DAYTON — The winningest regular season in Dayton Dragons history had been over for about 10 minutes on Monday when Frank Pfister, the team’s elder statesman at age 25, made something abundantly clear.

With teammates gathered around him in a festive clubhouse, Pfister — a role player who on this day batted cleanup and drove in two runs in a 3-2 defeat of the Lansing Lugnuts — proclaimed at the top of his voice, “We’re not done!”

“That’s just something I’ve been saying the whole year,” Pfister said. “And there’s no reason to stop now.”

The Dragons open the Midwest League playoffs Wednesday at Fifth Third Field against the Lugnuts. If they can advance by beating Lansing twice, as they did over the weekend, they will have the home-field advantage in any subsequent series based on their league-best 83-57 record.

“It’s pretty exciting, being the young team that we are, to get into the playoffs,” shortstop Billy Hamilton said after stealing three bases to finish with 103 this season, the ninth-highest total in the history of minor league baseball. “We just need to keep playing the way we’ve been playing.”

Seemingly peaking at the perfect time, the Dragons have won 23 of their last 30 games. Monday’s success broke the franchise record for wins in a season, previously held by the 2001 team.

And when four pitchers combined to yield one earned run, the staff finished with an earned-run average of 3.39, bettering the club record of 3.41 set in 2007.

“Every one of those guys has the talent, and they just came out and proved it this year,” catcher Chris Berset said. “It’s no surprise.”

Chad Rogers gave up a run in the ninth, then ended the game with a strikeout, adding to the Dragons’ MWL single-season record in that category (1,292). Lansing’s first run had been unearned, thanks to a throwing error by starter Tanner Robles, who otherwise shackled the Lugnuts, striking out nine in five innings.

Pitching coach Tony Fossas, appropriately, was chosen to sign autographs in the Dragons’ team shop after the game. Usually that honor goes to a player.

“The pitchers did a real good job this year,” Fossas said. “They were good students and they got better as the year went on.”

The Dragons went 48-22 in the second half, best in franchise history and best among the 80 teams that play a split-season schedule. They set club records for wins in a month with 22 in August, road wins in a season (38), shutout wins (14) and, thanks mainly to Hamilton, stolen bases in a season (224).

Hamilton on Monday passed Vince Coleman (101 in 1984) and Donnell Nixon (102 in 1984) on the single-season minor-league steals list.

“I’m happy to see these kids improve,” manager Delino DeShields said. “That’s what brings me joy, to see them get things we’ve been talking to them about and do these things in a game. It makes me a happy man, a happy papa.”

At the beginning of his first season managing a team above rookie ball, DeShields said the Dragons would be exciting. He was right.

“I feel good about what we’ve done,” DeShields said, “but it starts with good talent. These guys have made me look good.”
