Now he's getting another look. In Tuesday's 7-1 loss in Atlanta, Murphy belted a first-inning home run. And he went 2-for-5 in the series opener against the Braves on Monday.
In Miami's win over the Padres on Sunday at Marlins Park, Murphy delivered a two-run triple.
Before getting another big league shot, Murphy made the most of his time at Triple-A New Orleans. In 33 games, he batted .302 with 13 home runs and 25 RBIs.
"I knew when I was going to go down, I was going to get some consistent playing time," Murphy said. "The No. 1 goal is getting confidence back, getting in the swing of things.
"[When the season started], it was kind of a different role than I was used to. I felt like I was off, and when you do get that one chance, it was hard. But I feel like there is more of an opportunity this time around, and hopefully I can run with it."
When Murphy was designated, he could have refused the assignment, which would have made him a free agent.
Had he done so, he would have forfeited the remainder of his $560,000 contract. The Marlins signed him to the guaranteed contract last offseason, avoiding arbitration.
For family reasons, Murphy felt remaining in Miami's system was in his best interest.
"I didn't really have much choice," he said. "This year is looking out for family more financially. Obviously, if I opted out, I would have had to forfeit the rest of my earnings this year. That's something I didn't really want to do."
Murphy and his wife also have a small child, so staying became a priority.
"Having a kid, that is something that was important," he said. "This year is the first year I ever had a guaranteed deal. That's why I went down there. I said, 'Who knows?' If I go down there, do well and something else happens. ... Stuff did happen. I did well down there, and I'm back. I'm glad I stuck with my decision."
