Montgomery gets little support in return to rotation

Houston Astros' Lance McCullers Jr. exits game with forearm discomfort

McCullers lasted just 1 2/3 innings against the Chicago White Sox in his second start since returning from the injured list.

Lance McCullers Jr.'s second start since returning from the injured list was cut short on Sunday when he exited the game with forearm discomfort.

McCullers allowed three runs on four hits and two walks in 1 2/3 innings against the Chicago White Sox.

The Astros announced that McCullers will undergo an MRI on Monday to determine the extent of the injury.

This is the latest in a string of injuries for McCullers, who has been limited to just 12 starts this season.

The Astros are hoping that McCullers' injury is not serious and that he will be able to return to the rotation soon.

In his absence, the Astros will likely turn to Cristian Javier or Bryan Abreu to fill his spot in the rotation.

Javier has been impressive in his starts this season, posting a 2.70 ERA in 10 starts.

Abreu has been used primarily as a reliever this season, but he has made two starts and has a 3.60 ERA.

The Astros are hoping that either Javier or Abreu can step up and fill the void left by McCullers.
