Mitch White was back on the mound for the Buffalo Bisons on Saturday, but things flew off the rails quickly in his fifth rehab appearance at triple-A.

The 28-year-old right-hander, whose rehab assignment was paused briefly due to shoulder fatigue, received the starting nod in Saturday’s contest versus the Lehigh Valley IronPigs – the Philadelphia Phillies’ triple-A affiliate. His first start in almost three weeks, however, didn’t last very long.

White surrendered five runs – all earned – on five hits, two walks and a hit by pitch while striking out four batters across just 2.1 innings. The 6-foot-3 hurler’s biggest hiccup came in the second, allowing three consecutive hitters to reach base before being tagged with a three-run blast by Jake Cave, leading to a four-run inning.

Despite recording his fourth punchout to begin the third, White was pulled from the game after giving up Jim Haley’s 109.5-m.p.h. double, capping another disappointing performance. And as you can see below, the struggling righty failed to control the strike zone all game.

White leaned heavily on his four-seamer, throwing it over 50 per cent of the time, but it generated zero swinging strikes on 15 swings. Opposing hitters also created a 99.5 m.p.h. average exit velocity against it.

The former Los Angeles Dodger’s sweeper – a slider that features sharp horizontal break – displayed promise at times, though, inducing five whiffs on eight swings. But there were also instances where it struggled to miss barrels.

The Blue Jays, who transferred White to the 60-day IL last week, received a fresh 30-day clock once his rehab assignment resumed and have until June 25 before needing to determine his next steps.

White is currently out of minor-league options and would require waivers if he isn’t returned to the majors after his 30-day clock expires.
