It was a night that Lotte Giants fans won’t soon forget. On April 15, 2026, at Seoul’s Jamsil Stadium, the Lotte Giants snapped a two-game losing skid by defeating the league-leading LG Twins 2-0, and the story of the evening belonged to the dynamic battery of starting pitcher Kim Jin-wook and catcher Son Seong-bin. Their performance not only halted LG’s impressive eight-game winning streak but also signaled a new era for Lotte’s mound management and team chemistry.
For years, the Giants have struggled to find stability behind the plate after star catcher Kang Min-ho’s departure to the Samsung Lions. Their high-profile acquisition of Yoo Kang-nam from the LG Twins in 2023, for a hefty 8 billion won, failed to deliver the desired results. The 2026 season, however, has seen a seismic shift in fortunes, thanks largely to the emergence of Son Seong-bin. Once a backup, Son has become the focal point of a debate: can a catcher truly control the flow of a baseball game? After recent events, the answer seems to be a resounding yes.
The April 15 matchup was a classic pitcher’s duel from the outset. Lotte’s lefty ace Kim Jin-wook, drafted first overall in 2021, delivered 6 and 2/3 innings of shutout baseball, scattering just three hits, issuing two walks, and striking out five. His command was razor-sharp, especially in tight spots against a lefty-heavy LG lineup. According to Kim, "LG batters weren’t reacting to low pitches, so I tried to attack with fastballs. Son kept signaling for the heater, and most of the strikeouts came thanks to his steady lead."
Son Seong-bin’s influence was felt not only behind the plate but also in the batter’s box. In the top of the third, with one out, Son stepped up against LG starter Lachlan Wells and launched the first pitch—a slider—over the left-field fence. It was Son’s first home run in 321 days, his last coming on May 29, 2025, against the Samsung Lions. That solo shot proved to be the game-winning run, and Son’s all-around performance earned him the game’s hero status.
But the Giants’ scoring didn’t stop there. In the eighth, Han Tae-yang drew a walk, advanced on Son’s sacrifice bunt, and eventually scored on a clutch RBI single by Jang Doo-sung. The insurance run gave Lotte’s bullpen—Park Jung-min, Kim Won-joong, and Choi Jun-yong—the cushion they needed to slam the door on LG’s offense, sealing the 2-0 victory.
Kim Jin-wook’s transformation this season has been nothing short of remarkable. After a disappointing 2025 campaign, in which he posted a 10.00 ERA over 14 games, Kim invested in himself during the offseason, traveling to Japan to overhaul his mechanics. The results are clear: his fastball velocity has jumped from an average of 143.8 km/h last year to the mid-146 km/h range this spring. He’s also added a changeup to his arsenal, inspired by former Lotte ace Dan Straily and MLB’s Tarik Skubal, creating a 15 km/h speed differential that’s baffling hitters. Kim’s improved command was on full display, with four of his five strikeouts coming via the fastball, three of them looking.
Son’s pitch calling has been a revelation for the Giants. Compared to Yoo Kang-nam’s more cautious, breaking-ball-heavy approach, Son has favored aggressive, fastball-first sequences, especially when Kim’s velocity is up. The numbers tell the story: in the nine games Yoo started, Lotte’s pitchers failed to record a single quality start and issued 60 walks. With Son behind the plate for four games, the staff has produced four consecutive quality starts, allowing just four walks in that span. The reduced pitch counts and walks have eased the bullpen’s workload, allowing for more effective late-game management.
The chemistry between Kim and Son extends well beyond the diamond. Both 2021 draftees, they’ve grown into their roles together, supporting and challenging each other. Kim often sends Son articles highlighting his achievements, hoping to boost his friend’s confidence. Son, for his part, keeps Kim grounded, offering honest critiques and urging him to stay focused. Their rapport was evident after the game, as Kim explained, "Son always tells me to believe in myself. Even when I wanted to throw a curve, he insisted on the fastball. I trusted him, and it worked out." Son added with a laugh, "The last pitch to Shin Min-jae, I thought it was a ball, but the ump called it a strike. It was thrilling as a catcher."
Son’s rise to starting catcher began on April 8, 2026, when he paired with Kim Jin-wook to snap Lotte’s seven-game losing streak against KT Wiz with a masterful 8-inning, one-run performance. Since then, Son has started every game, and the Giants’ pitching has stabilized dramatically. The duo even earned themselves nicknames: Kim is now dubbed "Sajik Skubal," a nod to MLB’s Tarik Skubal, while Son has drawn comparisons to elite catchers like Cal Raleigh of the Seattle Mariners.
The impact of their partnership isn’t lost on Lotte fans, who have been quick to label it the "Son Seong-bin Effect." The numbers back them up: dominant starts, fewer walks, and a newfound confidence on the mound. As columnist Yoon Jung-gil put it, "Whoever wears the catcher’s mask, the days of games slipping away due to timid pitching and frustrated fans are hopefully behind us."
For Kim Jin-wook, the journey has been about resilience and self-belief. "If I want to live up to the nickname fans gave me, I have to keep working," he said. "Every pitch, every game, I’ll give it my all." Son echoed the sentiment, praising Kim’s offseason dedication and predicting even greater things to come.
With their record now at 6-9, the Giants are still climbing the standings, but the foundation laid by Kim and Son’s partnership offers genuine hope. As Lotte prepares for the next stretch of the season, all eyes will be on this battery duo to see if their synergy can carry the team back to contention. One thing’s for sure: with Kim firing on all cylinders and Son calling the shots, the Giants’ faithful have every reason to believe in a brighter future.
