Carroll started in right field and went 0-for-3 in Monday's spring game against the Guardians.
Carroll made his first appearance in the field since returning from surgery to remove a broken hamate bone. His previous five Cactus League appearances were as the designated hitter. With no setbacks as a fielder, Carroll will be the Opening Day starter in right field, Alex Weiner of Arizona Sports reports. He's had just 17 at-bats over six games this spring, far fewer than in previous years, so there could be some lag to start the regular season while he gets his timing down.
