The Guardians placed Arias on the 10-day injured list Tuesday with a left hamstring strain, Tom Withers of the Associated Press reports.
Arias suffered the injury during Monday's game versus the Royals while legging out a double. It's considered a moderate strain, so Arias will need more than a minimum 10-day absence. Brayan Rocchio will likely shift over from second base to be the Guardians everyday shortstop while Arias is sidelined. Second base should be manned primarily by Daniel Schneemann against righties, though Juan Brito has been recalled and is starting at the keystone Tuesday versus a lefty.
