Robertson throws perfect inning in first rehab appearance

Sidelined with an oblique strain for the last month, David Robertson made his first minor league rehab appearance for Triple-A Empire State this afternoon. He retired all three batters he faced — grounder to second, strikeout, fly ball to right — and threw eight of eleven pitches for strikes. Assuming he feels fine tonight and tomorrow, Robertson will probably make another rehab outing early next week. Joe Girardi indicated that his setup man could rejoin the team in time for next weekend’s series in Washington.
