Chicago White Sox righty Lucas Giolito isn't having a fantastic start to the season, but it can't be denied that he's got one of the best turnaround stories in the MLB today. He was highly regarded as a prospect before hitting the big leagues, but in his first three seasons in the majors, he went just 13-17 with a 5.48 ERA and a 5.68 FIP.

However, Giolito has been so much better ever since, and it's largely because of a change in mechanics as noted by Brian Menendez of FiveThirtyEight.

“Before 2019, Giolito’s arm swing was longer, extending far behind him before coming up to his release point. After he made the adjustment, his arm went from his glove to his release point in a shorter, more intentional path. This shorter arm path, which is more common with infielders, is generally not taught to youth pitchers because it goes against the old wisdom of “reaching back and firing.” But the shorter action seems to be exactly what Giolito needed.”

Baseball is a game of subtleties. For Giolito that seemingly minor shift in his delivery has given his career a shot in the arm. Not only that, but other pitchers are also trying to follow his lead, as guys like Shane Bieber, Brandon Woodruff, and Joe Musgrove are some of the hurlers following the example of the White Sox's ace.

Even though Giolito is only 2-3 with a mediocre 4.54 ERA and a 1.29 WHIP this year, albeit with a FIP (4.13) lower than his ERA, it could just be a matter of time before he gets out of his slump, as he tries to help Tony La Russa's club stay on top of the AL Central.
