As anticipated, the first wave of September reinforcements joined the Mariners prior to Friday’s series opener against Oakland at Safeco Field.
In addition to putting just-acquired pitcher Mike Leake on the active roster and activating outfielder Jarrod Dyson from the disabled list, the Mariners promoted five players from Triple-A Tacoma.
So seven new bodies in all.
By placing reliever David Phelps on the disabled list because of renewed elbow problems, the Mariners were able to recall reliever Dan Altavilla before he served the required 10 days after an optional assignment.
The Mariners also recalled reliever Ryan Garton and starting pitcher Andrew Moore from Tacoma.
