At the start of the 2024 Cactus League season in Scottsdale, Arizona, Antonio Senzatela embodied the Colorado Rockies’ evolving pitching philosophy. After a difficult 2023 season marked by an overreliance on his four-seam fastball and a career-worst 6.65 ERA, the veteran right-hander began testing a more diverse pitch repertoire in Friday’s opener against the Arizona Diamondbacks at Salt River Fields. The Rockies’ coaching staff has emphasized reducing fastball frequency to improve overall effectiveness, aligning with Senzatela’s desire to secure a spot in the starting rotation for 2026.
Senzatela’s Opening Start Highlights Adjustments and Challenges
In Colorado’s narrow 3-2 loss to Arizona, Senzatela pitched two innings, giving up one run on three hits. The run came from a second-inning home run by former Rockies All-Star Nolan Arenado, who recently joined the Diamondbacks. Arenado capitalized on a hanging 82.9 mph sweeper from Senzatela, sending it over the left field berm for his spring debut homer. Despite the setback, Senzatela’s outing showcased the Rockies’ commitment to broadening his pitching mix.
Rockies manager Warren Schaeffer detailed the strategy behind Senzatela’s spring workload.
“He is working with brand new pitching coaches and they are collaborating very well together,”
Schaeffer said.
“They are giving him different things to use. So it’s the commitment to these new things that he’s being given. Also, a shrinking fastball percentage in terms of usage.”
Senzatela’s Reflection on Performance and New Arsenal
Following his appearance, Senzatela expressed a positive outlook on his physical condition and pitching arsenal.

“My arm feels really good and my body feels really good,”
he remarked.
“My sinker was working pretty good, too. My sweeper was a little high, and Nolan clipped it.”
He also commented on diversifying his pitching style.
“It feels like I have a lot of weapons to throw. Just not so many fastballs.”
This statement underscores his shift away from fastball dependency towards a more varied and strategic approach.
Manager Schaeffer Applauds Senzatela’s Spring Debut Despite Homer
Schaeffer emphasized that the home run allowed should not overshadow the progress made during Senzatela’s live pitching session.
“It didn’t matter that he gave one up to Nolan,”
Schaeffer noted.
“He was working on all of his pitches and got ahead in the count early. He did exactly what we wanted him to do today.”
This feedback highlights the coaching staff’s focus on development and adaptability in the early stages of spring training.
Nolan Arenado’s Spring Introduction with Diamondbacks
For Nolan Arenado, making his first spring appearance with Arizona after two successful stints in Colorado and St. Louis proved satisfying from a hitting perspective.
“It feels great to hit the ball hard,”
Arenado said.
“I feel like I saw the fastball pretty good, too, which is nice. Good to get that first (homer) out of the way in the first game.”
His early impact demonstrates his readiness for the 2024 season and adds intrigue to Rockies-Diamondbacks matchups.
Prospect Spotlight: Cole Carrigg Shines Before International Duty
The Rockies’ future also showed promise in Friday’s game as switch-hitting infielder Cole Carrigg, the organization’s No. 3 prospect according to MLB Pipeline, impressed at shortstop. Carrigg, who is set to represent Team Israel in the upcoming World Baseball Classic, contributed an RBI triple and demonstrated his dynamic playing style. Manager Schaeffer praised Carrigg’s approach and speed emphatically.
“It’s incredible — he plays like a wild horse with his hair on fire,”
Schaeffer said.
“I love the way he plays. We need more of that. But it’s just about him being here, refining some things. We talked in his player meeting this morning and said that exact word — it’s just all about refinement, without taking away his energy and what he brings to the table.”
Carrigg’s speed is a valuable asset for the Rockies, boasting 14 triples — the highest in the minor leagues in 2024 — and a combined total of 99 stolen bases over the past two seasons. His recent experience in Double-A Hartford reflects his potential as an impactful major league contributor.
Rockies’ Broader Pitching Strategy Under New Coaching
The revamped pitching philosophy extends beyond Senzatela, encouraging all starters in Colorado’s rotation to develop more diverse pitch arsenals to avoid predictability. Reducing reliance on high-velocity fastballs aims to lower opponents’ hitting averages and improve pitcher longevity. This approach was clearly signaled in Senzatela’s usage patterns this spring, and it remains a key focus point for the Rockies as they build toward a more competitive 2026 season.
Implications for the Rockies’ Season and Player Development
The early experiments with pitching mix alterations signify a crucial period of transition for Colorado’s pitching staff. By fostering versatility among starters and integrating learnings from new pitching coaches, the team hopes to reverse recent struggles and develop a deeper, more adaptive rotation. Antonio Senzatela’s development represents a microcosm of this organizational shift, and his optimistic outlook bodes well for his role in the future rotation.
Meanwhile, the emergence of dynamic prospects like Cole Carrigg adds to the franchise’s optimistic outlook. Their blend of youthful energy and refining skills offers a glimpse of the Rockies’ evolving roster, with speed and versatility playing pivotal roles.
As the Cactus League progresses, fans and analysts will closely watch how these pitching adjustments and prospect contributions translate into sustained success during the regular season.
