Angels and Padres Look for Upside on the Left Side

The Angels were the busiest team in baseball during the first month of the offseason, signing Yusei Kikuchi, Travis d’Arnaud, Kyle Hendricks, and Kevin Newman, and trading for Jorge Soler. Then, after a quiet period throughout December and January, they returned to action last week, agreeing to a one-year, $5 million pact with Yoán Moncada. He will reportedly take over for Anthony Rendon as their primary starter at third base.

Meanwhile, the Padres are waking from an even longer hibernation. While the Dodgers, Diamondbacks, and Giants have been hard at work improving their rosters this winter, the Padres have been quiet. Their only notable move prior to February was re-signing catcher Elias Díaz. On Friday, they finally broke their silence and added not just one, but two major league free agents: Connor Joe and Jason Heyward. The two are expected to share duties in left field. Joe will earn a guaranteed $1 million on his one-year deal. The terms of Heyward’s contract, while presumably quite similar, have not yet been reported.

Angels Sign Yoán Moncada

We should have seen this coming. Back in December, the Angels reportedly expressed interest in a trio of third basemen on the offseason trade market: Nolan Arenado, Eugenio Suárez, and Alec Bohm. They were also linked to a pair of big-name free agent sluggers entering their age-30 seasons: Pete Alonso and Anthony Santander. So, of course, the Angels found a way to get the best a mediocre approximation of both worlds.

Moncada has had a career trajectory that few, if any, can relate to. There was a time when his star was so bright that he was often mentioned in the same breath as fellow international phenom Shohei Ohtani. Even as a teenager, he looked like such a stud that the Red Sox shattered international signing precedent to give him a $31.5 million bonus, which cost them another $31.5 million in penalties. Less than two years later, he was such a highly regarded prospect that some wondered if the Red Sox made a fatal mistake by trading him to the White Sox for Chris Sale.

Of course, Moncada wasn’t the first prospect to garner so much hype, nor was he the first top prospect who failed to reach his full potential. What makes him so interesting is that he did discover his ceiling – he just couldn’t stay there. In 2019, his age-24 campaign, Moncada played 132 games, swatted 25 homers, swiped 10 bases, and produced a 139 wRC+ en route to a 5.2-WAR season. That’s the kind of player the Red Sox thought they were signing when they gave him a record-setting bonus. That’s the kind of player the White Sox thought they were acquiring when they gave up one of the greatest starting pitchers of this generation to get him.

Sad to say, Moncada has never been that kind of player again. Everyone has a theory about the cause of his decline, from long COVID to the deadened ball, but regardless of the explanation, the fact of the matter is that Moncada was not able to make a consistent impact for the White Sox from 2020-24. His bat dropped off a cliff in 2020. He bounced back to post 3.7 WAR in 2021, but after that, injuries and underperformance became the defining themes of his late 20s. From 2022-23, he put up an 86 wRC+ and just 2.0 WAR over 196 games.

Moncada got off to a nice start in 2024, slashing .282/.364/.410 over the first two weeks of the season before a left adductor strain forced him to the injured list. Although he was initially expected to return in July, his rehab was put on pause for six weeks in the summer, first due to whatever on earth “anticipated soreness” is and later because he was oh-so-vaguely “still kind of feeling something.” He finally got back to Chicago in mid-September, after tearing up Triple-A on a rehab assignment, only to sit on the bench for the worst team in modern baseball history.

The White Sox had a dozen more games to ride out and roughly 450 plate appearances to fill. And yet Moncada appeared in just one of those games and took just one of those trips to the plate. If you blinked at the right moments, you might not have realized he ever came off the injured list at all. Over those final 12 games, White Sox batters produced a 70 wRC+ and -0.6 WAR. Their designated hitters went 9-for-50 with a 49 wRC+. Their third basemen were even worse, going 4-for-44 with a -2 wRC+. Yet, the only work the White Sox offered Moncada was a 12th-inning pinch-running gig against the Angels on September 18. He struck out the following inning in his only plate appearance of the month. Nonetheless, he somehow finished the season as the most productive offensive performer on the team, because of course he did:

All that to say, Moncada’s performance in 2024 can’t tell us much about what to expect from him in 2025. Could he be the 5.2-WAR player we saw in 2019, or even just the 3.7-WAR player we saw in 2021? I mean, sure, I guess. He’s done it before, and he won’t even turn 30 until May. But Moncada put up 2.2 WAR over 208 games from 2022-24, and that’s the kind of player our Depth Charts projections expect him to continue to be in 2025 (1.3 WAR in 118 games). ZiPS is a little higher on him, while Steamer is a little lower, but ultimately, we’re talking about a slightly-below-average everyday player – if he can stay on the field enough to play every day. For many teams, that wouldn’t be enough to crack the starting lineup. For the Angels, however, Moncada could be a nice addition.

From about 2015 to 2020, Rendon was one of the few third basemen one might have picked over Moncada. The latter was a future superstar, but the former was already playing at that level. These days, Rendon is one of the few third baseman upon whom Moncada is, more likely than not, a meaningful upgrade. Here’s how the two compare according to several projection systems:

Saddled with unfair expectations as a teenager, Moncada has developed a bit of a reputation as a prospect bust. The truth, however, is that he was worth every penny the Red Sox paid him; they used him to get Sale, and Sale helped them win a World Series. What’s more, he gave the White Sox 13.8 WAR over parts of eight seasons and contributed to the team’s first two playoff runs since 2008. Overall, he provided Chicago about $110 million in value (using a simplistic $8 million per WAR estimate) while earning just a little over $70 million in salary. Perhaps he didn’t become everything he could have been, but he gave both of his teams more than he took. He can do the same for the Angels in 2025.

Padres Sign Jason Heyward and Connor Joe

On Opening Day in 2023, Juan Soto stood in left field for San Diego. The following season, the Padres braced for what could have been the worst downgrade since The Fresh Prince recast Aunt Viv. Jurickson Profar, he of the lowest WAR in baseball the year prior, was Soto’s replacement. The Friars dropped from first to 30th on our left field positional power rankings. Yet, things sometimes have a funny way of working out. Against all odds, the 2024 Padres had the top left fielder in the National League, according to WAR, for the second year in a row.

Unfortunately, the Padres then found themselves looking to replace their All-Star left fielder for a second consecutive winter. This time around, their solution is a platoon of the lefty-batting Heyward and the righty-batting Joe. And you know, for what it’s worth, both Heyward and Joe have better projections now than Profar did entering 2024:

To be crystal clear, those projections say far more about Profar’s remarkable 2024 season than they do about either Heyward or Joe. They do not suggest that Heyward and Joe this year are likely to outperform Profar last season. Nor do they suggest that either one of them has more upside than Profar did at this time last year. Heyward was an All-Star caliber player in his early 20s, and to his credit, he has enjoyed multiple bounce-back seasons over the past several years. Indeed, he is only two years removed from a strong 2023, when he put up a 120 wRC+ and 2.3 WAR in 124 games with the Dodgers. However, his 38th-percentile xwOBA that year suggested he was due for regression, and regress he did. Over 87 games with the Dodgers and Astros, he produced a 94 wRC+ and just 0.8 WAR in 2024. While the Padres are surely hoping to get something like the 2023 version of Heyward, a repeat of his 2024 is far more likely. He’s already 35 years old (he’ll turn 36 in August), and I’m more convinced by his overall 91 wRC+ and .301 xwOBA from 2021-24 than I am by his brief resurgence in 2023.

Joe is three years younger than Heyward but has never shown anything close to Heyward’s All-Star ceiling. In fact, he has never even had a year as strong as Heyward’s 2023. (There’s a reason the Pirates non-tendered Joe rather than pay his projected $3.2 million arbitration salary.) All things considered, Joe’s production over the first four proper seasons of his career has been pretty similar to Heyward’s declining performance in the same time frame. Joe has been the more consistent hitter, but Heyward makes up the difference as a better baserunner and outfield defender:

Heyward is used to working in a platoon; since 2021, only 12.9% of his plate appearances have come against left-handed pitchers. Joe, on the other hand, could benefit from less exposure to opposite-handed hurlers. He has a career 107 wRC+ against lefties and a 91 wRC+ against righties. His managers in Colorado and Pittsburgh made an effort to shield him from right-handed pitching, but they haven’t had enough quality options to use him in a genuine platoon role; 38.2% of his career plate appearances have come against lefties. Excluding his eight-game cup of coffee with the Giants in 2019, when 14 of his 16 plate appearances came against lefties, he has never had a season in which the majority of his plate appearances have come with the platoon advantage.

Are the Padres such a team to change that? They should be, although that is contingent on their making further additions. Ideally, Heyward would take the bulk of the work in left field, health allowing, while Joe would handle the short side of the platoon. However, the Padres might need Joe for more than just outfield duties – and more than just a platoon role. Considering his defensive success at first base (5 DRS, 2 FRV in 170 career games), and the massive hole San Diego has at designated hitter, I wouldn’t be surprised to see Joe playing plenty of first with Luis Arraez as the DH. Joe’s projected 95 wRC+ (per Steamer) against right-handers would be pitiful at first base, but the Padres don’t currently have many better options for either first base or DH — whichever position that Arraez is not occupying. The only player on their 40-man roster with a higher projected wRC+ against righties who isn’t already penciled into the lineup at a different position is Tirso Ornelas, a prospect who has yet to make his MLB debut.

If San Diego is going to beat its 33.2% playoff odds without making any major additions, it will need someone to step up to replace its most productive hitter from 2024. If that hero exists, it almost certainly won’t be Heyward or Joe. Instead, that production will need to come from Fernando Tatis Jr., Xander Bogaerts, Manny Machado, or, in a best-case scenario, some combination of all three. Still, Heyward and Joe are proven big league players, and there’s no doubt the Padres needed more of those on their roster. And hey, you never know. It’s not so long ago we were saying the same thing about Profar.
