There were moments last season when I cringed when Antonio Senzatela was on the mound.
Too often, he’d throw his 95-mph fastball over the heart of the plate. “Thwack!” Baseballs sizzled off the bat. Full Charlie Brown mode. Duck and cover. It was hard to watch.
Opponents had a .352 batting average against Senzatela’s fastball. It was one of the most hittable pitches in the majors. He posted a 6.65 ERA and served up a career-high 22 home runs. In 108 innings as a starter, Senzatela posted a 7.48 ERA and 1.91 WHIP. Manager Warren Schaeffer was forced to demote him to the bullpen as a cleanup reliever.
“Senza,” as everyone calls the Rockies’ veteran right-hander, has never come close to being a star, but he was a serviceable back-of-the-rotation pitcher. But, in retrospect, it seemed like a mistake to sign him to a five-year, $50.5 million contract extension in October 2021.
He’s been through a lot. He sustained a torn ACL in August 2021, worked his way back, blew out his elbow, and underwent Tommy John surgery in July 2023. Through it all, Senzatela has been a complete pro. He’s beloved by his teammates and is always friendly with the media. Most of all, he put in the work.
But Senza looked done. The $12 million he’s making this season looked like dead money.
But now, he’s one of baseball’s best stories in the early going. How many pitchers reinvent themselves at 31?
Entering the weekend, he had yet to give up a run over five games (12 1/3) innings as a long reliever. His 0.568 WHIP is ridiculously low. He’s struck out 15 and walked just three.
Schaeffer never gave up on Senzatela, but knew the right-hander had to change if he wanted to thrive as a long reliever under the Rockies’ new game plan, in which long relievers play a critical role.
“One hundred percent, he could have gone one of two ways — the other way or the way he’s going now — which is a credit to the way he went about it,” Schaeffer told MLB.com in San Diego last weekend. “None of us doubted that this was going to be the case. I’m extremely proud of the way he goes about his business, attacking it every single day.”
During the offseason, Senzatela trained at Push Performance, a Phoenix-area training facility. Under the tutelage of new Rockies pitching coach Alon Leichman and new assistant pitching coach Gabe Ribas, Senzatela honed his craft during spring training. He experimented with different grips, adjusted his position on the pitching rubber, and changed his mentality on the mound.
Now, Senza looks like a different pitcher. His average four-seam fastball velocity has increased from 95 mph to 97.2 mph. More importantly, he’s become a less predictable pitcher. Last season, he threw his four-seam fastball 59.6% of the time. This season, he’s using it 39.6% of the time,
Last season, he threw his cutter 1.8% of the time. This season it’s up to 26.6%. Senzatela’s slider, a pitch he’s never commanded particularly well, has been put in the back pocket (18% in 2025, 3% in ’26). He threw a sinking fastball hardly at all last season (0.5%), but he’s throwing it at 95.9 mph this season (12.4%) and getting groundball outs with it.
Senza said that once he made adjustments to his pitcher repertoire and his daily routine, he’s come to like coming out of the bullpen.
“I feel really good,” he said Friday before the Rockies hosted the Dodgers. “I can feel my adrenaline when I come into a game. So it feels really good (coming out) of the bullpen and having that experience.
“It’s different knowing you have to be ready almost every day. Itap different for me now, but itap going good.”
Actually, better than good. In April, he’s been praise-worthy, not cringe-worthy. Good for him.
