Mission accomplished in Operation Desert Broom. Either the Mets have begun getting their act together or the Diamondbacks are a complete farce of a baseball team. Whichever the case, the Mets have decided they will keep the wins. On Wednesday, they used seven shutout innings from Dillon Gee to complete a three-game sweep of these dead snakes with a 5-2 victory in front of 19,673 at Chase Field. Gee retired the first 14 batters he faced and didn’t allow a runner past second base in rolling to his first victory of the season. For a change Gee didn’t wilt late in the game, and for the first time in four starts pitched a scoreless frame in his final inning of work. But Gee was tested in the seventh, after Paul Goldschmidt doubled. The next batter, Miguel Montero, hit a shot to deep right that Andrew Brown caught near the top of the fence before Mark Trumbo was retired. “I’ve got to go out and prove and keep proving I can go deep into the game and maybe I’ll get that leash back,” said Gee, who was removed after 72 pitches. “There’s only one person to blame for me coming out that early, and that’s myself.” Manager Terry Collins indicated Gee started to get the ball up in the strike zone in the seventh inning. “They hit the ball hard to third, hit the ball hard to center, hit the ball hard to right,” Collins said. “I just said, ‘Our guys have been pitching good out of the bullpen. Let’s just get out of this road trip and go home.’ ”
