I don't usually bet this prop, but BetUs had this at +140 for Yes, score in 1st inning. 5dimes only had it for +110, but I took a little action on both books.
I think St. Louis comes out hot, and Carpenter has allowed a run in the first inning 2 out of his last 3 starts. Somebody will score.
I was gonna bet big on no score 1st inning but I backed out right before gametime. Lucky me!!! I have been playing this prop usually once a day for the last 4 days and have been 4 out of 4. Today would have been my first loss, but I didn't place so it don't count! Woo hoo!!!
