2023 in review

Paul Sewald was drafted in the 10th round in 2012, by the NY Mets out of San Diego State University. He was born and went to high school in Las Vegas. Joey Gallo, who is 3 years younger, went to the same high school as Sewald. Gallo has a home run and 3 RBI in 3 PAs off Sewald. Useless trivia facts.

Sewald made his debit for the Mets in 2017, and spent the first 4 years of his career pitching not very well for them, to the tune of a 5.50 ERA and 1.364 WHIP to go with a 1-14 record in 125 games. He was granted free agency in December of 2020, and signed with the Mariners in January of 2021. In 2021, it looks like he was part of a closer by committee with Seattle. Three different pitcher had more than 10 saves for them. For 3 years in Seattle he was a team mate of Anthony Misiewicz, who pitched in 7 games for us this season.

For the Mariners this year, he pitched in 43 games, a 3-1 record. He had 21 saves and 3 blown saves. He gave up 2 or more runs only 3 times. In the only game he gave up three runs, the Mariners led in the 9th inning 6-2 over the Giants so he entered in a non save situation. The other two games that he gave up 2 or more he entered in a blow out against the Angels and in a non save situation against the Astros. That is interesting, I kind of expected at least one of those 3 blown saves to have been in a game where he gave up 2 or more!

On July 31st, he was traded to Arizona for Ryan Bliss, Dominic Canzone and Josh Rojas.

His first save situation as a Dback did NOT go well. On August 6th, he came in in a 3-2 ballgame against the Twins and gave up home runs to Max Kepler and Matt Wallner. That series against the Twins was during our 9 game losing streak in the month of August. Sewald wouldnt give up another run for nine games. During the 8 game scoreless streak, Aug 12-24, he had 7 saves, 8 innings pitched struck out 9 to go with 5 walks. On August 26th he came into a 4-2 ballgame against the Cincinnati Reds and gave up 2 runs in an eventual 11 inning 8-7 loss. This was his only other blown save.

In September, he pitched in 9 games, 8 innings and had 6 saves. He gave up a home run, struck out 8 and walked 3. He appeared in the 9th inning of the tied September 16th Snakepit Game of the Year against the Cubs. He retired all 3 batters faced.

Looking at the 4 Dbacks that had four or more saves before Sewald’s arrival on July 31st (this is just looking at beginning of the season through that date):
Chafin had 8 saves, 12 holds and 4 blown saves.
McGough had 9 saves, 13 holds and 4 blown saves.
Ginkel had 3 saves, 1 hold and 1 blown save.
Castro had 7 save, 9 holds and 3 blown saves.

Sewald had 13 saves and 2 blown saves in his 20 appearances as a DBack in the regular season. He had 6 saves, including game 7 of the NLCS, and only 1 blown save in the post season against Texas.


Against the Milwaukee Brewers in the Wildcard round, he appeared in both games. He only gave up 3 base runners, in his two games, both saves and striking out 3. From my pxp recap of Game 1

Paul “seawall” Sewald now in the game. No Fernando Rodney experience, please. Contreras the first batter and strikes out. Santana, on the first pitch he sees, pops up to Thomas. One more out to get now. Mark Canha, 0-4 with 2 Ks on the night, he gets hit by a pitch. Sal Frelick now, Canha will take 2B on defensive indifference, Frelick flies out to Gurriel! We take game 1!

In the Dodger series, the NLDS, he appeared in games 2 and 3. He got saves both nights, an inning each to go with 2 strikouts and giving up only a single to Will Smith.

In the NLCS against the Phillies he appeared in 4 games, including games 6 and 7. He had 2 saves and a win. He struck out 6 in 4 innings pitched. In game 3, he got the win having pitched the top of the 9th inning in a game which Ketel Marte delivered a walkoff base hit against Kimbrel. He struck out the side in game 4, although he did give up a Kyle Schwarber double with a one run lead to make things interesting. Game 4 was the game that Alek Thomas had that amazing punch hit home run.

He gave up 6 runs on 6 hits in 2 appearances along with a blown save against Texas in the World Series.

2024 projections

FGs and Steamer both have him at a 3-3 record, appearing in 66 games and a 3.97 ERA to go with 26 walks and 75 strikeouts. BRs projection 4-3 record, 62 innings, 3.63 ERA walking 23 and striking out 71. I think they don’t view him as our “only” closer since they only project 16 saves.
