with the Cubs and Contreras. On the season, the 25-year-old is batting .274/.342/.519 in 102 games, which is obviously excellent production for someone who mans a premium position. Contreras has also been especially hot in recent weeks, as he entered Wednesday when an OPS of more than 1.100 in the second half.

Luckily the added Alex Avila, who is doing an even better job this season of getting on base.
