Guillorme sat out Los Angeles' first-half finale last weekend due to back tightness. It doesn't sound like a major concern moving forward.
It's probably safe to call him day-to-day for now. Brandon Drury will make the start at third base instead.
Rendon will get a rest in the final game before the break. Willie Calhoun will serve as the designated hitter and Luis Guillorme will be at the hot corner.
