2020, professional baseball is likely to be the first year of the Korean baseball 'Ace Generation Change'. Lee Young-ha, Choi Won-tae, and Park Se-woong's 'Right-handed Three Musketeers' are the momentum to take over the so-called 'left-handed troika', Ryu Hyun-jin, Kim Kwang-hyun and Yang Hyun-jong, who have been in charge of the national team for over 10 years.

most advanced player in the 'Next Generation Ace Competition' was Doosan Lee Young-ha, who made the most of the natives with 17 wins last year and played an active part in the Premier 12.

In the recent practice game, the power of fastballs and cutters remained, and the team was diversified by learning from the team's senior Yu Hee-gwan to a slow curve.

[Lee Young-ha / Pitcher Doosan: I think the goal is only to win. I think the team will do well and I'll think it will be done if I do well.] Although

it was 10 wins for 3 years in a row, Kiwoom Choi, who has been stagnant in skill development, is also said to have climbed one step this year.

Yesterday (25th) the SK Kangta Line was blocked up to 5 times with no scores, but the main weapon-based fastball was about 2km per hour faster than the regular season last year.

Lotte Se-woong Park, who was the most promising newcomer three years ago, but was caught in an injury, predicts a splendid resurrection.

Recently, the top speed per hour was 150 km, and the slider exceeded 140 km.

The fresh right-handed 'right-handed trio' is preparing to replace the Korean baseball mound.
