The Pittsburgh Pirates have made some trades and will make more ahead of the deadline on July 31, but one of their top assets will likely not move.

If Pittsburgh deals a starter at the deadline, it probably won't be their highest-priced arm. Visit MLB Trade Rumors for more.

Mitch Keller is one of the biggest starting pitcher names on the trade market heading toward the MLB deadline. That sets the Pittsburgh Pirates' right-hander up for a very unusual Monday night. You see, Keller is the starting pitcher for the Pirates in San Francisco in a game that will start at 9:45 p.m. on clocks in Pittsburgh.
