The 24-year-old infielder belted two triples in Sunday's 13-8 loss to the Twins and is hitting .405 in Spring Training.
"He's had an outstanding spring. He's lighting things up," said Red Sox manager John Farrell. "The way he runs the bases … you love the bat speed, the athleticism in multiple ways. So everything he can possibly do, he's doing. Where this leads us over his final 10 days, we'll figure all that out, but he's done himself a world of good in this camp."
Boston already has one of the best utility players in the game in Brock Holt, who is a left-handed hitter.
