PHILADELPHIA -- Travis Jankowski got jammed and broke his bat on a 98.4 mph fastball.

But, somehow, he shot the ball up the first-base line in the first inning Friday at Citizens Bank Park. It rolled past Marlins first baseman Jesús Aguilar and into the outfield. The hit, which left Jankowski’s bat at just 64.9 mph, scored three runs to hand the Phillies a three-run lead in a 5-2 victory over the Marlins in Game 1 of a doubleheader.

The win moved the Phillies (45-44) over .500 for the first time since June 13.

“It’s a bit of a relief,” Jankowski said about his first-inning hit. “Off the bat, it’s one of those that doesn’t feel great. You’re kind of praying for something to happen.”

Jankowski’s single to left in the third scored the Phillies’ fourth run and set a career high with four RBIs. His bunt single in the sixth tied a career high with three hits.

Jankowski enjoyed the moment. He graduated from Lancaster Catholic High School in 2009, so he spent his formative years watching the Phillies win a World Series and dominate the National League. He came up with the Padres, and he called a brief conversation early in his career with Chase Utley at second base at Dodger Stadium one of the greatest thrills of his life.

Jankowski signed a Minor League contract with the Phillies in the offseason. He joined the Major League team at the end of May when it placed Roman Quinn on the injured list with a season-ending left Achilles injury. He went 0-for-2 in his Phillies debut in Cincinnati, then got picked off second base four days later in the ninth inning in a 2-1 loss to the Nationals.

But Jankowski is batting .350 with a .969 OPS in 40 at-bats. He has been a nice find.

“It’s been great,” Jankowski said. “Obviously, this is the team I rooted for growing up, so to be able to contribute and help the team win, it’s just one of those things that’s exhilarating. To walk into the clubhouse and the guys are all over you, it feels really good. It’s a great feeling.”

Jankowski has had plenty of support at home, too. He will get texts before and after games from friends and others from Lancaster saying they are coming to the game or attended the game.

It happens every day.

“A lot of the people from my hometown, this is their team, too,” he said.
