What happened: Aroldis Chapman recorded strikeout No. 1,364, making him the all-time leader in 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 triple-digit velocity and swing-and-miss stuff. It also lands at a moment when his value is peaking — the same Chapman who emerged as MLB's premier trade target heading into this summer's deadline.
By the numbers: Chapman's 1,364 career strikeouts are the most ever by a relief pitcher, a mark no other bullpen arm in major league history has reached.
What to watch: Watch how far Chapman extends the record with each outing, and whether the milestone adds further momentum to the trade interest surrounding him ahead of the deadline.
