Overview

• Cristian Javier has been activated from the 60-day injured list and is slated to start Monday’s opener against the Red Sox after roughly 15 months of recovery.
• Colton Gordon, who logged a 5.27 ERA over 66⅔ innings in his MLB debut, was optioned to Triple-A Sugar Land to continue his development and preserve depth.
• Cooper Hummel was designated for assignment to free a 40-man roster spot, and outfielder Jacob Melton was recalled as his replacement on the active roster.
• Manager Joe Espada praised Gordon’s work and said the left-hander will focus on building arm strength in Triple-A until Houston needs him again.
• The moves come as the Astros hold a narrow AL West lead with a 4-5 August record while the Mariners close in on the division pace.
