Seattle Mariners First-Place Clinch Scenario

Seattle's traditional magic number (relative to first-place Houston) is 64 + 56 - 56 + 1 = 65.
Seattle's first-place clinch number is 56.

If Seattle wins 56 more games, their final win total will be at least 112.
The table below shows the best case scenario for each of the other teams if Seattle wins all 56 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 Seattle' column gives the
minimum number of games that each team will lose to Seattle if Seattle wins 56 more games. Assuming that a team wins all of its remaining games except for
the games it loses to Seattle, the resulting maximum number of wins and maximum winning percentage are shown in the 'Maximum W' column.

Team             W	L	GL	Losses to Seattle	Maximum W
Houston          64	42	56	       9 - 0 = 9	111
Oakland          60	47	55	       9 - 0 = 9	106
Los Angeles      52	53	57	       6 - 0 = 6	103
Texas            38	67	57	       6 - 0 = 6	89

The table above shows that if Seattle wins 56 more games (112 total), then they will finish the season in first place in the division.

To see that Seattle's first-place clinch number cannot be less than 56, consider the following scenario in which Seattle wins 55 more games (111 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          64	42	56	0.604	0.0
Oakland          60	47	55	0.561	4.5
Seattle          56	50	56	0.528	8.0
Los Angeles      52	53	57	0.495	11.5
Texas            38	67	57	0.362	25.5

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

Houston wins 10 games against Los Angeles and loses 0.
Houston wins 6 games against Oakland and loses 0.
Houston wins 0 games against Seattle and loses 9.
Houston wins 7 games against Texas and loses 0.
Houston wins 24 games against teams outside the division and loses 0.

Texas wins 2 games against Los Angeles and loses 9.
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          111	51	0.685	0.0
Seattle          111	51	0.685	0.0
