GRAND JUNCTION, Colo. (KKCO)-- The Grand Junction Rockies have officially arrived, but they could not do it in winning fashion on Monday night.

The GJ Rox (COL) lost their first game in franchise history to the Ogden Raptors (LAD) by a score of 13-7.

Miguel de Leon did make sure the Rockies had something to celebrate in their first night of existence, though. De Leon crushed a three-run homer in the top of the fourth inning - the first homer in GJ Rockie history.

Poor defense and a lack of shutdown pitching contributed to the team's 0-1 start. The Rockies committed four errors on the night, while Brian Rike, Kyle Roliard and Patrick Johnson surrendered a combined six runs on five hits through the last 4.2 innings.

Alving Mejias will get the ball on Tuesday for game two in Ogden. First pitch is scheduled for 7:05pm.
