MLB Starting Pitcher Updates: Kikuchi's Resurgence and Flaherty's Struggles

Yusei Kikuchi's Turnaround

Earlier in the season, Kikuchi's performance with the Angels was inconsistent, but a grip change and increased reliance on his curveball have led to a significant improvement.

His fastball velocity has remained consistent, but the key change has been his curveball usage, now at 21% in June, with a 16.8% SwStr% and 38.3% CSW. He strategically uses the curveball against righties, making it a crucial pitch in his arsenal. Kikuchi's ability to adapt his pitching strategy has been pivotal in his improved performance.

Justin Wrobleski

Justin Wrobleski has lowered his arm angle almost five degrees from last season. That’s a pretty substantial difference. The lower arm slot may have contributed to his increased extension and velocity, but we do know that it has likely impacted the change in his overall slider movement.

Mike Burrows

Mike Burrows has lowered his arm angle quite significantly after his two appearances in May. It doesn’t seem to have done much to the overall shape of his pitches, but it has shifted the attack angle on his pitches.

Quinn Priester

The first thing that stands out is that his cutter usage jumped back up in June, in addition to ticking back up in velocity. He has used the pitch just 13% of the time against righties during those last eight starts, but 27% of the time against lefties.

Jack Flaherty's Difficulties

Jack Flaherty's recent starts have been challenging, marked by a high ERA and WHIP. Although his pitch usage and shapes haven't drastically changed, the effectiveness of his curveball has declined.

His slider has struggled since May, putting more pressure on his curveball. While there's no major red flag, hitters may be identifying and sitting on his curveball more effectively. Flaherty's ability to adjust and regain command of his pitches will be essential for future success.

What contributed to Yusei Kikuchi's improved performance?

Kikuchi's improved performance is largely due to a grip change and increased reliance on his curveball, especially against right-handed hitters.

Why has Jack Flaherty struggled recently?

Flaherty's struggles stem from a decline in the effectiveness of his curveball and a general struggle with his slider, making him more vulnerable.
