The Seattle Mariners' 1995 season was the 19th in the history of the franchise. The team finished with a regular season record of 79–66, tying the California Angels for first in the American League West. In a one-game tiebreaker, the Mariners defeated the Angels 9–1 to make the postseason for the first time in franchise history.[1]
Ken Griffey, Jr. suffered a severe wrist injury on May 26 while making a catch at the wall that would sideline him until mid August. The team would stay afloat at .500 however, and after Junior returned they managed their historic late season comeback against the California Angels.[6]
The Mariners honored the West Coast Negro Baseball League Seattle Steelheads when they wore 1946 Steelheads uniforms on September 9, 1995 at home against the Kansas City Royals. The Royals wore Kansas City Monarchs uniforms.[7] The Mariners beat the Royals 6 to 2 in front of 39,157 fans at the Kingdome.[8]
Randy Johnson won the Cy Young Award. The award came at the end of a banner year. Johnson (18-2, 2.48 ERA, 294 strikeouts) narrowly missed becoming the first AL Triple Crown pitcher (leading the league in wins, ERA, and strikeouts) since Detroit's Hal Newhouser accomplished the feat in 1945.[6] His .900 winning percentage broke Ron Guidry's 1978 record, and his strikeouts per nine innings ratio of 12.35 broke the record held by Nolan Ryan.[6]
August 15, 1995: The Mariners traded a player to be named later to the Kansas City Royals for Vince Coleman. The Mariners completed the deal by sending Jim Converse to the Royals on August 18.[12]
Note: Teams played 144 games instead of the normal 162 as a consequence of the 1994 strike. Seattle and California each played 145 games due to the one-game tiebreaker.
