CALEDONIA — Jantsen Glasgow didn’t know the game was over.

After a three-run double in the third inning, Glasgow called time and was in the process of taking his shinguard and batting gloves of so he could give them to the first base coach. That’s when he realized the game was over.

Glasgow’s bases clearing extra base hit proved to be the walk-off hit that propelled the Caledonia High School baseball team to an 18-3, three-inning win over Raymond High School for advancement in the Mississippi High School Activities Association Class 4A baseball playoffs.

“I didn’t think it was going to score all three,” Glasgow said. “I was thinking double all the way because I saw him go all the way to the fence.”

The Confederates (19-10) beat the Rangers (9-14) 7-0 Friday night to open the best-of-three series. Caledonia will play Amory, who swept New Albany, in the second round.

Leading 15-3 with the bases loaded and two outs, Glasgow was just trying to put the ball in play to pad the already big lead. Raymond pitcher Chavalier Dorris entered two batters previous and got a flyout before issuing a walk.

Dorris wasn’t throwing particularly hard, but Glasgow had to focus in and not get out in front of the pitch.

“I was trying to make good contact with the ball,” Glasgow said. “It just tried to wait back on it as much as I could.”

Glasgow hit a line drive over the third baseman’s head and the ball rolled to the fence. Caledonia coach John Wilson summed it nicely with: “He just mashed it.”

Sawyer Brown, Jarred Reed-Wood and Beau Bates all came home on the double to send the Confederates to the next round.

Caledonia took a commanding 10-0 lead after the first inning. The Confederates were walked seven times, including four in a row. They also got a three-run double from Bates and two two-run doubles from Seth Brown and Jordan Hollowell.

Although Wilson didn’t go into depth, he said he recently changed the approach of the offense to make the opposing pitcher throw more pitches. He said the first inning was a perfect example.

It’s helped give the his batters confidence.

“It’s been working out pretty well,” Wilson said. “We switched to it about 15 games ago and our team batting average at that time was .237, our team batting average right now is .294, so it’s worked for us.”

Glasgow said he has seen the new approach help and agreed with Wilson that the first inning was proof. Wilson said his team is taking advantage of good pitches in good counts because of the approach.

Caledonia added two more runs in the second and finished with six in the third. Starting pitcher Zach O’Neal had an RBI triple in the third to score Hollowell who reached on an error.

The Rangers tried to mount a comeback with three runs in the third. Trey Clark stole home on a pull-back sacrifice bunt attempt.

O’Neal loaded the bases with no outs to begin the third, but got two quick strikeouts to be one out away from getting out of the jam. He made Chandler Tinsley put the ball in play but third baseman Logan Suggs’ throw to first was off and two runs scored. O’Neal walked the next batter but threw out Eugene Lindsey from his butt to retire the side.

“He located really well, kept his pitch count down, threw real good strikes, just simple stuff like that,” Glasgow said.

The senior left-hander allowed two hits and recorded two strikeouts. O’Neal also had a double and a triple at the plate, for the only Confederate with multiple hits.

As Glasgow hustled to second base, he was beginning to think about what his assignment was from there and how he was going to score with two outs. But when he realized his hit just won the ballgame, he took a big sigh of relief.

“It was just pure happiness that we made it to the second round,” Glasgow said. “I’m happy for all these guys. Everybody’s contributed a lot this year.”
