"I tried to soak it in a little bit," he said. "It was a very cool experience. It was everything I thought it would be."
Myers was 0-for-4 with a strikeout in the Rays' 5-1 loss to the Red Sox at Fenway Park.
The right fielder came to bat in the second inning with two runners on and no outs after Evan Longoria and James Loney drew back-to-back walks.
Myers swung at the first pitch and popped up to shallow center field. Myers said he was a little overanxious.
"I'm not a guy that takes a lot of pitches anyway," Myers said. "I should have got a better pitch to hit right there. I just got out of my approach a little bit, obviously, being the first at-bat."
Myers also played right field and batted sixth in the latter game of the teams' day-night doubleheader.
The halt in the fifth inning lasted 2 hours, 59 minutes, prolonging a game that had already been postponed because of rain on April 12.
The Red Sox invited fans who stuck out the first game to return for the second for free. The opener ended after the scheduled 7:05 p.m. start time for the nightcap — and by that point, with little turnaround time, Game 2 fans were already wandering into Fenway Park for the scheduled 8:05 first pitch.
