"It's great. I was really excited," said Langwell, who's yet to pitch in a Major League game. "I'm just really looking forward to getting out there and getting an inning under my belt."
The right-handed reliever takes the place of lefty Scott Barnes. Barnes was optioned to Columbus a day after giving up five runs in an inning during the Indians' 9-2 defeat, which lasted until 3 a.m. because of rain delays and saw the Tribe use five relievers.
Langwell, 27, has gone 2-1 with a 2.30 over 20 appearances (including one spot start) for the Clippers this season. He has a save to his name, and he held batters to a .243 batting average. Right-handed hitters hit just .186 against Langwell, who also averaged 7.6 strikeouts per nine innings.
Cleveland picked Langwell in the 11th round of the 2008 First-Year Player Draft.
While there's no guarantee that his big league debut will happen on Saturday, Langwell said, "I'm sure I'll be one of the guys in the mix if we need that."
