The center fielder was on base five times in Tuesday's 9-8 loss to the Royals. Jackson was 3-for-3 with a pair of walks and three runs scored.
"He's always real good after a day off," Leyland repeated several times before Tuesday's series opener and then again after the contest.
Jackson has indeed had success following a day off -- be it for the team or just personally. In games following off-days this season, he's batting .383 with six doubles, two home runs, 10 walks, 11 RBIs and 13 runs scored.
Tuesday's performance followed a series against the Angels in which Jackson didn't even reach base. He went 0-for-13 with three strikeouts and grounded into a double play.
"It's just good to start getting on base, try to help win ballgames by getting in scoring position," Jackson said. "I haven't been doing the best at that, but it felt good to get on there [Tuesday]."
Jackson spoke of the benefits of getting a daylong break from the game.
"You get to get away from it for a little bit, clear your mind and rest your legs a little bit and recover and come back and feel refreshed," Jackson said. "Taking a little mental break for a day, it's good for your body as well as your mind."
