The Houston Astros have been hit with some serious accusations of sign-stealing which is huge no-no in baseball.

Now, this isn't the first time they've been accused of cheating, however this time it's getting traction.  This, week there has been several videos claiming to show the Astro sign-stealing during the 2017 season...that's the season they won the WORLD SERIES.

Apparently, they had a camera hidden in center-field zeroed in on the catchers fingers to steal the signs and alert the batter on what pitches were being thrown.

How did they let the batters know what pitch was coming?  Allegedly the video feed was relayed to the Astros' clubhouse and they would alert the batter with a series of bangs whether it was a fast ball or change up.

That's crazy, the batter only has seconds to supposedly interrupt the bangs as to what pitch is coming.

And now, new bombshell, pitcher Mike Fiers is saying the allegations are true. He was with the Astros in 2017 and said:

I just want the game to be cleaned up a little bit because there are guys who are losing their jobs because they're going in there not knowing.
