Miami (AP) -- Maybe manager Mike Redmond wasn't the Marlins' problem.
Their final 22 batters went hitless, demoted closer Steve Cishek had another rocky outing and Miami lost to Arizona 3-2 in 13 innings Monday night, spoiling Dan Jennings' debut as manager.
Jennings gave up his job as general manager to move into the dugout and replace Redmond, who was fired Sunday. The Marlins lost their fourth game in a row, and seventh in eight games, but Jennings tried to put a positive spin on the latest defeat.
''There's a lot of good to take away,'' he said. ''There's a great energy in the clubhouse and dugout. We just came up a little short.''
The Marlins totaled six hits, the last of which was rookie J.T. Realmuto's first career homer, a two-run shot with none out in the seventh. The lack of offense had Jennings working overtime on his first day as a manager.
''It was surreal to be there in the moment,'' he said. ''It definitely moves quicker in the dugout than it does in the suite upstairs.''
Like Miami, Arizona had been scuffling until David Peralta hit a two-out RBI double in the 13th inning off Cishek (1-4). The Diamondbacks broke a four-game losing streak.
