Hernandez (13-7, 2.67 ERA), who was named A.L. Pitcher Of The Month for August, is off to a bit of a slow start in the month of September with a record of 0-2, and an ERA of 6.75 in 12 innings of work. He'll look to rebound against a Jays offense that has sputtered in the first two games of the series.
The Blue Jays will counter with right-hander, Henderson Alvarez (8-12, 4.95 ERA). Alvarez has also struggled on the hill recently, posting a record of 2-3 with a 6.92 ERA in his last five starts.
The M's held off the Blue Jays 3-2 in last night's contest, behind a workmanlike outing from starter Kevin Millwood and four solid innings from the bullpen.
Game time is slated for 4:07 p.m. PT at Rogers Centre, and will be televised on ROOT Sports.
