BOSTON — The Red Sox made a somewhat surprising roster move Monday by designating utility infielder Pablo Reyes for assignment to clear a roster spot for trade addition Garrett Cooper. On Tuesday, manager Alex Cora pointed to Reyes’s defense as a reason why the move was made.

Reyes, who played 21 games (14 starts) for the Red Sox at all four infield positions, ranked in the second percentile in range/outs above average at -4, according to Statcast. He made four errors in 78⅓ innings filling in for Rafael Devers at third base while also seeing 39 innings at second base and about a dozen each at first base and shortstop. Mixed with a .183 average and .451 OPS in 64 plate appearances, the downturn was enough to cut bait.
