Pivetta through age 27: 406 IP, 5.40 ERA, 79 ERA+
Jake Arrieta through AGE 27: 409.2 IP, 5.23 ERA, 80 ERA+
Both pitchers were traded in July of their age 27 seasons.
Out of nowhere, Arrieta then put up the following number in his next 4 seasons: 751.1 IP, 2.67 ERA, 151 ERA+
Now expecting that kind of turnaround from Pivetta is certainly a bit much, but there are a lot of similarities between the two, and Arrieta has certainly shown that it's all possible. Like Arrieta, Pivetta is one of those arsenal pitchers than teams covet bcause he has the talent to be a very good pitcher. Apparently Bloom is not the only one to think so, as Tampa was also trying to acquire him, thinking he could be the next Glasnow.
Now of course, the opposite could also happen. As the immortal Boof Bonser (391 IP, 5.12 ERA, 84 ERA+) also had similar numbers through his age 27 season. Boof would go on to throw only 25 innings for the rest of his career due to some injury issues.
So is Pivetta another Arrieta or Bonser or, more likely, somewhwere in between? And if so, which one is he closer to and how far away?
