Winning a big-league job out of camp would have a profound financial effect on the Powell family. Powell’s salary at the major league level could be close to $500,000; in the minors, he might make a bit less than $100,000.

Treatment for Powell’s daughter was time-consuming and expensive, and since her death, medical bills have continued to accumulate as the couple’s two other children — Holden, 3, and Ellie, Izzy’s twin sister — have undergone extensive genetic mapping tests to determine the extent to which they might be at risk for the disease, which doctors believe is hemophagocytic lymphohistiocytosis.

Powell’s wife, Allyson, said the family already faced medical bills of several hundred thousand dollars and was trying to figure out how much will have to come out of their pockets.

One issue has been that the family’s insurance coverage changed considerably each time Powell bounced between the majors and the minors. They were not covered at all this past off-season, when he became a free agent. On top of that, for the last several years, Landon Powell has needed medication to combat a different genetic disorder, autoimmune hepatitis.

Allyson Powell said the family would be at peace whatever the outcome of her husband’s career. But she acknowledged that the difference between levels would be drastic.

“It would be wonderful to make the big league team and not have to worry about bills,” Allyson Powell said. “If we made the big league team, they wouldn’t be a bother.”

People who run baseball teams take a quantitative view of the game, but they are not devoid of sympathy. Mets coaches and front office officials have been well aware of Powell’s situation. They know how much their decisions could affect him personally, but they know they cannot let that affect their final evaluation process.
