The Mariners spot the Yankees four runs, then hammer starter Jimmy Key and five other pitchers for 19 hits to win, 10 – 5. Seven Mariners collect two or more hits, and Edgar Martinez drives in four runs. A wild Key takes his 5th straight loss, while Yankee reliever Mariano Rivera records four outs to stretch his runless innings to 21 2/3. The Yanks will place Key on the disabled list.
