Bibee vs. Lorenzen: Fullerton's Alumni Weekend in Cleveland

Cal State Fullerton sent two of its own to the same series last week — and neither had much to brag about afterward.

Tanner Bibee took the mound for Cleveland in Thursday's rubber match against Toronto, and the results were strange enough to earn a footnote in the record books — though not a flattering one. Bibee's line through four innings — 4 IP, 4 K, 5 earned runs — produced a specific stat combination that hadn't been recorded since 1973, according to Heavy Sports. It wasn't historically great. It was historically odd, a distinction that about sums up Bibee's season as a whole. The right-hander's ERA sat at 4.06 after the outing, a number that tells the story of a pitcher capable of flashing genuine stuff while occasionally unraveling without warning.

On the other side of the diamond — literally — was fellow Titan Michael Lorenzen, pitching out of Toronto's bullpen. Lorenzen had appeared earlier in the series on Tuesday, working one inning and allowing two earned runs, a cameo that pushed his ERA to 7.13. He didn't factor into the rubber match, but the narrative writes itself: two Fullerton alums, same series, different uniforms, both searching for answers.

Lorenzen then turned up again Saturday as Toronto handled Kansas City 9-2. He threw three innings, struck out two, and surrendered one earned run — a modest step in the right direction, though his ERA barely budged, settling at 7.03. It's been a rough stretch for the veteran, who has now allowed runs in multiple appearances this week.

The Bigger Picture

The Bibee-Lorenzen overlap is the kind of quirk that alumni networks love — two guys from the same Fullerton program facing off at the highest level of the sport. But beyond the novelty, both players are navigating genuinely difficult moments in their 2026 campaigns.

Bibee, still only in his mid-20s, has the profile of a legitimate rotation piece. His strikeout rate against Toronto (4 Ks in 4 innings) isn't alarming, but the five earned runs signal that his command or sequencing broke down at a critical point. Cleveland will need him sharp down the stretch if they're chasing anything meaningful in September.

Lorenzen's situation is more pressing. A 7.03 ERA out of the bullpen is the kind of number that invites roster decisions. The Blue Jays gave him three innings Saturday, which could signal an attempt to stretch him out or simply a byproduct of a lopsided game — either way, continued struggles will test Toronto's patience.

For Fullerton fans, the week offered something rare and worth savoring regardless of the outcomes: two Titans on opposite sides of a major-league series, carrying the same program's name into a September that still has plenty of story left to tell.

Cal State Fullerton is having a week in the American League. Michael Lorenzen has a new home in Toronto, and Tanner Bibee keeps reminding Cleveland why he's one of the most reliable arms in the Guardians' rotation. Two Titans, two very different storylines — both worth watching as the playoff stretch run heats up.

Lorenzen Gets His Shot with the Blue Jays

The Blue Jays, battered by pitcher injuries, turned to a familiar solution: sign a veteran who can eat innings and provide stability. That veteran is Michael Lorenzen, the former first-round pick and Cal State Fullerton product who has bounced around the league in recent years.

Toronto signed the recently-DFA'd right-hander to bolster a rotation that has been held together with duct tape and prayers. Lorenzen made his debut in Blue Jays blue against the Royals on August 27th, throwing two innings, striking out two, and allowing one earned run — modest numbers for a pitcher working his way back into a major league role, but useful in an emergency.

His ERA sits at 7.04, reflecting the turbulence of his season to date. Still, the Blue Jays are clearly betting on the version of Lorenzen who can be a credible big-league arm, not just a roster filler. Whether he can lower that number and carve out a meaningful role in Toronto's crunch-time push remains the question.

Bibee Is the Guardians' Constant

While Lorenzen is finding his footing, Tanner Bibee is doing exactly what Cleveland needs from its rotation every fifth day: showing up and competing.

On August 23rd against the Rockies, Bibee tossed six innings, struck out six, and allowed two earned runs in a 4-3 Guardians win — the kind of quality start that keeps a team in the wild card race. Then, five days later against the Royals on August 28th, he went right back out and delivered another six innings, this time surrendering just one earned run while striking out five.

Back-to-back six-inning outings. Back-to-back quality starts. His ERA has ticked down from 3.97 to 3.88 over the week, a small but telling sign of a pitcher operating in control of his craft. Bibee isn't dominating highlight reels, but he's doing something arguably more valuable: giving Cleveland's bullpen rest and giving the lineup a chance to win every time he takes the ball.

The Guardians edged the Rockies 4-3 in that Sunday matinee, with Bibee's durability proving the difference in a tight contest that could have spiraled without a starter who could go deep.

---

For Fullerton faithful, it's a week that captures the breadth of what Titan baseball produces: a grizzled veteran fighting for a roster spot in a pennant race, and a 25-year-old homegrown starter quietly building a case as one of the AL's better young pitchers. Both wearing different uniforms, both carrying the same pitching-factory pedigree.

The week's biggest news for Titan alumni came not from the box scores but from the transaction wire, where Michael Lorenzen's time in Colorado came to an unceremonious end.

Lorenzen Designated for Assignment

The Rockies designated Lorenzen for assignment this week, recalling right-hander TJ Shook in the corresponding move. The transaction signals Colorado is no longer in win-now mode — not that the standings left much doubt — and is actively reshaping its roster with an eye toward 2027. For Lorenzen, the DFA effectively closes the book on his Rockies tenure. The veteran right-hander, who has carved out a lengthy career as both a starter and reliever, will now either clear waivers and accept an assignment or become a free agent, opening the door for a potential late-season lifeline elsewhere. At 34, Lorenzen still has the versatility to attract interest, but a Coors Field stint is not exactly the resume booster a pitcher markets himself on.

Bibee Takes the Hill in Cleveland

On the mound in more stable circumstances, Tanner Bibee started for the Guardians against San Diego on Sunday, Aug. 16. The results were mixed. Bibee went six innings, striking out three while allowing three earned runs — a serviceable but unspectacular line that left the door open for the Padres' offense. His ERA settled at 4.01 on the day. Yahoo Sports' MLB analysts had flagged the matchup as a tough one for Cleveland heading into the game, and Bibee's outing did little to dispel that concern.

Bibee continues to be one of the more quietly reliable Fullerton products in the big leagues — not a flashy name, but a consistent presence in a competitive rotation. Whether Cleveland's bullpen could hold the line after his exit was another matter.

The Bigger Picture

Cal State Fullerton's MLB footprint remains impressively wide for a mid-major program. From Bibee anchoring a playoff-contending rotation in Cleveland to veterans like Justin Turner (Cubs), Matt Chapman (Giants), and J.D. Davis (Angels) still contributing across the league, the Titans continue to punch well above their recruiting profile.

But Lorenzen's DFA is a reminder that the shelf life at the top is unforgiving. Few alumni careers have been as durable or as interesting as his — a two-way experiment, multiple team stops, playoff appearances. The next chapter is unwritten, but it won't be in purple and black.
