Sung-mun Song's Outfield Test Could Fix What Ails Padres' Bench

The San Diego Padres' signing of former KBO infielder Sung Mun Song wasn't difficult to pin down in its motivation. A versatile infielder coming off a 25/25 season with Kiwoom is a player that virtually every team in baseball would want to add to their roster. So, it's a certain level of victory that the team was able to sign him to a four-year deal at an affordable price point, even if there isn't an obvious position for him to start at in the present moment. 

While A.J. Preller could still seek to make a move and trade someone like Jake Cronenworth, the team has options in how they deploy their newest positional acquisition. He could flip Cronenworth back over to first base while Song handles everyday duty at the keystone. The team could also keep Cronenworth at second, insert some sort of platoon involving Gavin Sheets and Luis Campusano (assuming the team doesn't sign an everyday first baseman), and utilize Song as a multi-positional component in their lineup while rotating the designated hitter spot. In any case, it sounds like the team is exploring additional contingencies in order to ensure Song's bat is in the lineup as frequently as possible. 

Reports emerged around the holidays that the team was considering letting Song spend some time on the outfield grass. New manager Craig Stammen confirmed as much, stating that the goal was to have his bat in the mix above all. It's an interesting proposition, but one that doesn't feature quite the same level of certainty as his work on the infield might. 

Presently, the Padres have their three starting outfielders in place. Fernando Tatis Jr. will continue his post as one of the game's best defensive right fielders. Jackson Merrill has center locked down for the next decade. Trade deadline acquisition Ramón Laureano, who is in a contract year playing on a club option, will handle left field duties. Tatis and Merrill are stars and, as such, everyday players, while Laureano was split neutral in a strong year at the plate. That's not necessarily a group that lends itself to too much flexibility.

The 2025 Padres were hit with some brutal injury luck. Perhaps nobody fell more into that cycle than Merrill, who endured multiple stints on the injured list throughout the year. Laureano also missed the end of the season, while Tatis likely had various points at which he could've used a string of days off, particularly after absorbing multiple hit-by-pitches against the Los Angeles Dodgers in June. With very little offensive upside behind the starting trio — Bryce Johnson and Tirso Ornelas don't really move the needle — it could certainly behoove Stammen to see if Song has the chops to serve as a supplementary piece in the outfield puzzle in order to ensure the offense doesn't experience the kind of fall off they did last year when games were missed. If you get lucky and don't need that type of support in the way that the Friars did last season, then at least you've got someone worth throwing out there for the odd day off or late-game situation.

Ultimately, though, this exploration is about expanding the bench at large. It wasn't only the outfield that suffered from the team's lack of depth in 2025; it was virtually everywhere. With Luis Campusano already set to occupy a spot as the team's backup catcher, the team needs to be able to maximize what they have in their remaining three players on the bench. 

Last year's reserve group featured the likes of Jose Iglesias, Johnson, and a host of other players that were largely out of the organization by the end of the year. Part of such heavy turnover was due to the fact that it was simply not a versatile group, save for Iglesias. The support just wasn't there when the team needed someone to step in whether in the short or long term. 

As such, it makes complete sense for Stammen and the Padres to consider Song in the outfield ahead of the 2026 campaign. Even if he's set to be utilized as primarily an infielder, an expansion of his skill set — assuming Song proves capable of handling such duty — provides the team with extra coverage in the outfield in addition to what he was already set to bring to the infield mix. Regardless of how it all shakes out, the fact that the Padres have a moveable player on their roster capable of providing notable offensive production is a really exciting prospect against what the team was working with last season.
