Griffey Jr.'s Career Home Run Highlights by Year

In 1989 he hit his first Major League home run on the first pitch he saw at the Kingdome vs. Chicago's Eric King on April 10. On May 21st he hit his first inside-the-park home run vs. New York off Clay Parker.

In 1990 he hit back-to-back home runs with his teammate and father, Ken Sr., in the 1st inning at California on Sept. 14 off Kirk McCaskill.

In 1991 he hit the first grand slam of his career July 23 at New York off Lee Guetterman.

In the 1992 All-Star Game, Griffey was 3x3 with a home run off the Cubs Greg Maddux, becoming the first Mariner to hit a home run in the Mid-Season Classic.

In 1993 he began his Major League record-tying streak of home runs in eight straight games with an 8th inning blast off Paul Gibson on July 20 at New York. He surpassed Richie Zisk's 1981 club mark for consecutive games with a home run on July 25, making it six straight at Cleveland off Jose Mesa. He made it seven in a row with his fifth career grand slam off Kevin Tapani on July 27 vs. Minnesota. He tied the Major League mark with an 8th inning blast off Minnesota's Willie Banks that ricocheted off the Kingdome's third deck. A week before starting his record streak, he became the first player ever to hit B&O Warehouse at Baltimore's Camden Yards during the All-Star Game's home run hitting contest.

In 1994 he hit his 21st home run on May 23 at Oakland, breaking Mickey Mantle's record from 1956 for most home runs through May 31. He went on to hit one more home run before the end of the month. Griffey hit his 29th home run on June 15 to record his 161st career home run, surpassing the Mariners' team record previously held by Alvin Davis.

In 1995 he hit a 9th inning, two-run home run off John Wetteland to beat New York on Aug. 24 for his only career game-ending home run. The home run is considered to be one of the turning points in the Mariners' march toward their first playoff appearance. The win put the team's record at .500 (54-54), starting a stretch where the Mariners went 23-10 to force a one-game playoff with California. His five home runs in the Division Series tied the Major League record for most home runs in a post-season series. He hit one more in the League Championship Series to tie the record of six in a postseason.

In 1996 Griffey hit a blast on April 12 at Toronto off Giovanni Carrara that landed above the Hard Rock Café, estimated at over 450 feet from home plate. Later that season, he notched his first career three-homer game on May 24 vs. New York.

In 1997 he recorded his second career three-homer game on April 25 at Toronto, connecting twice off Roger Clemens and once off Mike Timlin. The second home run was the 250th of his career. Later that season, he blasted home run #20 into the dark of night in Anaheim. The estimated distance on the blast was 490-feet, although the ball was never located.

In 1998 he hit home run #56 on September 25 off Texas' Eric Gunderson, equaling his career-high and becoming the fastest in Major League history to reach 350.

In 1999 he hit grand slam homers in back-to-back games against Detroit and Toronto on April 29 and 30, becoming just the 18th player in Major League history to accomplish that feat. He belted the final home run in the Kingdome off Aaron Sele on June 27 vs. Texas.
