Welcome to SB Nation Reacts, a survey of fans across MLB. Throughout the year we ask questions of the most plugged-in Diamondbacks fans and fans across the country.
Paul Sewald was designated for assignment by the Arizona Diamondbacks yesterday, likely ending the reliever’s tenure with the team. On the broadest level, his time here was nothing special. He pitched 107 times in the regular season for Arizona, posting an underwhelming 4.95 ERA. The resulting 86 ERA+ is more or less the same as the likes
of Mark Melancon or Matt Peacock, players who are probably no more than footnotes in franchise history. Sewald is certainly not going to see his number retired by Arizona. But a couple of things likely elevate Paul’s place in the record, higher than those pitchers.
Firstly, he was a closer, reaching double digits for the D-backs in saves in three separate seasons. The only pitcher with more such campaigns is Jose Valverde’s four. He became only the sixth man to reach fifty saves for Arizona, and you have to go back a full decade to find the last to do so – Brad Ziegler in 2016. When he first arrived here, at the 2023 trade deadline, the D-backs had three different pitchers with at least seven saves – none of who reached even ten. He stabilized the position down the stretch run, saving 13 games in 15 opportunities, and was key as the Diamondbacks reached the post-season for the first time in six years.
Then there was his post-season exploits. There’s a good argument that, without Sewald, Arizona does not win the NL pennant. Through the end of the Championship Series in Philadelphia he pitched eight scoreless innings, allowing three hits and one walk, while striking out eleven. Of the D-backs’ nine wins to that point, Paul saved six of them and got the win in another. None were likely more crucial than games 3+4 of the NLCS, after Arizona had lost the first two. In the first, he came into a game tied 1-1 in the ninth, and put up a zero before Ketel Marte’s walk-off. The next night, he came in to preserve a one-run lead, and fanned Brandon Marsh, Jake Cave and Trea Turner.
But the 2023 playoffs then showed the worst of Sewald. In game 1 of the World Series, a two-run lead in the ninth inning evaporated off the bat of Corey Seager. And in game 5, a 1-0 deficit became an unsurmountable 5-0 one, after Sewald coughed up four runs in only 20 pitches, becoming the last Arizona pitcher to throw in the post-season to this date. A World Series ERA of 27.00 illustrated how, even in a profession known for volatility, Sewald seemed particularly mercurial. We saw that again in 2024. Through the end of June, he was perfect as a closer, on a streak of 17 scoreless outings, and with a 0.54 (!) ERA. He didn’t reach the end of July, after a month where he allowed 12 earned runs in 10 innings.
He left as a free agent at the end of the year, and given the July cloud, his return to the team in 2026 was something of a surprise. He was cheap enough, at $1.5 million, and won the role of closer out of spring training – to the concern of many. Initially, Paul was seen as a bridge until established arms Justin Martinez and A.J. Puk were healthy. We’re still awaiting Martinez, and Puk won’t be back at all. Sewald kept plugging away and outperformed many, far more expensive closers. He had 22 saves at the break, a total passed only twice in Arizona history. Again, July proved the unkindest month and he was relieved of duties by the end of it once more.
A brief stint in low-leverage situations proved unsuccessful, and with the team needing a long reliever, Paul was found to be surplus to requirements. But, overall, looking at the entirety of his tenure back to July 2023, how do you rate Sewald’s time in Arizona? Do you look at the mediocre ERA and see a pitcher who was lucky to get as many saves as he did? Or do you weigh the run to the World Series in 2023 and see a man who got the job done, almost whenever the team needed it most? That’s what the poll below is for – as usual, feel free to explain your decision in the comments.
