Darin Ruf
Back when the New York Mets acquired Daniel Vogelbach, early analysis on this site was it hurt the Mets in the short-term. It was also noted as a bizarre trade as the Mets in-house options were more than capable of handling the duties the Mets were seeking Vogelbach to handle.
As we have become further removed from the trade, we see it is a trade which has continued to hamper the Mets.
This is not to say Vogelbach has been bad. In fact, Vogelbach has been better with the Mets than he has at any spot in his career posting a 130 OPS+ with the Mets.
That may be news to some Mets fans as they have become frustrated with the designated hitter. They will point to his numbers with RISP (.200/.455/.200) and his lack of power. While productive as a DH, Vogelbach is not the classic power hitter you expect from the position, or frankly, someone with his physique.
That is very noticeable when Mark Vientos is raking in Triple-A. So far this season, Vientos is hitting .331/.416/.677 with 11 2B, 12 HR, and 35 RBI. By every measure, Vientos should be in the majors.
However, he isn’t, and it is inextricably linked to Vogelbach. Yes, fans are frustrated with him, but he has been productive at the plate. As a result, the team is not going to have Vientos join the club to sit.
This is a consideration Billy Eppler should have had last year and this past offseason. Keep in mind, Vientos was raking with Syracuse last season, but the Mets outright refused to give him a look at DH. Instead, they opted for the Vogelbach/Darin Ruf tandem at the trade deadline.
Vientos did not succeed in a short-side platoon in September. This is a reason not to call him up now no matter how much he hits. Arguably, he’s the Mets best DH option now (and probably was last season), but he’s blocked due to the veteran forward approach of Eppler and Buck Showalter.
The trade is made worse by Colin Holderman‘s success with the Pittsburgh Pirates. So far this season, Holderman is 0-1 with a 2.81 ERA, 1.313 WHIP, 2.3 BB/9, and a 10.7 K/9. He has established himself as a very good late inning relief option.
The Mets could use Holderman now, especially after the Edwin Díaz injury. At the moment, David Robertson, Drew Smith, and Adam Ottavino have been the only real reliable relievers so far this season. Past them, the Mets have been cycling through injured relievers and hoping for one or two good outings from the Jimmy Yacabonis and Dennis Santana of the world before they hit the IL or are designated for assignment.
Of course, the there is also the matter of how the Holderman for Vogelbach trade led to the Mychal Givens trade last season. Therein lies the real issues with the Vogelbach trade.
The value of Holderman for Vogelbach was fine. In fact, it might’ve been an underpay for the Mets. However, that trade has forced the Mets into many bad and short-sighted decisions. As a result, we see Vientos stuck in Triple-A, and the Mets still seeking power and production from players who were never going to provide it – players like Vogelbach.
Now that Carlos Correa has signed with the Minnesota Twins, the question is now what? The New York Mets still need to add another bat, and with Michael Conforto signing with the San Francisco Giants, their options have become even more limited.
One of the better hitters left on the market is Trey Mancini, who played for Buck Showalter with the Baltimore Orioles. At 31, it does seem as if he is moving past his prime, but he does have some thunder remaining in his bat.
Last season, Mancini had a 104 wRC+. That came on the heels of a 105 season, which was a drop from his 132 mark in 2019. Of course, two things must be noted here. First and foremost, he missed the 2020 season due to cancer. Second he was thriving with the Orioles before being traded to the Houston Astros at the trade deadline.
Looking at Baseball Savant, Mancini has seen his average exit velocities and barrels drop each of his past five seasons. However, he did hit enough last season to be an effective DH. He also appears to be one of the players who could benefit from the shift.
Last season, Mancini had a .228 wOBA against the shift. When he was not shifted, Mancini had a .314 wOBA. It should be noted the shift numbers have been anomaly for his career with him posting strong numbers against the shift for most of his career. Then again, that was back when he had a higher exit velocity.
Where Mancini does his damage is against right-handed pitching. In 2022, he had a 111 wRC+ against right-handed pitching against an 88 wRC+ against left-handed pitching. For his career, Mancini is actually better against left-handed pitching with a 112 wRC+ against a 111 against right-handed pitching.
Part of the reason for the change in numbers was his role with the Astros. Before the trade deadline, Mancini was a 98 wRC+ against left-handed pitching while with the Orioles. That dropped to a 64 with the Astros. It should also be noted Mancini is typically a much better first half player than second half player.
To a certain degree, we see Mancini did not and would not thrive in the role Darin Ruf had last year. On that note, Ruf did not thrive in that role. Ruf and Mancini are really everyday players or semi-regular players who have platoon advantages.
This is again where Daniel Vogelbach presents a problem. His numbers against right-handed pitching cannot be matched by anyone, but his possible platoon partners do not thrive on limited duty. That would seem to qualify for Mancini, who at this point in his career is an everyday DH who can fill-in at a position for a game or two. No more.
Perhaps, Billy Eppler can start moving things around to make Mancini or someone else a fit. However, it does appear too late in the game to start doing that. It seems Vogelbach is in place at DH. While the Mets should look to improve on Ruf, and Mancini promises to be that, it does not appear he can truly fulfill that role.
Right now, the New York Mets are rumored to be listening to offers for Carlos Carrasco. This makes sense because the Mets should listen to offers on all of their players and make deals if it improves the team. That should go without saying.
There is also the matter of clearing up payroll to permit the Mets to address their bullpen, outfield depth, and find a better solution than Daniel Vogelbach and Darin Ruf at DH. Mostly, the Mets would be better served by having David Peterson in the rotation.
Peterson, 27, was the Mets 2017 first round pick (20th overall) out of the University of Oregon. At his age, this is exactly the time you would be expecting his career to take off, but frankly, to date, it has not gotten started. There are several reasons why that has happened.
After a promising 2020 rookie year in the pandemic shortened season, he predictably struggled in 2021 before succumbing to a shoulder injury. This would have the Mets under Steve Cohen bypass him as they looked to build an elite rotation designed to win the World Series. Despite that, Peterson would be needed, and he would have his moments.
Overall, as a starter, Peterson was 6-5 with a 3.86 ERA, 1.341 WHIP, 4.1 BB/9, and a 10.9 K/9. He would also average 4.2 innings per start. The caveat there was in two September starts, he threw four innings total over two horrific starts. This came at a time the Mets were working to move him to the bullpen for the postseason. Without those two starts, he averaged 5+ innings per start.
No, these aren’t earth shattering numbers, and yes, the walks/control were an issue. However, there are some caveats with these numbers. He was bounced back-and-forth from the rotation and bullpen AND between the majors and Triple-A. That takes its toll on a player. Notably, Peterson did perform better in the majors than in Triple-A.
Another factor is Peterson did not get to really work with Jeremy Hefner the way the rest of the Mets pitching staff did. Notably, we did see Hefner help hone pitchers mechanics and work on their control. This was most notable with the work Hefner did with Edwin Díaz to get him to repeat his landing spot on the mound. As a result, we not only saw the best we’ve seen from the closer, but we also saw Díaz go from a 4.9 BB/9 in 2020 to a 2.6 last season.
Arguably, if Peterson is going to take that next step, he is going to need Major League coaching, be surrounded by pitchers like Max Scherzer and Justin Verlander for a full season, and really, he is going to need a chance.
Looking at the data, he is worth that chance. Per Baseball Savant, Peterson generates excellent extension, and he has a very good whiff%. That is shown with Peterson striking out 27.8% of the batters he faced last season, which is excellent. Part of the reason for that is despite lower fastball velocity and spin (which should be expected with a sinker) is Peterson’s excellent slider numbers.
Highest single-season slider whiff% by a lefty pitcher in the Statcast era (min. 250 sliders swung at):
Andrew Miller: 54.7% ('15)
Amir Garrett: 53.7% ('19)
Patrick Corbin: 53.1% ('18)
Corbin: 51.4% ('19)
Robbie Ray: 49.5% ('17)
Corbin: 49% ('16)
DAVID PETERSON: 47.9% ('22) pic.twitter.com/vSAd5nAdLQ— Mathew Brownstein (@MBrownstein89) December 1, 2022
It is genuinely a strikeout pitch. Batters whiffed 47.9% of the time against the pitch. In and of itself, it is worth investing in that pitch to see what more the Mets could be getting out of Peterson. That slider is a hidden gem on this Mets staff, and they need to see it in the majors instead of Triple-A.
Put another way, Peterson still has a lot of upside. In many ways, he is still raw and needs more coaching and opportunities. For an older Mets rotation, they actually need Peterson’s upside. They need the younger starter who can surprise and have a good year. Somehow, some way, the Mets just need to get Peterson into the rotation and watch him take that next step because that next step could help the Mets win the World Series.
