O'Hearn (groin) will bat third while serving as the Royals' designated hitter in Thursday's Cactus League game against the Giants.
O'Hearn's return to the lineup supports the notion that the Royals' decision to remove him from Tuesday's game against the Mariners was mostly a matter of caution while he dealt with a left groin injury. The 28-year-old has enjoyed a red-hot spring with 10 hits -- including a pair of home runs -- across 20 at-bats.
