Had it been another afternoon, Joe Dee Tarbutton might still be kicking himself for the mistake.

Lawrence High’s softball coach got in a hurry filling out his lineup card before Thursday afternoon’s home game against Shawnee Mission East, and in his haste forgot to put sophomore Annie Grammer in one of her usual slots, at the top of the order — anywhere from second to fifth.

Luckily for the coach, he remembered to pencil her in at No. 7 in the lineup. Grammer responded by blasting a three-run home run in the second inning, one of many offensive highlights for the Lions in a 16-1, four-inning rout.

Tarbutton told Grammer, who went 2-for-3 with four RBIs near the bottom of the order, about the mishap before he posted the lineup in the dugout. The goodhearted sophomore didn’t even give her coach a hard time about it.

“I should’ve,” she said after Lawrence (8-7) won for the fifth time in its last seven games.

Obviously it worked out fine for all involved. After LHS put three runs on the board in the first inning, behind Jolona Shield’s double and Brook Sumonja’s triple, the floodgates opened in the second. Grammer’s shot just inside the left-field foul pole capped a seven-run inning and put the Lancers in a 10-0 hole.

“I thought it was about time,” Grammer said of her first homer of the season. “I kept hitting it to center field and it wouldn’t go over.”

No frustrations existed for the Lions on this afternoon. They ripped 17 hits, six for extra bases, and all nine LHS batters had at least one hit.

A senior, Shield went 3-for-3 and drove a runner or two home each time she put the ball in play, on her way to four RBIs.

“It feels good,” Shield said of winning easily and getting everyone involved. “It brings up our confidence a lot — all of us hitting like that. It really goes into the next game.”

Senior Morgan Byrn smacked two-run doubles in both the third and fourth innings, including the game-clincher, and finished 3-for-4 with five RBIs. Junior Sumonja, Grammer, freshman Zoe Brewer and senior Kenzie Garvin all finished with two hits.

The Lions, Tarbutton said, knew they were better than SME, so they came out confident and relaxed. He wants them to enter every game in that fashion, because doing so will take them far.

“You can see a little bit of a difference in our kids,” the coach said after the blowout. “I told them to quit coming to the field scared.”

The Lions and their coach all left the diamond impressed with the varsity pitching debut of Brewer. The freshman pitched four innings, allowed five hits, struck out four and walked two, while working with freshman catcher Abby Murrish.

Brewer loaded the bases with no outs in the second inning and got out of the jam by striking out three Lancers in a row. In the fourth, SME loaded the bases with no outs again, and the freshman held the visitors to one run.

With one out in the fourth, Garvin saved at least a couple of runs in center field by sprinting down a line drive to the left-field gap.

In Grammer’s eyes, that might have been the most impressive play of the afternoon.

“Your heart was racing a little bit since the bases were loaded,” Grammer said, “and then when she did that it was kind of like a relief.”

East’s threat died when Brewer snagged a waist-high line drive that came whizzing back at her.

Said Shield: “That was a pretty awesome catch.”

Lawrence’s second game, against Shawnee Mission West, was postponed due to inclement weather.
