Much of the focus in Mariners camp will be on the infield. Seattle’s biggest offseason moves — re-signing Josh Naylor and trading for Brendan Donovan — addressed two spots. They lost a couple infielders, Jorge Polanco and Eugenio Suárez, to free agency. It’s the biggest area of turnover on what might be the American League’s best roster.
Naylor and J.P. Crawford are locked into first base and shortstop, respectively. Donovan will be an everyday player. He’s a solid defender at second base and can handle the corner outfield as well, though his below-average speed means he fits better on the infield.
