Roki Sasaki completed the second start of his rehab assignment on Thursday evening, and it at least went better than his first. In that first outing, he needed 23 pitches to get out of the first inning, gave up three earned runs overall, and didn't strike anyone out.
The most worrisome aspect was his fastball velocity — down to around 93-94 MPH from the 96-97 he'd been throwing in sim games. He was pulled after two innings despite the loose expectation he'd get to three.
In his second start, he got to 3 1/3 innings, his velocity was back up to around 96, and he struck out two.
