A +1.5 spread is commonly seen in baseball betting, the standard runline  for MLB. This spread means the underdog must win outright or lose by exactly one run to cover the spread. Alternatively, a -1.5 spread means that the favorite must win by at least two runs. Many baseball games are decided by fewer than two runs.

To do so, click on the System  tab at the top of the bet slip. The number of possible system bets depends on the number of predicted outcomes.

Select your bet type: Single, Multi or System. Enter the stake you wish to wager on your selected bets. Tap the Place bet  button (if your selections are correct) to submit your betslip. The confirmation page will be displayed upon successful processing.
