​Dayton reliever Graham Osman played the underappreciated middle reliever role to perfection Saturday, Aug. 8, to change the momentum of a series against first-place Great Lakes.And who could have seen it coming. Osman pitched at Great Lakes on July 9 and allowed three runs in 1⅓ innings. He allowed a run in 1⅓ innings against the Loons on Tuesday, Aug. 4. He entered Saturday’s game in the fourth inning with a 9.00 ERA.The Loons already had five runs. They are in first place with a potent lineup. Surely, they weren’t finished.But after a 30-minute weather delay, Osman took the mound by storm and the Loons’ offense dried up. He pitched 3⅔ innings and struck out seven, including the side twice, to help lead the Dragons to an 8-5 victory.No hits, no walks, no runs, not even a base runner.“I was just focused on the job I had to do,” Osman said. “We had the delay, and I was told I was going to come out of the pen once we got started again. I was just trying to give us a chance to keep the lead and win the game.”Outings like Osman’s make managers happy and their job easier when a middle-man can be an uncompromised bridge from the early innings to the late innings.“It’s his best outing of the year,” Julio Morillo said. “To go out there and do what he did was unbelievable. And I think John Mike (Faile) did a really good job guiding him as well.”The first-half champion Dragons (57-48, 18-21 second half), as they attempt to mold a new lineup and settle in with some new pitchers, could use a lot more of what Osman (2-1) gave them. Jimmy Romano, who missed some time with an injury, is back and throwing well, too.Romano got the final out of seventh with a strikeout. A double and infield single started the Loons’ eighth. But shortstop Julio Carreras made a diving stop up the middle and flipped to second for a force out. Then, with a runner at third, Faile threw out Nico Perez (30 stolen bases) trying to steal second with a perfect throw.Romano got the next batter to fly out, and Trent Hodgdon pitched a perfect ninth for his eighth save, capping six scoreless innings from the bullpen.“A lot of good things have to happen to beat a team like them,” Morillo said. “We did those good things tonight.”Good things were needed after Great Lakes (57-46, 22-17) took a 5-0 lead in the top of the second inning against Stephen Quigley, a reliever who made his first start. Samuel Munoz and Emil Morales each hit a two-run homer. Morales has four homers in the series, seven this season against the Dragons and 16 since joining the Loons on May 19.But Quigley bounced back and pitched a 1-2-3 third inning before turning the game over to Osman.The good things for the Dragons began in the bottom of the second.Ty Doucette, 0-for-10 in his brief time in Dayton, hit a two-run homer to wake up the home dugout. Then Eric Becker, the highly rated prospect who joined the Dragons this week, hit his first professional home run, a three-run shot to the
