Everything has been going well on the baseball diamond for Huron High School senior Jalen Bouma.

On the other end of the spectrum is Pioneer junior Kailen McKay, who coach Jerry Holley called his "tough-luck kid."

But both played the role of seventh-inning hero in Saturday afternoon's doubleheader split at Pioneer.

McKay brought four hours of emotional rivalry baseball to a celabratory end for the Pioneers when he hit a walk-off, three-run home run for a 7-5 win. That evened the doubleheader after Huron's 5-2 win in the opener.

McKay didn't think he was ending the game when he connected on the full-count, two-out pitch from Huron reliever Ned Messmore and sent it over the left-field fence.

"I thought I just tapped it and thought it was going to be a base hit," McKay said. "I just looked over and saw it go over the fence, and I was like, 'Wow.'"

Holley said McKay, the Pioneers' No. 8 hitter who brought a .230 batting average into the game, was due for a big hit.

"He's hit seven or eight balls that have just been rockets right at people," Holley said. "He's been the hard-luck kid all year long."

In the first game, Bouma not only performed his late-inning heroics at the plate -- driving in the game-winning runs with a bases-loaded double in the top of the seventh inning -- but was able to put an exclamation point on the performance from the pitcher's mound.

He struck out the side in Pioneer's bottom of the seventh inning to complete his four-hit, complete-game win.

"It felt good. It's definitely good to beat Pioneer, especially senior year," Bouma said. "It would have been nice to get the second game and have everything tie together, but that's how it is."

Bouma is now 3-1 on the season and has allowed just nine hits in four starts. He was the tough-luck loser while throwing a three-hitter at Temperance Bedford earlier this season.

"Any time he comes up to the plate with guys on base, it's a good feeling as a coach. He's come through for us all year, and done a great job on the mound," said Huron coach Terry Bigham.

Bouma's nemisis on Saturday was Pioneer centerfielder Miles Sorise, who had three of the Pioneers' four hits. One was a solo home run in the third inning. He also doubled twice.

James Strickland drove in Sorise with his own double for Pioneer's other run.

The first game was tied 2-2 heading into the top of the seventh when Bouma exacted a little revenge on Sorise, sending a double over his head to the center field fence, scoring Andy Samaroy and Patrick Jobst.

Messmore scored on an insurance run on a fielder's choice off the bat of Ryan Nikischer.

Pioneer jumped out to a 2-0 lead in the first inning of the second game when courtesy runner Joey Johns scored on a throwing error and Strickland drove in Sorise with an RBI single.

That lead disappeared in the third inning, however, when Huron scored five runs on just two hits. The River Rats were aided by three Pioneer errors, two bases-loaded hit-by-pitches and a bases-loaded walk.

Johns took the mound in the fourth inning and allowed just two Huron hits the rest of the way to allow for the Pioneer comeback.

The Pioneers left two runners in scoring position in the fifth inning after a Travis Maezes RBI single, and then failed to score after loading the bases in the sixth.

But they were able to close the deal in the seventh, pulling within 5-4 on an A.J. Ross RBI single and winning the game with McKay's home run.

"It was a good ending to a good rivalry doubleheader," Holley said. "A good way to lead into the next round on June 1."

The teams play a Class A pre-district game at Dexter on June 1.
