Over/Under

Just when Jane, Korsak, and Frost go to practice for the baseball finals, Frost's mom, roommate, and roommate's son come to visit Frost. Then Maura and Jane are called into the case of a man who was stabbed in the throat in the middle of a car wash. They find that the murder victim was a former football star who lost his career when a player slipped and fell and now owns a bakery with all of his ex-girlfriends. Frost's mother confesses that she's getting remarried and doesn't know how to tell Frost. Maura and Jane argue over the medical staff playing with the homicide squad during the baseball finals. During the victory dinner for the medical squad, Frost confesses that he always knew that his mother and her roommate were partners and knew she would tell him if she wanted to. Jane and Korsak find that the football game that ruined the victim's career was rigged, that the same thing happened the day he died, and that's the reason he was killed. They find that the friend he went to was actually the man that was rigging the games, so that he could win money due to the Over/Under rule. Casey comes back and tells Jane that he's going to get surgery on his spine and doesn't want her to worry, but Maura shows Jane all of the statistics behind Casey's surgery so Jane will know that he might not make it.
