The Portland Sea Dogs entered Friday’s home game with a two-game win streak for just the ninth time this season.

The good times did not last.

One day after Portland starter Justin Haley had pitched seven scoreless innings, Danny Rosenbaum gave up eight runs, was pulled in the third inning, and the Akron RubberDucks rolled to a 12-2 win in front of 6,906 fans at Hadlock Field.

Rosenbaum, 27, is coming back from Tommy John surgery performed in May 2014. He was with the Washington Nationals’ Triple-A affiliate Syracuse when he tore his ulnar collateral ligament. Dealt to the Red Sox in January for catcher Dan Butler, Rosenbaum has not gone more than five innings in 11 starts for Lowell and Portland and is 0-5 with a 7.04 ERA as a Sea Dog.

“The fact that he’s getting out there every fifth day is a positive,” Sea Dogs Manager Billy McMillan said. “Getting his pitch count back up, getting into the flow of competing. We would like the results to be positive but I just think collectively today was just not a great day for us.”

Rosenbaum allowed an unearned run in the first and worked a 1-2-3 second. His own wildness led to Akron’s seven-run third inning.

Rosenbaum walked the first two Akron batters, then fielded a sacrifice bunt and threw high and wide to first to load the bases. Shortstop Tzu-Wei Lin committed the Sea Dogs’ third error of the game when he bobbled a grounder, scoring one.

Bradley Zimmer followed with a two-run single – the first hit Rosenbaum allowed – to make it 4-1.

After an out, Rosenbaum was touched for a 405-foot three-run homer over the left field wall by Ronny Rodriguez.

Todd Hankins followed with a wall-ball double to end the night for Rosenbaum.

“Tonight was just a difficult night all around,” McMillan said. “We don’t normally make three errors. We don’t normally walk six guys collectively. (Rosenbaum) was just a victim of that tonight.”

After Mike Augliera relieved Rosenbaum, Hankins stole third and scored on a sacrifice fly.

Making his sixth relief appearance, Augliera worked 42/3 innings, allowing three runs, all via the long ball. Yandy Diaz hit a two-run homer in the fourth and Bryson Myles led off the sixth with a solo shot. Rodriguez homered in the ninth off Simon Mercedes.

Akron right-hander Duke Von Schamann, the son of former Oklahoma and Miami Dolphins placekicker Uwe von Schamann, was making his first start of the season. He worked five innings for the win, allowing two runs on four hits, including Carlos Asuage’s fifth home run. Von Schamann struck out the final four batters he faced.

Von Schamann, activated Friday, received a 50-game suspension prior to the 2015 season following a second violation of MLB’s minor league drug policy. In 2014, von Schamann was 8-8 with a 4.20 ERA for the RubberDucks and made two starts with Triple-A Columbus.

Portland (43-76) and Akron (64-55) play the second of three games at 6 p.m. Saturday.
