DAYTON — Dan Jensen had to leave only seven tickets at will call for family and friends for the Dayton Dragons’ season opener. Some of his friends chose to watch the Reds on Opening Day.

But the Centerville High School graduate expects to get plenty of requests for tickets as the season progresses. His mom and dad and five friends watched him make history Thursday.

The 6-foot-7 reliever threw one scoreless inning in Dayton’s 3-0 victory over West Michigan at Fifth Third Field, becoming the first Montgomery County native to pitch for the Dragons.

Jensen struck out the first batter he faced, then allowed a single and a walk. With two outs, both runners advanced to third on a wild pitch, but Jensen struck out Colin Kaline, the grandson of Detroit Tigers Hall of Famer Al Kaline, to get out of the jam.

“I was a little nervous at first, obviously,” Jensen said. “It was good to get that one out of the way. I had played on this field before, but never pitched here before. It was really exciting.”

Thievery: The Dragons wasted no time showing off their speed, a season after leading all of professional baseball with 228 stolen bases.

Theo Bowe, who stole 20 bases last season in Dayton, walked to lead off the first and stole second. Bowe stole another base in the seventh, putting him well on his way to his season goal of 50.

“Theo’s going to be huge for us,” Dragons manager Delino DeShields said. “While he’s here, that’s what we expect him to do: be on base, cause some havoc and score some runs — Jefry Sierra as well.”

Closing the door: Ryan Kemp got the save by throwing scoreless eighth and ninth innings. West Michigan got the tying run to the plate in the ninth, but Kemp got a ground out to end it.

Another opener: After more than two decades in professional baseball, 13 as a player in the big leagues, DeShields doesn’t get butterflies anymore.

“I don’t know if they’re butterflies. They’re a different sort of flies,” the second-year Dragons manager said. “I’m just excited for the kids more than anything. We can talk about it all day, but they have no idea what they’re going to see out here the next few days.”

Tonight’s game: Radhames Quezada starts for the Dragons at 7 p.m. today, opposing West Michigan’s Tommy Collier. Quezada was 2-3 with a 3.83 ERA in 10 starts last season in Billings.

“He’s a Dominican kid,” DeShields said. “This is his first time in these elements. He’s got a bad nail he’s been battling through spring training, but I think he’ll throw well.”
