"It's just a little sore, so we'll play it safe and try to get it healthy right now," Murphy said. "That's what Spring Training's for. You get your reps in, but you want to be healthy for the season as well."
Murphy, who missed most of last spring with a right intercostal strain, noted that he only received 10 at-bats in three games that March. He went on to have his best season, batting .286 with 13 home runs and 23 stolen bases.
This year, Murphy has already received 14 at-bats in five spring games.
"So I'm way ahead of schedule," he quipped.
