Depends on who else gets called up this week so they can qualify for the postseason roster. No harm in having called the arms that have been called up so far since those aren't likely to significantly impact how much control the team has over them.
Honestly wouldn't shock me to see Riley called up early so they have the option of adding him for the playoffs if they so choose. Can always send him back to Gwinnett to start the season and delay his clock if they try to game it.
If A-Jax doesn't come up today, he'll likely be added. Gohara and Fried are likely going to be added to the pen, maybe Touki and Wilson as well. Maybe Pache as a pat on the back for his good work before he goes to the AFL.
