Lotte resolved internal issues that received the most attention in the stove league on the 10th. At the same time, it caught both team closer Kim Won-joong and setup man Koo Seung-min, who were qualified as free agents. Kim Won-joong has a total of 5.4 billion won for four years, including options, and Koo Seung-min has a total of 2.2 billion won for 2+2 years. Both players had a great affection for Lotte, which has been accompanied for more than 10 years since joining the team, and they wanted to remain "Giant's Man" without looking at the opportunity to sign with other clubs on a slightly better condition. Lotte also did not recruit players from outside, but it is expected that key bullpen players will be able to face the next season with responsibility and motivation. 

Kim was a rising star when he joined the team, but he elevated his value after transferring his position to a bullpen pitcher. Thus, Kim Won-joong had 132 saves and Koo had 121 holds. Both of them rank No. 1 pitchers in the Lotte franchise. 

Kim Won-joong has made more than 25 saves in all of the last five seasons except for the 2022 season. Koo had only 13 holds in the 2024 season due to poor performance in the early stages, but recorded more than 20 holds in the previous four seasons. If the two pitchers set average records, they can surpass 200 holds and 200 saves, respectively, within the contract period. 
Kim Won-joong is ranked third in overall saves after Kim Jae-yoon (Samsung Lions) with 180 saves and Lee Yong-chan (NC Dinos), who made 173 saves. Only five players have made more than 200 saves in all time. 

Koo ranks fourth in current holds after Jin Hae-soo (Lotte), who recorded 157 holds, Kim Sang-soo (Lotte), who had 137 holds, and Kim Jin-sung (Lotte), who had 127 holds. The other three pitchers are well over mid-30s. The top in overall holds is Ahn Ji-man (retired). Koo can surpass 200 holds during his contract period to become the top in overall holds. 

Kim Won-joong and Koo Seung-min were also leaders of the Lotte pitching staff. They were also highly respected by young fielders. Their stay is expected to have a positive effect on the team's internal atmosphere.
