For whatever reasons, Bloom seems to have been forced, at times, or chosen to not spend much on the rotation.
In 2020, he barely had anything to spend on any positions. His biggest signing was a SP'er though:
Martin Perez: $6M- not a horrible signing, and as it turned out, he became a pretty good SP'er the minute he left the Sox.
In 2021, Bloom's budget was limited, and he did spend a pretty good percent of the winter budget on the rotation, but trying to find 2-3 quality SP'ers on less than $20M is not something one should get high expectations over:
Richards $10M- did okay in the pen, but was a failure
MPerez II $5M- Had a 3.51 ERA after 11 starts but came unglued. Failure. Was very good for Texas in 2023.
I actually think Bloom did a fine job with his 2023 pitcher signings. The Story signing took a big chunk of the budget up, as did the JBJ trade, but he spent a good chunk on SP'ers and some on the pen. Again, what can be expected from spending $18M on 3 starters?
$7M Wacha- turned into a very good signing, despite time missed due to injury.
$6M Paxton- was made more for 2023, but looks like a failure.
$5M R Hill- another very good signing, for the money\
(Pen: Diekman and Strahm- a 50-50 choice.)
Bloom's best SP moves were from Rule 5 (Whitlock) and trades (Pivetta).
His 2023 choice:
$10M Kluber
(Pen adds: Jansen, Martin, JRod, Mills, Bleier)
I may be in the small minority that sees more promise with the rotation and the future outlook of our rotation than at any time since the start of the 2019 season.
Sale finally looks healthy.
Kluber looked like a better choice than Richards & Paxton.
Whitlock is under team control for several more years, thanks to Bloom.
Paxton is a pure dice roll.
Bello looks like the real deal, to me
Pivetta seems to be one of MLB's best 5th starters, but that only works, if we have 4 better than him, which I think we do, now.
Added to these 6 are some promising young pitchers and prospects. We may only need 1-2 to do well:
Houck should be in the pen, but he can be a decent 4-5 IP SP'er.
Crawford & Winckowski
Mata, Walter & Murphy
