Cleveland Indians First-Place Clinch Scenario

Cleveland's traditional magic number (relative to first-place Detroit) is 15 + 137 - 14 + 1 = 139.
Cleveland's first-place clinch number is 133.
Cleveland must win 133 more games (147 total) to clinch first place.

If Cleveland wins 133 more games, their final win total will be at least 147.
The table below shows the best case scenario for each of the other teams if Cleveland wins 133 of their remaining 138 games and loses the other 5.
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 Cleveland' column gives the
minimum number of games that each team will lose to Cleveland if Cleveland wins 133 more games. Assuming that a team wins all of its remaining games except for
the games it loses to Cleveland, the resulting maximum number of wins is shown in the 'Maximum W' column.

Team             W	L	GL	Losses to Cleveland	Maximum W
Kansas City      10	14	138	       7 - 5 = 2	146
Detroit          15	10	137	      13 - 5 = 8	144
Minnesota        9	15	138	      13 - 5 = 8	139
Chicago          5	19	138	      10 - 5 = 5	138

The table above shows that if Cleveland wins 133 more games (147 total), then they will finish the season in first place in the division.

To see that Cleveland's first-place clinch number cannot be less than 133, consider the following scenario in which Cleveland wins 132 more games (146 total) but does not finish in first place:

Team             W	L	PCT	GB
Kansas City      146	16	0.901	0.00
Cleveland        146	16	0.901	0.00
Minnesota        79	83	0.488	67.00
Chicago          78	84	0.481	68.00
Detroit          75	87	0.463	71.00
