Fermin will start at third base and bat eighth in Sunday's game against the Rockies.
Fermin will be included in the lineup for the sixth time in seven games, with four of those starts coming against right-handed pitching. He could be emerging as the preferred option at third base, as rookie Blaze Jordan (122 wRC+ versus lefties, 52 wRC+ versus righties) has struggled against same-handed pitching this season.
