Tyler Ferguson: Everything you need to know

The Athletics optioned Ferguson to Triple-A Las Vegas on Friday. Ferguson was one of the A's most used relievers in 2025, making 56 appearances and throwing 58.0 innings. However, he'll be sent down to the minors before Opening Day. Ferguson posted a 6.00 ERA, a 1.83 WHIP and a 6:2 K:BB across six innings this spring.

Ferguson threw two perfect innings while striking out two and earned a hold in Tuesday's 5-1 victory over the Astros. Ferguson was sharp Tuesday, retiring all six batters he faced in his first two-inning outing since May 21. The right-hander has been solid in September, posting a 2.89 ERA and 0.75 WHIP across eight appearances and 9.1 innings. His season line of a 4.79 ERA and 1.33 WHIP in 54 outings and 56.1 innings looks rougher, but those numbers are heavily skewed by two blowup appearances on May 14 and June 18, when Ferguson combined to allow 11 runs.

Ferguson picked up the save in Wednesday's 4-2 extra-inning win over the Twins, allowing no hits and one walk with no strikeouts in a scoreless 10th inning. The save was Ferguson's second of the year and his first since way back on May 4 in Miami. The 31-year-old right-hander has rattled off 7.1 consecutive scoreless innings, though he likely still has work to do before the Athletics trust him in the high-leverage mix on a consistent basis following the Mason Miller trade. For the campaign, Ferguson has a 5.53 ERA, 1.44 WHIP and 41:29 K:BB over 42.1 innings.
