Reds' Nick Martini: Begins rehab assignment

Martini (thumb) began a rehab assignment with Triple-A Louisville on Saturday.

Martini had originally been targeting Tuesday as the start date for his assignment, so it's possible the 34-year-old is ahead of schedule in his recovery. It's unclear how many games he will play in the minors, though there's still a good chance he rejoins the Reds before the end of the season.
