Oakland Athletics First-Place Clinch Scenario

Oakland's traditional magic number (relative to first-place Houston) is 65 + 54 - 61 + 1 = 59.
Oakland's first-place clinch number is 53.

If Oakland wins 53 more games, their final win total will be at least 114.
The table below shows the best case scenario for each of the other teams if Oakland wins all 53 of their remaining games.
For each team, the table shows the current record (number of wins (W) and losses (L)) and the number of games that team has
left to play (GL) in the regular season. Taking the schedule of games left to play into account, the 'Losses to Oakland' column gives the
minimum number of games that each team will lose to Oakland if Oakland wins 53 more games. Assuming that a team wins all of its remaining games except for
the games it loses to Oakland, the resulting maximum number of wins and maximum winning percentage are shown in the 'Maximum W' column.

Team             W	L	GL	Losses to Oakland	Maximum W
Houston          65	43	54	       6 - 0 = 6	113
Los Angeles      54	54	54	       3 - 0 = 3	105
Seattle          58	51	53	       9 - 0 = 9	102
Texas            39	69	54	       9 - 0 = 9	84

The table above shows that if Oakland wins 53 more games (114 total), then they will finish the season in first place in the division.

To see that Oakland's first-place clinch number cannot be less than 53, consider the following scenario in which Oakland wins 52 more games (113 total) but does not finish in first place.

To construct the scenario, we start with the current standings in the division:
Team             W	L	GL	PCT	GB
Houston          65	43	54	0.602	0.0
Oakland          61	48	53	0.560	4.5
Seattle          58	51	53	0.532	7.5
Los Angeles      54	54	54	0.500	11.0
Texas            39	69	54	0.361	26.0

Next, we show how the remaining series of games in Oakland's division plays out in the scenario:

Houston wins 10 games against Los Angeles and loses 0.
Houston wins 0 games against Oakland and loses 6.
Houston wins 9 games against Seattle and loses 0.
Houston wins 7 games against Texas and loses 0.
Houston wins 22 games against teams outside the division and loses 0.

Texas wins 0 games against Los Angeles and loses 8.
Texas wins 0 games against Oakland and loses 9.
Texas wins 0 games against Seattle and loses 6.
Texas wins 24 games against teams outside the division and loses 0.

Combining the current standings with the wins and losses from the scenario results in the following final standings:
TEAM             W	L	GL	PCT
Houston          113	49	0.698	0.0
Oakland          113	49	0.698	0.0
Los Angeles      95	67	0.586	18.0
