GLADSTONE — The Gladstone Indians made it a clean sweep this weekend, winning all three of their baseball games against a pair of Petoskey teams.

Gladstone mercied Petoskey A 12-2 in five innings here Saturday night after squeezing past Petoskey AA 4-3 in eight in non-league Under-19 contests.

The Indians (11-5) wasted little time taking charge in the nightcap, sending 11 hitters to the plate and scoring six times in the opening frame of their regular-season finale.

Zach Hanson scored the game’s first run on a botched pick-off. Dan Martin then gave the Indians a two-run cushion on Parker Frappier’s single to centerfield.

The Indians, who also edged the Royals’ A team by a run Friday night, took advantage of two errors, a walk and a hit batsman and Ian Schwalbach added a two-run double to left in the first inning of Saturday’s game.

“The biggest difference is we came out with a lot of energy and jumped on them right away,” said Indians’ manager Justin Jurek. “The guys came out swinging. In the first game, we came out a little lackadaisical. They brought up a quality team, but it’s a long weekend. It’s nice playing quality competition right before a tournament.”

The Indians made it 7-0 on Parker Frappier’s sacrifice fly to center in the second before adding five unearned runs in the fourth.

Gladstone batted around in the fourth while taking advantage of two errors, two walks, another hit batsman and a wild pitch.

“We had too many errors and ran out of pitching,” said Petoskey manager Kevin Horn. “Although, they hit the ball. They found the holes and we didn’t have an answer. We have a young team and a lot of sore arms right now.”

Tom Reid’s double to right got the Royals (9-9) on the board in the fourth and Nolan Spedefore drove in their second run on a single to center in the fifth.

Martin finished with two of Gladstone’s seven hits. Spedefore had a pair for Petoskey, including a leadoff bunt single along the third-baseline. The Royals had six hits.

“That was a real nice bunt by Nolan,” said Horn. “He executed that perfectly.”

Riley Baldovski earned the complete-game victory, striking out three and walking two.

Spedefore worked the first two frames and took the loss. He walked two, hit a batter and surrendered seven runs on six hits. Kaden Rice then allowed five runs on one hit in two innings of relief. He fanned three, walked three and hit a batter.

The Indians enter the Upper Peninsula tournament at Iron Mountain Thursday, opening against the host team at 3:30 p.m. (EDT).

“That will be a good tournament,” said Jurek. “There’s a lot of good teams this year.”

In other games at Gladstone Saturday, Menominee (20-3) outlasted Petoskey AA 4-2 in eight innings and scored seven times in the sixth inning of a 9-2 conquest of Petoskey A.

Menominee hosts Escanaba Tuesday.
