188, 215, 143 = 546 (170 Average)

1st game - Missed two 10 pins in the channel, moved 2 boards right on the approach and was 5 out of 6 the rest of the night on 10 pins.
2nd game - Clean game. Didn't connect any strikes until the 9th and 10th frame (finished with a 4 bagger).
3rd game - Four splits and one missed 10 pin spare doesn't add up to a good score.

Overall, it was a good night (even with that last game).
