First Pitch: One Mo month

NEW YORK -- One month.

That’s how long the New York Yankees have to try and extend Mariano Rivera's career.

Today is Sept. 1, which means the rosters will expand, which means some young players will get their first big-league experience.

Rivera, 43, has already had plenty of big-league experience: 19 years in all.

But if the Yankees don’t make the playoffs, there will be no more Mo.

With 27 games remaining in the regular season, the Yankees find themselves 7.5 games back in the A.L. East and 3.5 games back in the wild-card race.

They’re going to have to play really well and receive some help in order to move on to October.

Colleague Andrew Marchand recently did a blog figuring the Yankees would probably have to go 21-8 the rest of the way to have a shot. That was two games ago. Make it 19-8 now.

Rivera is having an excellent season, racking up 39 saves while pitching to a 2.16 ERA.

The best closer of all-time is going to go out on top of his craft -- regardless of where the Yankees finish in the standings.

If you do get the chance to attend a game and hear “Enter Sandman” at the Stadium this month, soak it in.

Because this it is.
