In a low-scoring championship match, Norway’s Tore Torgersen dethroned defending champion Mika Koivuniemi on Friday to win the 2019 Suncoast PBA Senior U.S. Open.

Torgersen, who will not be credited with a PBA50 Tour as he is a non-PBA member, defeated Koivuniemi, 184-178, at Suncoast in Las Vegas to claim the $15,000 top prize.

The championship match featured just seven strikes between the two players with neither of them connecting for a double.

Koivuniemi, who finished the match first, left a five pin on his first shot in the 10^th frame and struck on the fill, forcing Torgersen to just mark to secure the victory. Torgersen left and converted a nine pin to get the job done.

In the semifinal, Torgersen advanced with a tough 196-180 victory over Norm Duke.

The match was within a mark almost the entire way. Torgersen finished first and needed nine, spare, strike for the shutout. He struck on his first shot and then converted a spare to lock up the win.

Duke, who has made the stepladder in every PBA50 event in which he has bowled this season, only threw three strikes in the match and left a devastating 6-7-10 for an open in the eighth frame.

Duke moved into the semifinal with a blowout 243-195 win over Rolando Sebelen.

Duke actually started the match by falling behind with a 7-10 split in the first frame, but he rattled off seven strikes in a row starting in the third frame to pull away. Sebelen, meanwhile, never threw a double but was clean throughout the game.

In the opening match of the stepladder, Sebelen built a big early lead and rolled to a 246-200 win over non-member Steve Smith.

Sebelen struck on six of his first seven shots, the only non-strike coming in the second frame when he left and converted a 10 pin. Smith missed a 10 pin to open the match and never recovered.

The PBA50 Tour takes a break until July 10 when the PBA50 River City Extreme Open begins live on FloBowling.
