OAKLAND, Calif. — Oakland Athletics outfielder Stephen Piscotty will be out until at least next week after he had a melanoma removed from his right ear.

The 28-year-old Piscotty had surgery Thursday after the melanoma on the outer lobe of his ear was discovered during a routine spot check on May 28. A biopsy came back positive a week later.

Dr. Brian Parrett performed the operation at the California Pacific Medical Campus.

"From what I hear everything was pretty successful," A's manager Bob Melvin said Friday. "He didn't make a big deal of it. Even with the guys he didn't want a lot of fanfare. He didn't want it weighing anybody down. Obviously we're thinking about it."

Piscotty will be evaluated daily and the A's expect him to return next week.

General manager David Forst said the good news is the melanoma was discovered early. The A's hold an annual skin check screening for the team, coaches and employees.

"We believe it was caught early hopefully as a result of Stephen being vigilant," Forst said. "This is something that we talk about all the time with players and staff, protecting yourself from the sun and having yourself checked regularly."

Piscotty's mother, Gretchen, passed away on May 6, 2018, from amyotrophic lateral sclerosis, also known as Lou Gehrig's disease, less than a year after being diagnosed. Piscotty was playing for the St. Louis Cardinals when his mother was initially diagnosed before being traded to the A's — a move that was done partly to allow him to be closer to her.

"In his mind this is probably minor as far as that goes, which it isn't," Melvin said. "It's a big deal. He just wanted to get it over with, and hopefully if it went well get back as soon as possible. That's kind of where we are right now. We haven't made a corresponding move. We might not have to. We'll see where we are at the end of the weekend."
