Royals Sign Helcris Olivarez to Minor League Deal

On Wednesday morning, Red Sox insider Ari Alexander reported that left-handed pitcher Helcris Olivarez agreed to a Minor League deal with the Royals that includes an invitation to Spring Training.

Olivarez started his career as a pretty heralded prospect in the Rockies' system with high-velocity stuff. However, he suffered a shoulder injury in 2022 that required surgery. Recovery forced him to miss the remainder of 2022 and all of 2023. Olivarez was later released by the Rockies and was picked up by the Red Sox before the 2024 season. He spent half a season with the Red Sox before being let go in July of that season. The Giants promptly picked him up after his release and primarily pitched the remainder of the season in Double-A Richmond. He spent all of last season in the San Francisco organization, pitching in Richmond and Triple-A Sacramento.

With the Rivercats last season, he posted a 3.65 ERA and 1.62 WHIP in 37 IP (34 appearances). He posted impressive strikeout numbers (26.3% K rate) and a solid CSW (30.2%). Unfortunately, he struggled with control, as illustrated by his 24.6% walk rate and 1.7% K-BB%. As a result, his FIP was 5.84, 2.19 points higher than his ERA. 

The 25-year-old lefty possesses solid stuff, though he doesn't quite have the 100-MPH stuff that he once had as a Rockies prospect. According to TJ Stats, he posted strong TJ Stuff+ metrics and encouraging whiff rates, as shown below.

Olivarez's overall TJ Stuff+ was 101. He also sported two pitches with 64 grades: the sinker and changeup. His whiff rate was 37.3% and his xwOBACON was .277. That showed that Olivarez in Triple-A could not just generate swings and misses, but also unproductive contact.

Unfortunately, his paltry 40.2% zone rate and lackluster 18.8% chase rate weigh down his overall outlook at the Major League level. It will be hard for him to succeed until he improves his control and reduces the number of free passes. 

The Royals likely view Olivarez as a project who will likely eat a lot of innings as the primary lefty reliever in the Triple-A Storm Chasers bullpen. According to Roster Resource, the only other lefty relievers currently in the Omaha bullpen are Chazz Martinez and Christian Chamberlain, who are both older than Olivarez. That said, the Royals have had success the past couple of seasons with relievers on Minor League deals, as demonstrated by Taylor Clarke last year and Sam Long in 2024.
