Los Angeles Dodgers First-Place Clinch Scenario

Los Angeles's traditional magic number (relative to second-place San Diego) is 14 + 135 - 15 + 1 = 135.
Los Angeles's first-place clinch number is 132.
Los Angeles must win 132 more games (147 total) to clinch first place.

If Los Angeles wins 132 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 Los Angeles wins 132 of their remaining 136 games and loses the other 4.
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 Los Angeles' column gives the
minimum number of games that each team will lose to Los Angeles if Los Angeles wins 132 more games. Assuming that a team wins all of its remaining games except for
the games it loses to LADodgers, the resulting maximum number of wins is shown in the 'Maximum W' column.

Team             W	L	GL	Losses to Los Angeles	Maximum W
San Diego        14	13	135	       8 - 4 = 4	145
San Francisco    12	14	136	      10 - 4 = 6	142
Arizona          12	14	136	      13 - 4 = 9	139
Colorado         6	19	137	      13 - 4 = 9	134

The table above shows that if Los Angeles wins 132 more games (147 total), then they will finish the season in first place in the division.

To see that Los Angeles's first-place clinch number cannot be less than 132, consider the following scenario in which Los Angeles wins 131 more games (146 total) but does not finish in first place:

Team             W	L	PCT	GB
San Diego        146	16	0.901	0.00
Los Angeles      146	16	0.901	0.00
San Francisco    89	73	0.549	57.00
Arizona          85	77	0.525	61.00
Colorado         65	97	0.401	81.00
