The Rays activated Jax (elbow) from the 15-day injured list Wednesday.
Jax is set to rejoin the Rays' rotation with a start Wednesday against the Mets at home. The right-hander has been shelved since early August with elbow discomfort but came out of his lone rehab start with no issues. Jax threw only 42 pitches in that outing, so his workload will be limited Wednesday.
