Hart (knee) began a rehab assignment at Triple-A Tacoma on Saturday, going 0-for-3 at the plate. Hart will require at least a couple more games with Tacoma, after he missed the previous three weeks of action due to a bruised right knee. The Mariners figure to bring him back from the DL when rosters expand in September, but since he's only on a one-year contract and batting .203/.278/.314 on the season, don't expect the Mariners to give him regular at-bats.

Corey Hart went 0-for-3 with a sacrifice fly in his return from the disabled list Friday. Hart's ninth inning sac fly was the M's only offense of the night against Chris Sale.

He hit just .209/.295/.353 across 37 contests before going on the DL but did homer five times while driving in 17 runs.

Corey Hart (hamstring) will begin a rehab assignment with Triple-A Tacoma on Saturday. He should only need a handful of rehab games, putting him in line for a return sometime next week.

He'll progress to doing some light running on the field on Saturday, as he continues to work his way back towards a return to the Mariners lineup.
