Correct odds for Yankees/Rangers matchup?

Trying to put together an understanding of what to expect from the series. Here's the matchups I have with the odds I'm placing of a Yankees victory:

Game 1	Sabathia	Wilson	2/3
Game 2	Pettite	Lewis	1/2
Day off
Game 3	Hughes	Lee	1/10
Game 4	Sabathia	Hunter	4/5
Game 5	Burnett	Wilson	1/2
Day off
Game 6	Pettite	Lewis	1/2
Game 7	Sabathia	Lee	1/5

The end result for me is that this is much closer a series than any Yankee fan wants to admit, and that the rotations match up quite well. Home field advantage for the Rangers may even this up.

The chance of going 2-0 for the yYankees is 1/3, while the chance for the Rangers is 1/6. Putting the odds post Lee at

Yankees 3-0	2/60
Yankees 2-1	23/60
Rangers 2-1	26/60
Rangers 3-0	9/60

Look for the Rangers to have the lead after 3. Post game four though:

Yankees 4-0	8/300
Yankees 3-1	132/300
Tied 2-2	125/300
Rangers 3-1	26/300
Rangers 4-0	9/300

Yankees look in good shape. If the Rangers can win 2 out of the first three though, look out New York. Looking at 2-2 with an edge to the Rangers, and a 1/4 chance of winning it before Lee gets the hill again against a second three day rest for Sabathia.
