Alvarez suffered a hamstring injury during Monday's game against the Indians, Mark Berman of Fox 26 Houston reports. He went 2-for-3 with a home run, double, a walk and two RBI in Houston's 4-3 win.
According to manager Dusty Baker, Alvarez suffered the injury on his double in the seventh inning, though it's unclear if the slugger will be forced to miss any time as a result. The team is set to re-evaluate Alvarez early Tuesday before assessing his status for the second game of the series later that day.
