St. Joseph's Professional Athletes

Brett Callahan is getting a September education in the big leagues — and the St. Joseph's product is holding his own.

The rookie outfielder logged time in all seven of the Detroit Tigers' games during the week of Sept. 13–19, a stretch that saw the Tigers navigate a home series against the Colorado Rockies before hitting the road to face the Toronto Blue Jays and then closing out the week against the Chicago White Sox. Callahan's presence in the lineup was anything but guaranteed — Detroit made at least one "surprising" roster decision with him during the Rockies series, per Heavy Sports — but the Hawks alum kept finding his way onto the field.

The week's high-water mark came Monday, Sept. 14, when Callahan delivered a hit and an RBI in a 6–5 Tigers win over Toronto, bumping his average to .231. He also got on base via walk during the Blue Jays series — though Detroit dropped both of those games, including a lopsided 10–1 loss Tuesday. His bat went quiet through the middle of the week, but he picked up another hit Saturday against Chicago, finishing the week at .220.

Callahan also drew some individual attention during the Toronto series — not the kind he was hoping for. Sportsnet cameras caught Blue Jays reliever Jose Soriano flashing the leather on a sharp comebacker off Callahan's bat, a highlight that made the rounds as a defensive gem for Toronto.

The bigger roster picture around Callahan was fluid all week. The Tigers removed infielder Hao-Yu Lee from Monday's lineup due to injury before first pitch at Rogers Centre, bringing Gleyber Torres into the starting nine at second base alongside Callahan. Managing a September roster with one eye on the standings and another on player development is a familiar Tigers balancing act, and Callahan has remained part of that equation throughout.

No other St. Joseph's alumni appeared in notable game action or headlines during the period. Ryan Cesarini (Guardians), Andrew Cossetti (Twins), Brian O'Keefe (Mariners), Ryan Picollo (Mariners), Domenic Picone (Cardinals), and Hayden Seig (Angels) were all active in the league but did not generate coverage or standout stats this week.

For Callahan, the final weeks of a rookie season — roster shuffles, day-to-day lineup uncertainty, national TV moments on the wrong end of a highlight — are part of the tuition. He's still paying it, and still showing up.

Brett Callahan's name made headlines this week — but not for the reasons Hawks fans would prefer. The Detroit Tigers used the left fielder as the backdrop for a roster announcement that came in the middle of one of the ugliest series collapses of their season.

The Series Implosion

Detroit's three-game set against Minnesota was a disaster from the jump. The Tigers dropped Game 1 by a score of 11-1, then found a way to be even worse in Game 2, surrendering a 15-2 beatdown to the Twins. Back-to-back blowouts of that magnitude forced the Tigers' front office to act, and Callahan — Detroit's starting left fielder — was connected to whatever moves followed.

The details of the announcement, made after Game 1 and again revisited following Game 2, center on roster maneuvering tied directly to Callahan's status on the team. Two separate Heavy Sports reports confirmed the Tigers made Callahan-related news on consecutive days of the series, signaling that the organization wasn't standing pat while Minnesota put up crooked numbers at will.

Callahan at the Plate

Whatever the roster turbulence meant for Callahan's role, his bat told a mixed story across the week. He collected a hit on Monday (Aug. 31) against the Twins, walking once as well, and added another hit Tuesday (Sept. 1) to push his average to .281 — his peak for the stretch. But his numbers slid in the days that followed: by Wednesday's series finale against Minnesota, he was hitting .265, and by the weekend's games against the Guardians, his average had settled at .257.

It's a modest retreat, but the context matters. Playing through a week in which his team was outscored 26-3 over two games — and amid front-office noise about his own roster situation — Callahan at least stayed in the lineup and put the ball in play when it counted.

The Bigger Picture

St. Joseph's doesn't produce MLB regulars in bunches, which makes Callahan's sustained presence in a Tigers lineup fighting for positioning in the AL this late in the season worth tracking. Detroit's series finale against Minnesota offered a chance to salvage something from a brutal homestand; the subsequent Guardians series gave Callahan two more cracks to stabilize his average heading into September's final stretch.

No other Hawks alumni had statistically notable weeks in the research window, though Ryan Cesarini (Guardians), Brian O'Keefe and Ryan Picollo (Mariners), Domenic Picone (Cardinals), Andrew Cossetti (Twins), and Hayden Seig (Angels) all remain active at the big-league level.

For now, Callahan is the story — and what the Tigers' announcement means for his role in Detroit's final month is the thread worth pulling.
