"It felt good," he said.
Myers said he hopes to take normal batting practice on the field in the "next day or so," potentially by the time the team starts a three-game series in Philadelphia on Friday.
But this was a start and a notable step for the 24-year-old, who hasn't played in a game since June 13.
"We'll see how [his wrist] calms down and see how it feels waking up tomorrow and go from there," said Padres interim manager Pat Murphy.
The Padres and Myers have said since he had surgery that they will let the wrist dictate Myers' timeline and workload. They won't rush him, even though he has said he's determined to play again this season.
Myers first landed on the disabled list on May 19 with tendinitis in his left wrist. He came back on June 11, only to land back on the DL four days later, and Myers admits now that he rushed back too soon.
Myers, who was hitting .277/.327/.459 with five home runs and 19 RBIs in 35 games at the time he was injured, was the team's Opening Day starter in center field. But he was playing first base at the time he was hurt in May and he might have a future there.
In fact, Myers was doing defensive work early Wednesday afternoon at first base with third-base coach Glenn Hoffman, who works with the team's infielders.
