Representing Pasco, WA, Kennewick, WA and Richland, WA, the Tri-City A's joined the Northwest League in 1969. The Oakland A's affiliate went 41-38, second in the four-team circuit and led the NWL in attendance (28,586). Billy Herman managed the club, which somehow achieved their fine record despite being outscored 426-501. The team had three All-Stars - P/3B Don Stanhouse (5-1, 3 Sv, 3.10 on the hill, .267/~.346/.364, a league-high 5 sacrifice flies) made it as a pitcher, SS Tommy Sandt (.317/~.383/.379, 16 SB in 17 tries, 3rd in the NWL in average, led the league with 63 runs) split the vote at SS and Steve Cooley (.314/~.434/.462, a league-leading 55 walks and 62 RBI, 4th in average) made it as an outfielder. The Tri-City region switched affiliations in 1970 to the San Diego Padres and were renamed the Tri-City Padres.
They were also sometimes listed as the "Tri-Cities A's".
