Why it matters: Sitting 12 games under .500, Boston is expected to be a major seller before the August 3 deadline. The elite performance of Aroldis Chapman makes him the top rental option for contenders seeking late-inning stability as the market heats up.
By the numbers: Chapman holds a 0.44 ERA with 14 saves and 28 strikeouts across 20.2 innings this season. He has limited opponents to a .117 batting average while maintaining a 0.92 WHIP.
What to watch: Bidding is expected to intensify as the trade deadline nears, with experts projecting a significant return for the left-hander. Chapman’s market will likely set the tone for the relief pitcher landscape in July.
