What happened: Aroldis Chapman recorded career strikeout No. 1,364, setting a new all-time record for strikeouts by a relief pitcher. The milestone punch-out moved him past every reliever in major league history.

Why it matters: The record cements Chapman's standing as one of the most dominant bullpen arms the game has seen, a career built on a fastball that redefined velocity expectations for closers. It also lands at a pivotal moment: the same Chapman who emerged as MLB's premier trade target has been the subject of intense deadline speculation all month, and a historic milestone only raises his profile.

What to watch: Watch whether the milestone amplifies the trade chatter that has followed Chapman ahead of the August deadline, with contenders reportedly circling the veteran closer all summer.
