Zimmerman probably dreamed about finishing his high school career with a clinching strikeout or a winning hit in the state championship game.

The 6-foot, 215-pound senior, an ace southpaw and first baseman, made the latter a reality.

With the bases loaded and two outs in the 10th inning of Friday night’s PIAA Class 5 state final against Lower Dauphin, Zimmerman delivered a walk-off single to lift the Tigers to a 2-1 victory.

His clutch shot, which caromed off the bottom of the right-field wall, set off a celebration behind the mound at Penn State’s Medlar Field at Lubrano Park.

“I was going to do anything to put the bat on the ball and hit it hard,” Zimmerman said shortly after Marple Newtown clinched its first state title. “I wasn’t going to let my team down.”

The St. Joseph’s University recruit went 10-0 with a 0.75 ERA and 104 strikeouts in 74 2/3 innings. He yielded 46 hits and eight earned runs while walking 17.

“He’s a super competitor,” Marple Newtown coach Mark Jordan said. “He was a bulldog every time he took the mound.”

Zimmerman batted .469 with 38 RBIs, 25 runs, 10 doubles, seven home runs and two triples. He had a .901 slugging percentage and .500 on-base percentage.

The 17-year-old from Broomall went 5 2/3 innings against Lower Dauphin, holding the Falcons to one run while yielding six singles and striking out five.

Zimmerman, who was an undersized tackle in football, is expected to be a two-way player for St. Joseph’s. He plans to major in criminal justice in college.

“I’m excited to get started at St. Joe’s,” he said. “I like the coaching staff. The players get along well. The facilities are great, and it’s nice that the school is not too far from home.”
