Sparkman (thumb) is expected to make a few more starts at extended spring training before embarking on a rehab assignment, Gregor Chisholm of MLB.com reports.

Sparkman headed into spring training with the hope of landing a long-relief job in the big leagues, but a broken thumb has kept him out of commission since March. He seems to be back on track with his recovery program, and more details on his return date should come forth once he gets into his rehab assignment.
