What happened: Boston Red Sox prospect Gage Ziehl is drawing attention as a possible trade chip ahead of the August 3 deadline. The minor league pitcher continued his strong stretch on Sunday, striking out eight batters over five scoreless innings against the New York Yankees' Double-A affiliate.

Why it matters: Boston rides a 13-game win streak into Baltimore and is positioned as a buyer in the market. Ziehl, originally acquired as part of the Jordan Hicks deal, could be leveraged to reinforce the major league club for a postseason run.

What to watch: Watch for Boston to evaluate trade packages involving their minor league pitching depth over the coming weeks.
