Garcia (elbow) threw 15 pitches in a bullpen session Saturday, Brian McTaggart of MLB.com reports.
Garcia threw 15 pitches as part of his first mound work since July 4. While Saturday's session was a major step toward resuming his rehab assignment, Garcia will likely have to complete additional bullpens before being shipped out. The 27-year-old is 14 months into his recovery from Tommy John surgery.
