Kiwoom's Jang Jae-young, who made his debut last year with the second-largest down payment of 900 million won, showed a different look in the demonstration game.
With more stable control, he played without a score in 4 games in a row.

Jang Jae-young, who was selected as the number one rookie of the year last year, but could not overcome the chronic control anxiety, is looking for a solution with an anomalous 'ball combination' in this demonstration game.
His top speed is 155 km/h, but when he increased the proportion of a variable ball rather than a swaying fast ball, the power of the fast ball was revived as well.
Last year, 73% of all pitches were fastballs, but in this season's demonstration games, the proportion of fastballs dropped significantly to 53%.
Yesterday against Hanwha, he threw more change balls than fastballs, cooked batters, and scored four goals in a row with one scoreless inning, raising hopes for a rebound.
Hanwha native ace Kim Min-woo delivered a perfect pitch to block the Kiwoom line with a no-hit in five innings.
Last year, the rookie of the year, KIA Eui-ri Lee, who made her first appearance in the demonstration game belatedly due to a finger blister injury, announced that she was in good health by preventing a scoreless inning with a fastball with a maximum speed of 148 km/h.
LG's 5th-year prospect, Song Chan-ui, took the lead in home runs in the demonstration game with a surprising performance by hitting the 3rd home run in the demonstration game against NC.
