Velasquez (biceps) has joined the Phillies in San Francisco, Todd Zolecki of MLB.com reports.
Velasquez has been progressing smoothly as he comes back from a biceps injury that's sidelined him since early June. In his rehab start on June 22, the 24-year-old pitched five innings of one run ball while only allowing two hits and one walk. He threw 76 pitches -- 51 of which were strikes -- and hit 97 mph on the radar gun. If he doesn't encounter any setbacks over the weekend, the righty should be back in the Phillies rotation sometime next week.
