Bruce is a powerful hitter, sure. But the Phillies would be getting a solid defender as well.
Bruce is by no means a Gold Glover. But he doesn’t kill you defensively. His -3.6 dWAR for his career is not pretty. But if you look deeper, he’s mostly been up-and-down overall.
He’s got a very good arm (86 career assist), and above average range (2.17 RF/9).
Bruce can be prone to the occasional blunder, but with a .984 fielding percentage for his career, he’s shown he’s far from a defensive killer and more than capable of holding his own.
Not to mention, the relief of playing next to a gold glove caliber center fielder in Odubel Herrera, Bruce would be just fine.
