Here were his gamelogs for his wins in 2010:
1: 6.2, 2 ER
2: 7.0, 3 ER
3: 7.0, 1 ER
4: 6.0, 6 ER
5: 6.1, 2 ER
6: 6.0, 4 ER
7: 7.0, 2 ER
8: 6.0, 3 ER
9: 7.0, 1 ER
10: 7.1, 2 ER
11: 7.0, 5 ER
12: 8.0, 2 ER
13: 7.0, 1 ER
14: 7.2, 2 ER
Now, if you ask me, anytime you allow 4 ER or more, it's at least somewhat of a lucky win. So, I can see how you would say that 3 of his wins were lucky.
But, looking deeper into it, here are some of his other starts.
8 IP, 0 ER, No Decision
6 IP, 0 ER, No Decision
7 IP, 1 ER, Loss
6 IP, 2 ER, No Decision
7 IP, 2 ER, No Decision
7 IP, 2 ER, No Decision
So, it evens out, maybe he was due another 1-2 wins even than he got, but for the most part, it evens out. He certainly shouldn't have taken a ND against the Mariners in 2010 when he threw 8 IP, 0 ER.
But, sometimes our memory deceives us, I know mine often does, so I just wanted to provide some clarity.
