Chicago, IL -- (Sports Network) - Chicago White Sox outfielder Ken Griffey Jr. belted his 609th career home run on Wednesday to tie Sammy Sosa for fifth place on the all-time list.

Griffey drilled a two-out, two-run homer in the second inning against Seattle's R.A. Dickey for not only the milestone homer, but his first in a White Sox uniform.

Acquired from Cincinnati at the trade deadline, Griffey was 10-for-44, including a first-inning single on Wednesday, with the ChiSox before the home run. He had gone 46 at-bats without a long ball.

Griffey hit his 600th career home run on June 9 at Florida with the Reds.
