It looks like the ax is going to fall pretty soon on a second manager.

A source has informed’s Buster Olney that the Baltimore Orioles will relieve manager Dave Trembley of his duties any day now. The source also informed Olney that third base coach Juan Samuel will take over when Trembley is let go.

Trembley took over for Sam Perlozzo in the middle of the 2007 season and is 187 and 282 in his four years as Orioles manager. That is a winning percentage of .399.

If you look at Trembley’s tenure in Baltimore, the Orioles have gotten worse every year under his stewardship. Here are Trembley’s winning percentage’s year by year:

2007: .430

2008: .422

2009: .395

2010: .283

In all fairness to Trembley, the Orioles haven’t had the best talent roster while he has been there, but 2010 was supposed to be the year where the Orioles turned the corner. Unfortunately for Trembley, the Orioles have gone severely backwards this year, and it will cost him his job.

Adam Jones has a .271 OBP, Matt Wieters is hitting .240, and Nolan Reimold was sent to the minors. These are the players the Orioles were planning on building around, and all have taken a step back this year. That is on Trembley.

The Orioles have an off day on the seventh. That is when I think president of baseball operations, Andy MacPhail, will let Trembley go.
