Oakland, CA (Sports Network) - Holding the outright AL West lead for the past 176 days, the Texas Rangers finally have some company.

Jonny Gomes smacked a solo homer for Oakland, which clinched a postseason berth with a victory over the Rangers on Monday.

The A's, who are atop the AL West standings for the first time since March 29, can take the division in a winner-take-all showdown against the Rangers on Wednesday. Oakland shared first place with the Mariners at 1-1 after it beat Seattle in Tokyo.
Travis Blackley (6-4) fanned five and surrendered a run on three hits and two walks over six innings to notch the victory.

Gomes cracked a two-out solo shot into the left-field seats in the sixth to make it 3-1.
