What happened: Jonah Heim, Jose Suarez, Hogan Harris and Luis Medina also fit the Athletics' smaller-scale deadline possibilities. Heim can reach free agency after the season, while Suarez is controlled for another year.

Why it matters: Moving Heim would leave Brian Serven as the primary catcher for the final two months. The remaining club control attached to Suarez, Harris and Medina could raise the Athletics' asking prices.

What to watch: Heim's catching market and offers for controllable relievers will determine whether the Athletics move beyond their veteran rentals.
