Pete Rose Bet While Playing

Not in absolute terms, but relatively, of course they can.

If Kershaw wants to throw a game and thus gives up 6 runs in 3 innings, his team will lose at least 90& of the time.

A manager obviously makes decisions that improve or hurt his teams chances of winning, but I would guess he only could only move the needle a few percentage points with his decisions.

Yep - that's the key:  While a manager or player might not be able to single-handedly throw a given game, they can change the odds from what they otherwise would be.  Over a number of games, it could make a difference.  Particularly handy in baseball, where you have 162 chances over the regular season.

Kind of the same as insider trading.  The inside knowledge you have might not always result in the stock price change you expect, but you are still working with an advantage not available to others.
