The Roster Move That Started It All
The week's biggest UL Lafayette storyline began in Toronto. The Blue Jays designated left-hander Joe Mantiply for assignment and optioned right-hander Spencer Arrighetti to Triple-A Buffalo — both moves made to clear roster space for the returns of Trey Yesavage and Chad Dallas. For Mantiply, the DFA marks a sobering end to his time in Toronto. For Arrighetti, it's a short-term demotion that still stings with the regular season winding down.
Arrighetti's final outing of the week didn't help his case. On September 20 against Texas, he lasted just 2.1 innings, allowing 2 earned runs while striking out 2 — leaving his ERA at 4.96 on the season. The Blue Jays' decision followed the very next day.
Brandon Young Quietly Makes a Case in Baltimore
While the roster drama unfolded in Canada, Brandon Young was quietly putting together one of the stronger two-start stretches of any Cajun arm this week in Baltimore.
On September 20 against Milwaukee, Young went six innings, struck out nine, and surrendered just 2 earned runs. Five days later against the Yankees — in what Yahoo Sports framed as a marquee Game 161 matchup — he was even better: 5 innings, 6 strikeouts, 1 earned run, with his ERA settling at 3.56. For a Red Sox pitching staff navigating the final days of a long season, Young has been a reliable presence, and his two-start week quietly stands as the Cajuns' best individual performance of the period.
Hogan Harris Holds Down the Pen in Oakland
Out west, Hogan Harris continued his steady late-season role in the Athletics' bullpen, appearing in three consecutive series games against the Angels and Astros. He worked exactly one inning in each outing, posting a strikeout in all three appearances. He did surrender a run against the Angels on September 23, nudging his ERA slightly, but responded with a clean frame the following day. By Saturday against Houston, his ERA had settled at 3.33 — a respectable number for a reliever logging regular work in a competitive Western Division race.
Harris hasn't been flashy, but three appearances in four days tells you the A's trust him when it matters.
The Bigger Picture
Four Cajun arms made meaningful contributions — or headlines — in a single week of the 2026 MLB season. That's not an accident. UL Lafayette has built a pitching pipeline that now runs from Toronto to Baltimore to Oakland, and this week illustrated both the opportunity and the volatility of life at the big-league level. Mantiply's DFA is a reminder of how fast things change; Young's back-to-back quality starts are a reminder of why teams keep going back to Lafayette when they need arms.
With the postseason picture coming into focus across baseball, the Ragin' Cajuns still have pitchers on rosters that matter.
