2026 review

Jonathan Loáisiga was a control-heavy setup piece who kept the ball in the park but never nailed down a steady closing role, going 7-3 with a 2.42 ERA and 1.03 WHIP in 67.0 IP, an 18.4 K% and a 5.0 BB% over 261 BF across 67 games for ARI, with 2 SV, 10 HLD and 4 BS. He signed a minor league contract Jan 12 and had his contract selected Mar 25. His 5.0 BB% over 261 BF was the 21st lowest of 517 pitchers with 100+ BF. Drafted at ADP rank 994 and taken in only 71 of 674 drafts, he finished 218th of 1472 overall in the TDK LABS 5x5 value rank and 33rd of 575 relievers. His 2.42 ERA ran 0.59 below his 3.01 xERA over 261 BF. Right-handed batters hit just .179/.203/.211 over 128 PA against him, while left-handed batters hit .286/.336/.437 over 133 PA. The TDK LABS card called him a blown-save-prone setup arm with no save path in early May, still fluid after a back-to-back blown save by late Jul, part of a muddled committee by mid-Aug, and by late Sep pointed to a pristine control profile.
