They currently hold a record of 13-8. This will not last—they don't have the ability to do it.
Their entire starting lineup basically consists of rookies with the lone exception of Luis Gonzalez. And Gonzo isn't even playing his normal position. He's playing right field—a position he has never played, not once in his entire 18-year career.
The Marlins are just not that good. Their success is due in part to the likes of Hanley Ramirez and Dan Uggla, but most importantly, it is due to sheer luck and lack of opposing talent.
However, the Marlins' downfall will be their pitching.
The Marlins No. 1 pitcher is Mark Hendrickson. You may ask yourself, "Who is this guy?" I could not agree more with your doubt.
Hendrickson is a 34-year-old journeyman who has played for six different teams in the last six seasons. His career ERA is 4.97. He has a career 47-56 record.
This is the guy you’re relying on to break you out of a losing streak? To win you that important game?
He's a joke.
Now onto the No. 2 starter Scott Olsen. He's in his third full year, and he's already considered the "ace" (I use the term very loosely).
In his previous two years he had ERAs of 4.04 and 5.81. Last year he went 10-15, and the year before 12-10. These stats are nothing but ugly.
Most of the Marlins pitchers are rookies—they will burn out from overuse before the season even comes to a close.
I guarantee that before the All-Star break the Marlins will be sitting at the cellar of the NL East, and possibly the National League
