2B Jackson Holliday, Baltimore Orioles5 of 10Mitchell Layton/Getty ImagesAge: 22Contract: Arbitration-eligible through 2030Stats: 66 G, 111 OPS+, 14 XBH (6 HR), 1.0 WARJackson Holliday was an unexpected addition to the pre-deadline rumor mill, but after the Orioles sent Adley Rutschman to the Red Sox in a surprise blockbuster, it's clear change is coming in Baltimore.
