Law's take
This take may be insufficiently warm for the hot stove, but the trade that sent Daulton Varsho from Arizona to Toronto for Gabriel Moreno and Lourdes Gurriel might be good for both sides.
Varsho had a quiet breakout in 2022, hitting .235/.302/.443 in hitter-friendly Phoenix but playing elite defense in the outfield while also going behind the plate for 31 games. He’s not a good defensive catcher but is a plus runner and athlete who was way above league average in center field and right field last year, racking up 18 Outs Above Average and 16 runs prevented by Statcast’s measures — ranking fifth and third in baseball in those categories, respectively. He’s become a fairly extreme dead-pull hitter, sacrificing contact and some contact quality for more power. He hit 27 homers last year, a career-high at any level, but it came with the highest strikeout rate he’s posted except for his debut in the pandemic-shortened 2020 season.
In exchange for Varsho, who has four years of team control remaining and is arbitration-eligible for the first time this year as a super-two player, the Diamondbacks get the Blue Jays’ No. 1 prospect going into 2022, catcher Gabriel Moreno, and outfielder Lourdes Gurriel. Moreno is a super-athletic catcher who offers plus defense and a high-contact approach that probably won’t produce much power but should lead to strong on-base percentages because he makes so much line-drive contact. He’s got an above-average arm, blocks and receives well, and has made huge strides in working with pitchers given his age. He’s very aggressive at the plate, rarely walking or striking out because his plate coverage is so good, although it’s possible he’ll have to make adjustments in that area against big-league pitching. He’s ready to take over as the regular catcher in Arizona, which would make Carson Kelly a backup or a potential trade piece, although it might be two or three years before we see Moreno get to that 4-5 WAR ceiling.
Gurriel had a disappointing 2022 season as all of his power evaporated, but he underwent surgery after the season to address a broken hamate bone, which could easily explain the power outage. He’s a free agent after 2023, and could give the D-Backs an offensive boost in left field, allowing them to trade center fielder Alek Thomas, or could be traded himself. He needs to hit for some more thump to be even a passable regular, as he’s a below-average defender anywhere, even in left field, and doesn’t walk.
The trade would appear to help both clubs, since the Blue Jays did have a surplus behind the plate, and the Diamondbacks have a surplus in the outfield that’s only going to get worse over time. That said, I think I prefer Arizona’s end of the deal, as it took on a bit more risk to get a lot more ceiling – and it gets six years of Moreno versus Toronto getting four of Varsho. Arizona is still building toward contention and is better situated to take on that risk to get a potential superstar in Moreno, while the Blue Jays may have decided to go with the surer thing in their Alejandro Kirk/Danny Jansen catching tandem. Kirk played 78 games at catcher last year and 51 at DH, hitting .285/.372/.415 for a 3.9 rWAR/3.8 fWAR season. Jansen caught 63 games, with three starts at DH, and hit .260/.339/.516 for 2.9 rWAR/2.6 fWAR. Jansen has never been able to stay healthy for a full season, reaching 400 plate appearances only one time in his professional career, in 2017, and I’m not confident at all that he could hold this kind of production if he played every day. He’s in the perfect spot, with Kirk the better hitter and better able to handle the higher workload.
If you’re the Blue Jays, even if you completely believe in Moreno’s potential, the odds of him outproducing the Kirk/Jansen duo in 2023 are just not that high. There were only two 5-WAR catchers in baseball last year per Fangraphs, J.T. Realmuto and the recently traded Sean Murphy. Kirk and Jansen produced 6.4 fWAR between them — although that includes Kirk’s DH time — but even if we conservatively set their total catching value at 5 WAR, you can see how high a bar that is for Moreno to clear right now. I believe he’ll get there in time, but the Blue Jays value winning in 2023-24 over the long term, while Arizona has the luxury of patience and can bet on Moreno becoming that 5-win catcher, even if it doesn’t come for a few years. The D-Backs have the better chance to end up with more total value out of the trade, but the Blue Jays are clearly a better team right now than they were before the deal, as Varsho is at least a 3-win upgrade over Gurriel if we just assume he takes over in a corner; and if Kevin Kiermaier gets hurt the Jays now have a viable alternative in center. Each of these teams had a surplus of good players and made a very old-fashioned sort of trade that leaves both clubs better off. What a concept.
