Betts (oblique) is focusing on increasing his swing speed and is getting closer to kicking off a minor-league rehab assignment, MLB.com reports.
Betts has been stuck on the injured list since April 5 due to a right oblique strain. He had a brief setback in late April but seems to be back on track. Though he'll need some time in the minors to knock off rust before he's activated, Betts could still be back with the big-league club before the middle of May.
