Red Sox right-handed reliever Tyler Thornburg pitched a scoreless inning and struck out two for Triple-A Pawtucket in his latest rehab outing Thursday.

Thornburg underwent surgery to treat thoracic outlet syndrome last June.

Thornburg has a 1.93 ERA (9 1/3 innings, two earned runs), 1.29 WHIP and .167 opponent batting average in 11 appearances for Pawtucket over two rehab assignments. He also allowed two earned runs in 1 2/3 innings for Double-A Portland.

He recorded both strikeouts swinging. The other out came on a grounder back to the mound. One batter reached against him on an error by the shortstop.

He threw 20 pitches (11 strikes). He topped out at 96 mph and sat at 94-95 mph, per the PawSox.
