Sung-mun Song represents the San Diego Padres' biggest swing thus far at attempting to fix their offense, though he's more utility player than middle-of-the-order slugger.
That's not to say he can't be an impact addition. He's coming off a season in which he posted a .917 OPS in 144 games, and he also hit career highs in home runs (26) and stolen bases (25). Those numbers will naturally decline as he transitions from the KBO to the MLB, but he's got the defensive versatility and all-around game to feature regularly in Craig Stammen's lineup.
But if the team wants a true starter at first base — or a potential replacement for Jake Cronenworth if he's traded away — they may turn to Kazuma Okamoto.
