This is how it’s supposed to work. The hitters at the top of the lineup reaching base and the hitters in the middle of the order driving them home. It hasn’t happened often for the Mariners this season, and certainly not since the All-Star break. But Saturday night at Camden Yards it all came together in a 6-3 victory over the Baltimore Orioles. Newly acquired Austin Jackson, who was batting leadoff, and hot-hitting Dustin Ackley batting behind him, combined for five hits, scored four runs and reached base six times. Robinson Cano and Kendrys Morales drove in five of the runs, and baseball, particularly scoring runs, seemed pretty easy on this night. The Mariners are 41-10 when scoring four or more runs. “That’s a good recipe for winning,” Seattle manager Lloyd McClendon said. The first example of that recipe came in the fifth with the score tied 1-1.
