The Miami Marlins had a bunch of interesting storylines going during tonight's game versus the Colorado Rockies. The major headline was the debut of Christian Yelich and Jake Marisnick, who were promoted after last night;s game. The other story was the first start of the second half by youngster Jose Fernandez, who is coming off a terrific All-Star appearance. Finally, it would be nice to see the Marlins get some more runs scored, especially coming from Giancarlo Stanton.

All of that happened and more in tonight's 4-2 win over the Rockies. Christian Yelich's debut was fantastic, as he notched three hits in four plate appearances, including two RBI singles that brought in crucial runs for the Marlins. Yelich started things off with a sharp grounder to the right field side on his second pitch in the majors. He continued in the third inning, when he lined his best-hit ball to right-center field, driving in Adeiny Hechavarria from second base. He topped off his spectacular night in the fifth inning with a third hit, driving in Jose Fernandez from third base on a hard-hit grounder that ate up the drawn-in D.J. LeMahieu.

Meanwhile, Jose Fernandez was just polishing up another terrific outing. He struck out eight batters on nine whiffs, five of them coming out of the strike zone. He also walked two batters and gave up a mammoth solo home run to Todd Helton, but he recovered from some tough spots and got key defensive plays. That included a double play by the middle infield, an outfield bomb from Stanton that caught Dexter Fowler, and Fernandez's pickoff that erased a runner.

Finally, Giancarlo Stanton got in on the act and had some fun as well, as he blasted his 11th home run of the season in the eighth inning to give the Marlins some insurance runs after Fernandez the score to get to 3-2 in the sixth inning.

If there was one disappointment on the night, it was that Jake Marisnick did not enjoy as successful a debut. He went 0-for-4 with three groundouts and a pop up to start his big league career. Nevertheless, the Marlins had to be happy with the youth on display tonight.
