Agreed.
I've argued for years that Pivetta is one of MLBs best #5s. The problem is, he's had to be out #3 for too long.
I've never been one to think stacking a team with #3's to 4's is a winning strategy, but if we add two solid SP's and make Bello our #3, I'm fine with having 4-5 guys with "3-4" profiles fighting for the 4-5 slots.
I know the whole numbering of slots bothers some, and out of those who don't mind the concept, there is a wide disparity on how to determine who is a #1, 2, 3, 4 and 5, but based on the 450 SP'ers who had more than 80 IP in a specific season from 2021 to 2023, here is how their fWARs broke down by slots.
3 seasons x 30 SP'ers (1 per team) = grouped by 90's and Split Seasons
#1: 3.3 to 7.5
#2: 2.1 to 3.3
#3: 1.3 to 2.1
#4: 0.6 to 1.3
#5: negative fWAR to 0.6
Thus is the state of MLB rotations, these days, on average.
Top Sox fWARs by SP'ers since 2021 (60+ IP)
#1 seasons: 2
5.7 Nate in '21
3.9 ERod in '21
#2's: 3
2.2 Pivetta in '21 (It's no wonder '21 was the year we did well.)
2.2 Crawford '23
2.1 Sale '23
#3's: 4
1.8 Hill '22
1.6 Bello '23
1.5 Wacha '22
1.5 Pivetta '22 (Note how Pivetta is the only repeat pitcher in the top 10.)
#4s: 5
1.0 Houck '23
1.0 Nate '22
1.0 Paxton '23
1.0 Pivetta '23 (3 seasons in the top 11 on the team)
0.6 Perez '21
#5's: too many to count
0.5 Richards '21
0.4 Crawford '22
0.0 Winck '22
So, in the last 3 seasons, we have seen these comparative performances:
2 number 1s
3 number 2s
4 number 3s
5 number 4s
3+ number 5s
Per season averages:
1 number 1 or 2
1 number 3
2 number 4s
1+ number 5s
We basically had an extra #4 and no #1.
