David Ortiz's Historically Great Season (so far) For A Guy 40+ Years Old

Using the Baseball Reference Play Index, here is the top 10 in OPS+ for qualifiers 40+ years old:

Rk	Player	OPS+	Year	Age
1	David Ortiz	188	2016	40
2	Willie Mays	158	1971	40
3	Edgar Martinez	141	2003	40
4	Dave Winfield	138	1992	40
5	Stan Musial	137	1962	41
6	Darrell Evans	135	1987	40
7	Cap Anson	135	1894	42
8	Carlton Fisk	134	1990	42
9	Ty Cobb	134	1927	40
10	Rickey Henderson	128	1999	40
11	Deacon White	128	1888	40

Okay, I did the top 11 since we don't know where Ortiz will end up. If Ortiz has an OPS+ of 110 the rest of the way, he would end up with 132, still in the top 10. If he can do 140 the rest of the way (140 was his OPS+ in each of the last two seasons) he would finish at 153, which would still be the 2nd best ever. If he does 148 the rest of the way, he finishes with 159 and that would still beat Mays.

If I use 300+ PAs as a qualifier, here are the leaders. Only Ted Williams is higher than what Ortiz has right now.

Rk	Player	OPS+	PA	Year	Age
1	Ted Williams	190	390	1960	41
2	Barry Bonds	169	477	2007	42
3	Willie Mays	158	537	1971	40
4	Barry Bonds	156	493	2006	41
5	Edgar Martinez	141	603	2003	40
6	Brian Downing	138	391	1992	41
7	Dave Winfield	138	670	1992	40
8	Moises Alou	137	360	2007	40
9	Stan Musial	137	505	1962	41
10	Harold Baines	136	486	1999	40
11	Carlton Fisk	136	419	1989	41
