The Toronto Blue Jays are looking to bolster their starting pitching depth.
Williams, 28, owns a 3.70 ERA and 4.21 FIP over 24 1/3 innings while making five starts this year. The right-hander is under team control through 2022 after hitting arbitration for the first time this past winter.
Kuhl has been relied upon as a swingman for the Pirates, making three starts and two relief appearances while posting a 2.84 ERA and 4.98 FIP in 19 innings. The 27-year-old also became eligible for arbitration this past winter and is under team control through 2022.
Entering Monday, the third-place Blue Jays had the 21st-ranked starting staff, according to FanGraphs WAR, collectively owning a 4.68 ERA and 5.10 FIP. Seven different pitchers have made at least one start for the Jays through 27 games.
The 2020 MLB trade deadline is Aug. 31.
