Overview of Zac Gallen’s 2023 Season

Gallen, a seasoned right-handed pitcher, faced challenges during the 2023 MLB season. Initially, he was considered a strong contender for a lucrative contract, potentially exceeding $100 million. However, his performance dipped significantly, culminating in a 4.83 earned run average (ERA), the highest of his career, alongside a career-low strikeout rate of 21.5%.

Season Highlights and Struggles

The season began poorly for Gallen, as he allowed over five earned runs per nine innings during the first four months. By the All-Star Break, his ERA had risen to 5.40, and he maintained a 5.60 ERA through 127 innings by the trade deadline. This prompted the Diamondbacks to make significant roster changes.

• Key players traded: Josh Naylor, Eugenio Suárez, Merrill Kelly, Shelby Miller.
• Gallen’s strikeout percentage dipped: 20% in his final games.
• Performed better post-trade deadline: 3.32 ERA in last 65 innings.

Impact and Future Prospects

Despite a rocky start, Gallen’s later performance helped keep the Diamondbacks competitive in the Wild Card race. The team went 7-4 in his final 11 outings, showcasing some signs of recovery. However, it should be noted that his batting average against decreased, aided by a .232 average on balls in play.

Pitching Arsenal and Adjustments

Gallen’s fastball averaged 93.5 mph, consistent with his career averages. However, opponents have increasingly capitalized on its predictability. Although he introduced different pitches, including a knuckle-curve and changeup, his fastball usage decreased in favor of changeups toward the season’s end. Statcast metrics suggest that despite the high ERA, Gallen’s expected ERA was more favorable at 4.28.

As he prepares for the upcoming season, Gallen aims to rebound and return to his peak performance levels. The Diamondbacks’ confidence in his potential hints at adjustments that may benefit Gallen’s effectiveness on the mound.
