The Expense of a Trade: What the Blue Jays Gave Up in Khal Stephen

The Toronto Blue Jays made a monster but risky move to bolster their starting rotation by acquiring Shane Bieber from the Cleveland Guardians. Bieber hasn't thrown a pitch in the major leagues all season, as he is recovering from Tommy John surgery he had in April 2024. The right-hander won the AL Cy Young Award in the 2020 pandemic-shortened season and became the 29th pitcher since 1913 to claim the Triple Crown, leading the majors in wins (8), ERA (1.63), and strikeouts (122).

This season, he has thrown 11 innings over four rehab starts for three different minor league affiliates. The 30-year-old has been impressive, pitching to a 1.59 ERA and a 22:2 strikeout-to-walk ratio, and limiting hitters to a .179 batting average. Acquiring the former ace came at a high cost, though. The Blue Jays had to part with Jays Centre's no. 5 prospect, Khal Stephen.

Stephen was drafted in the second round in 2024, 59th overall, out of Mississippi State. In that season, he pitched 96 innings, posting a 3.28 ERA with a 107:27 strikeout-to-walk ratio, and opponents hit .213 off the righty. In Stephen's first minor league season, he has been outstanding. Between Single A, High A, and Double A, he has started 17 games with a 9-1 record, 2.06 ERA, and 99:20 strikeout-to-walk ratio, and batters have hit .196 off of him. Plus, he has one save from his only non-start appearance.

The 22-year-old was charging through the Blue Jays' minor-league system, and FanGraphs listed him as their 80th overall prospect in their pre-trade deadline rankings. The 6-foot-4, 215-pound pitcher throws a fastball at 92-94 mph and can top out at 96. The movement on his fastball is what has scouts salivating. Stephen has struck out 9.72 batters per nine innings and has found the ability to leave runners stranded on base when they get on, with a 78% left-on-base percentage.

Stephen's best offspeed pitch is his mid-80s changeup, but he also has a slider, cutter, and curveball to fill out an impressive pitching arsenal. He slots in as the Guardians' no. 7 prospect (per MLB Pipeline) but is the top pitcher in their system. His slider and curveball will need improvements to build out an MLB-ready arsenal, but if the righty continues to perform at this level, then we can expect to see him in the big leagues within the next two seasons.

The Blue Jays needed to add a starting pitcher at the trade deadline, and they paid a high price to obtain one. For a rental, the Blue Jays gave up an arm who has the potential to be a future star. General manager Ross Atkins took a massive swing for the fences, so we will have to see how this plays out over the next few years. That said, if the Commissioner's Trophy finds its way to Toronto at the end of the season, then the risky move will have been well worth it.
