2026 Fantasy Outlook
Kay owns a career 5.59 ERA and 1.61 WHIP in 85.1 MLB innings in a swingman role, yet the White Sox signed him to a two-year, $12 million deal in December and appear set to give him a spot near the front of their rotation. That comes after the lefty's two-year stint in Japan, although it was really only 2025 where Kay had much success, with his ERA dropping from 3.42 to 1.74 and his WHIP falling from 1.34 to 0.98. His 21.5 K% last season was actually lower than his career MLB mark of 22.4%, but his 6.8 BB% was miles better than his 12.0 BB% from his time in the majors. He also had a groundball rate north of 50% after sitting around league average in that category when we last saw him stateside. He's going to need the control improvements and groundball ability to carry over if he's going to have success in the big leagues this time around given his relative lack of whiffs. It's an innings-eater profile for a team that won't win many games, giving Kay low upside in most fantasy leagues. Read Past Outlooks
Signed a two-year, $12 million contract with the White Sox in December of 2025. Contract includes $10 million mutual option for 2028.
Picks up fourth win Monday
Kay (4-1) earned the win Monday against the Twins, allowing one run on five hits and one walk with five strikeouts across six innings.
Analysis
Kay's lone blemish was a solo homer allowed to Brooks Lee on just his fourth pitch of the game. After entering May with a 6.12 ERA, Kay has allowed two earned runs or fewer in all five starts this month and has posted his two quality starts of 2026 over his last three outings. The left-hander has shown above average stuff (105 Stuff+), including a very good sinker, slider and changeup trio, and has lowered his season ERA to 3.96 with a 39:23 K:BB across 52.1 innings. His 16 percent strikeout rate is in just the 12th percentile.

Past Fantasy Outlooks
2021
2020
A starter throughout his minor-league career, Kay broke summer camp on the Blue Jays' 30-man roster. He was expected to play a swingman role but ended up pitching exclusively out of the bullpen, making 13 appearances in relief before being optioned to the team's alternate training site in mid-September. Kay was never comfortable as a reliever, walking 14 while allowing three homers in 21 innings, though he did fan 22 batters. Toronto has opened its window to win and taken measures to strengthen the rotation, so Kay's future may be in a similar bullpen role, which doesn't lend itself to fantasy. To get back in the rotation mix, he needs to work on command and control, but with average stuff, his ceiling is capped as an innings eater. Kay is probably better off focusing on a couple offerings to maximize his effectiveness as a reliever.

Latest Fantasy Rumors
Rotation opportunity on tap?
Kay is a candidate to slide into the Blue Jays' starting rotation as a result of Chase Anderson's placement on the injured list due to an oblique injury.
Analysis
Kay saw major-league action last season, making three appearances, including two starts, and posting a 1-0 record, 5.79 ERA and 1.43 WHIP over 14 innings. The young southpaw had an uneven minor-league career, but his 2.50 ERA over 36 innings at Triple-A Buffalo prior to last year's promotion supports the notion he could hold down the fort for a handful of outings before Anderson returns. In addition to Kay, manager Charlie Montoyo could opt to turn to Ryan Borucki, who's produced mixed results over his first pair of big-league stints the last two seasons.
