The number seven was unlucky for the Vallejo Admirals on Thursday night at Arnold Field.

The Sonoma Stompers scored seven times in the second inning en route to an 8-4 win over the Admirals to conclude a three-game, Pacific Association series. Sonoma won the series two games to one.

The Admirals (4-5) put up two in the first inning against Stompers starting pitcher Mike Jackson Jr., the son of the former Giants reliever. Darian Sandford reached on a bunt single, Tim Williams singled and Pedro Perez walked to load the bases. Jackson Valera hit into a fielder’s choice but Sandford scored. Later in the inning, Wilfredo Petit singled home Williams.

The Stompers (6-3), however, played seven in the second inning against three Vallejo pitchers. Starter Tim Brechbuehler went one plus inning, allowing two runs while reliever Eric Kline could not retire a batter, allowing three hits and five runs. Wendell Floranus was finally able to end the inning and pitched three innings overall, allowing two hits and no runs.

Vallejo scored single runs in the fifth and sixth. In the fifth, Sandford reached on a fielder’s choice, stole second and scored on an errant throw from the pitcher. In the sixth, Lydell Moseby singled in Petit, who had singled himself.

Petit had two hits for the Admirals. Derrick Fox had two hits for the Stompers.

Jackson worked five innings, allowing five hits and all four runs. Reliever Eric Mozeika pitched four scoreless innings to conclude the game.

Note: After the Pacifics’ game on Friday, the Admirals will show the Randy Quaid movie “The Rookie” at Wilson Park. Concessions will stay open during the movie. First pitch is 6:30 on Friday.
