The Bonney Lake and Sumner High baseball teams advanced to the state’s Sweet 16 but each found the competition too tough during the regional round of state play.

The Sumner Spartans, competing at the Class 4A level, traveled Saturday to Heritage Park in Puyallup for the opening round of the single-elimination tournament. After keeping their hopes alive with an 8-3 victory over Lake Stevens, the Spartans had their season halted with a 9-5 loss to Kentlake.

Advancing to the 4A’s Final Four were Kentlake, Kentwood, Puyallup and Skyview. They will battle in a pair of Friday games at Safeco Field in Seattle. Friday’s winners will take the field Saturday, again at Safeco, for the Class 4A championship.

Bonney Lake had a longer trip – competing at Bannerwood Park in Bellevue – but found the same result.

The Class 3A Panthers notched an opening victory, beating Snohomish 8-1, but were eliminated due to a 12-4 loss to Mercer Island.

The 3A’s Final Four of Mercer Island, Southridge, Gig Harbor and Edmonds-Woodway will compete Friday at Safeco Field in Seattle. Friday’s winners will square off Saturday, again at Safeco, for the 3A crown.
