What happened: Kevin Gausman can block trades to the Cincinnati Reds, Milwaukee Brewers, Detroit Tigers, New York Mets, A's, Chicago White Sox, Pittsburgh Pirates, and Seattle Mariners. Ken Rosenthal reported the details of the contract clause on Wednesday.

Why it matters: The specific parameters of his contract clarify his market ahead of the deadline. With several major contenders omitted from his no-trade list, a broad pool of buyers remains in play for his services. Gausman has emerged as a major trade candidate this month.

What to watch: Teams not on the blocked list will continue evaluating potential trade packages before the deadline.
