The Kansas City Royals have continued to find ways to strengthen the bullpen. Carlos Estevez, who made his Royals debut in 2025, has emerged as the leader of the relief core. Estevez earned his second career All-Star selection during the '25 campaign and ultimately led the league in saves with a mark of 42.
It was a tremendous season to say the least. So, how did Estevez find success in Kansas City?
Estevez kept hitters off balance all year, holding opponents to a .199 batting average. He also allowed only five home runs, holding hitters to a career-best 1.9 percent home run rate. Estevez's 20.1 percent strikeout rate was below his career average, but he found success nonetheless by limiting hard contact and keeping the ball in the ball park. In fact, his 38.1 percent hard-hit rate against was also a career-best mark.
He throws three pitches overall, including a fastball, slider and changeup. Estevez primarily leans on his fastball -- which he throws over 50 percent of the time -- and slider -- which he throws over 30 percent of the time.
Estevez does not necessarily do anything on the mound that especially stands out, but he throws enough strikes to keep hitters guessing. He understands what it requires to close out games, and his 2025 performance perfectly displayed his poise on the mound.
A few more strikeouts would be nice, but 2025 was a strong season for Estevez. He has become one of the best right-handed relievers in the sport.
As long as he can stay healthy, there is reason to believe that Estevez will pitch at a high level once again. The 33-year-old may have even more motivation to pitch well during the '26 campaign, as it could be a contract year for him. However, his contract does include a club option for 2027, so the Royals will probably exercise the option if Estevez performs well once again.
There is also a chance that Estevez will get to pitch in the playoffs this year, as Kansas City is building a contending roster. His postseason experience is rather limited, as he has pitched in MLB since 2016 but has made the playoffs in only two of those years.
Estevez has pitched to a 6.00 ERA across four total postseason appearances, so it would be interesting to see how he performs under the bright lights of October should the Royals clinch a playoff appearance.
