In his second rehab outing of his comeback from March back surgery, Brett Anderson threw 64 pitches — 44 for strikes — in four innings Tuesday for Single-A Rancho Cucamonga, striking out eight.

Pitching on four days’ rest, Anderson allowed two unearned runs on three hits, while walking one. The two unearned runs came in a first inning that featured two errors and a double steal of second and home.

At one point, Anderson struck out five consecutive batters.
