regular season play. On March 30, 2018, Neshek was placed on the 10-day disabled list with a right shoulder strain. On July 1, he was activated off the disabled list. In 2018 with the Phillies, Neshek was 3–2 with five saves and a 2.59 ERA, and 15 strikeouts in 30 relief appearances. He was the eighth-oldest player in the National League. In 2019 with the Phillies, Neshek pitched only 18 innings, and was 0–1 with three saves and a 5.00 ERA in 20 games before his season ended due to a hamstring injury he suffered in June that ultimately required surgery in September. He was the fourth-oldest player in the National League. Pitching style Neshek has a very unorthodox style of delivery that transitions from starting at a submarine angle to finishing sidearm with an explosive thrusting motion. Near the release of the pitch, his torso and arm angle in a moderate "V" shape. He developed the delivery after being struck in the forearm with a ball in high school by C. J. Woodrow (a former Philadelphia Phillies farmhand). He then began to throw sidearm and play shortstop due to his injury. When it healed, he could not change back to over the shoulder and his unique delivery stayed the way it is. He still has a lump in his forearm where he was struck. The delivery has earned mention on SportsCenter as well as Baseball Tonight. Professional baseball scouts have had a divided opinion on the issue. Some were worried that this violent-looking delivery would lead to arm problems. Others considered the delivery to be an asset, as right-handed batters have a very difficult time seeing the ball. For example, José Marzán, his former manager with the Single-A Fort Myers Miracle, believes that one of Neshek's greatest strengths is his ability to have enough strength to throw hard from such an angle, as his fastball used to top out around prior to his Tommy John surgery. Neshek has had great success in both the minor and major leagues as a reliever, averaging more than a strikeout per inning pitched. After joining the Cardinals in 2014, Neshek's sinking fastball showed effectiveness well-above expectations through May 21. With a mean movement of 10.9 inches, it averaged more horizontal movement than any other pitch from any other reliever on the Cardinals staff, which was 1.3 inches more than Carlos Martínez' two-seam fastball.
