Walter threw a complete-game six-hitter.
Next, with the bases loaded and one out in the bottom of the sixth, Lane let Mike Cudwadie hit after having two poor at-bats.
Cudwadie delivered a game-winning two-run single to left to lead Limeport to a 3-2 victory at Limeport Stadium.
The best-of-five series is tied at 2, with the deciding game at 5:45 p.m. Monday at Gabelsville.
"No one gives up, there's no quit," Cudwadie said of the Bulls, who have rallied from a 2-0 series deficit. "We were two innings away from a series lead [in Game 1] and our defense let us down in the second game. We played good defense [Saturday night], Ryan pitched a great game.
"We just needed our offense to get going. I was fortunate to get a good pitch to hit after missing twice at trying to bunt. I was lucky that the infield was in and the ball got through."
Ben Swatsky and pinch runner Devon Ziegenfuss scored on Cudwadie hit to left, which came against Gabelsville reliever Todd Stapleton.
Cudwadie's two previous at-bats came against Shawn Betz, who started on just two days rest. He was solid until the sixth, when Swatsky's bloop single to center, Tyler Lehman's single to right and Justin Godusky's fielder's choice [in which no outs were recorded] loaded the bases and chased Betz.
"I was glad to see [Cudwadie] not have to face Betz again," Lane admitted.
With the lead in the seventh, Walter, who has been rehabbing his left shoulder since surgery sidelined him, had plenty left in the tank. He allowed only an infield single to Josh Martin, who had three hits.
Walter gave up just two runs on six hits.
"I've been throwing on the side the last couple of weeks with my dad," Walter said. "My legs were getting stiff. For some reason, they were shaking. I was nervous, for sure.
"Once we got the lead, that gave me a big boost to [go out for] the seventh inning."
Each team scored a run in the second inning.
Dan Pierce walked for Gabelsville, took second on Mike Schweger's sacrifice bunt and continued to third on a throwing error on the play. Pierce scored on Brett Umstead's double-play grounder that was started by Lane's nice diving play at second.
Limeport tied it in the bottom of the inning when Lehman singled, took third on Justin Godusky's single and scored on Adam Ganser's grounder.
Gabelsville took a 2-1 lead in the fifth when Martin reached on a bunt single, was sacrificed by Ryan Zakszeski, took third on Betz's walk and scored on a wild pitch.
But Walter settled down. He retired seven of the last eight hitters he faced.
"I feel good now," Walter said afterward. "We'll see how I am tomorrow."
