Kremer (quadriceps) made his second rehab start for Triple-A Norfolk on Friday, giving up two hits and one walk in 6.2 scoreless innings. He struck out eight.
The 30-year-old right-hander fired 50 of his 79 pitches for strikes. Kremer, who's recovering from a multi-month absence with a right quadriceps strain, appears firmly on track to rejoin the Orioles at some point in early July, which will likely force Trey Gibson from Baltimore's rotation.
