Pitching Style and Technique
Fastball
Janssen’s fastball was characterized by a velocity ranging from 92 to 95 miles per hour, depending on the phase of his career. He relied on a four‑seam delivery that allowed for consistent release points and effective horizontal movement. The fastball served as the primary pitch in his arsenal, often used to overpower hitters or set up off‑speed pitches.
Slider
The slider was Janssen’s secondary pitch and a key component of his matchup strategy. It possessed a sharp downward break and lateral movement, making it difficult for batters to track. During high‑pressure situations, Janssen frequently deployed the slider on two‑strike counts to induce swings and misses or weak contact.
Changeup
Although not as prominent in his repertoire, Janssen occasionally used a changeup to disrupt timing. The pitch offered a slower velocity, typically in the low 80s, and a slight vertical drop. By mixing the changeup with his fastball and slider, he was able to keep hitters off balance, especially against left‑handed batters.
Approach on the Mound
Janssen was known for his disciplined approach, selecting pitches with the intent to induce swings on his best offerings. He maintained a high strikeout-to-walk ratio, indicative of his control. In addition, his ability to read hitters and adjust pitch sequences contributed to his effectiveness in maintaining leads or preventing runs.
Strengths and Weaknesses
Key strengths included consistent velocity, sharp slider, and strong command. Janssen's experience in relief roles allowed him to handle high‑leverage scenarios with composure. Weaknesses sometimes involved periods of decreased velocity or reduced effectiveness against certain hitters, leading to inflated ERAs during specific stretches of his career.
