I bet on the Hamilton Tiger Cats yesterday in the CFL. Most people here probably don't follow the CFL but being Canadian, I do. Anyway, Hamilton was 4-5 on the Road. Toronto was 4-5 at Home. The bookies didn't give Hamilton much respect, so the odds were good for me to win. Hamilton paid 2.60 x my bet on a coin flip. Even odds are 1.91 / 1.91 where I bet.
La Russa made Eckersley his closer, and he developed the "MLB sapien" system that was choreographed to use the role sparingly. The engineering marvel put little to no stress on the pitchers arm in a single outing.  Thus resulting in that arm being used in consecutive games. Eckersley went on to establish records for relievers with a 0.61 ERA in 1990, and did what most thought was impossible then, and in truth now, by earning the American League Cy Young and MVP awards when he saved 51 games in 1992.
ATS equals “against the spread”. The spread is the number oddsmakers use to give people other betting options besides only wins and losses. A spread for a Premier League fixture would be something like .5 or 1.5. One club would need to lose the match by no more than 1 or 2 goals or the other needs to win by 1, 2or more goals.  If the final score doesn’t reflect the number set by the oddsmakers, your bet won’t cover the spread and you can’t win your bet.
