Why can’t things just be easy for the New York Mets?

The Mets lost on opening day. In extra innings. In a game that they held the lead in. Twice. In a game that they took a lead on league ace Stephen Strasburg.

Closer Bobby Parnell blew a 5-4 lead in the ninth after three pitchers combined to blow a 4-2 lead in the seventh.

And now Parnell could miss extended time after an MRI revealed a partial tear of the MCL in his throwing elbow. He was treated with a platelet-rich plasma injection and will take two weeks off before resuming a throwing program.

But, anything with the elbow is cause for concern, and Parnell could need surgery to repair the damage.

The Mets already lost ace Matt Harvey for the year (presumably) with an elbow injury.

General manager Sandy Alderson thinks the Mets could win 90 games this year. He’s that confident in the product he’s putting on the field. That can’t happen if guys can’t stay healthy. Especially key, key guys.

The Mets and their fans have suffered enough. They don’t deserve this.

Jose Valverde figures to assume the closing duties.
