Guardians Shop Local, Extend Tanner Bibee
The latest excellent Cleveland starter is here to stay - contractually speaking.


The week leading up to Opening Day is extension season. Players want to put aside money discussions when the games start to matter, teams crave cost certainty, and everyone’s packing up from spring training with hope in their hearts; it’s a perfect setting for agreeing to deals. Amid a flurry of other activity, the Cleveland Guardians got in on the act by signing Tanner Bibee to a five-year, $48.5 million extension, with a club option for another year after that.
Let’s get straight to what you came here for, the ZiPS projections:
Year | W | L | ERA | G | GS | IP | H | ER | HR | BB | SO | ERA+ | WAR | $ | Status |
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
2025 | 10 | 8 | 3.48 | 29 | 29 | 160.3 | 141 | 62 | 20 | 45 | 163 | 120 | 3.0 | $0.8M | PRE |
2026 | 10 | 7 | 3.43 | 28 | 28 | 154.7 | 137 | 59 | 19 | 42 | 154 | 122 | 2.9 | $4.2M | ARB1 |
2027 | 10 | 7 | 3.50 | 27 | 27 | 151.7 | 136 | 59 | 19 | 40 | 148 | 119 | 2.8 | $7.5M | ARB2 |
2028 | 9 | 8 | 3.58 | 27 | 27 | 146.0 | 132 | 58 | 18 | 38 | 139 | 117 | 2.6 | $10.7M | ARB3 |
2029 | 9 | 7 | 3.59 | 27 | 27 | 145.3 | 133 | 58 | 18 | 38 | 134 | 116 | 2.5 | $23.4M | FA |
Those are pretty much what I expected. Through two years in the big leagues, Bibee has been a steady contributor whose best skill is good command. ZiPS projects more of the same for the next five years. That slight decline in innings you see over the course of the projection isn’t really a Bibee thing, it’s a pitcher thing. You just never know when one awkward elbow twinge will cost someone a year, and that’s reflected in declining innings totals over time.
Let’s talk about Bibee the pitcher for a moment before getting into the Guardians. He’s a product of the organization in the Shane Bieber mold, a crafty college arm who added velocity in the Cleveland system and went from fifth-round draft pick to runner-up for the 2023 AL Rookie of the Year award. That velocity doesn’t give him an unhittable fastball or anything like that. But where his fastball was a key sticking point in his pre-professional profile, now it’s just another average pitch. It sits 94-95 mph, touches the upper 90s in big spots, and has decent shape — more rise than run, but not a ton of movement overall.
That might not sound intriguing to you; after all, plenty of major leaguers have fastballs like that. But that’s the revelation here. With a boring fastball, Bibee’s other pitches all play up. He has impeccable command of spinning stuff, to the point where his pitches sometimes bleed together in our classification systems. There’s the hard one, either a cutter or sharp slider depending on who you ask, mid-80s and biting hard glove side. That’s his workhorse pitch, the one he favors in key spots and uses to set up strikeouts. There’s the sweepier version, a few miles an hour slower but with much more horizontal movement. He throws that one as a putaway pitch. Then there’s the curveball, slower still and with big north-south movement. He uses that as a change of pace, only when ahead in the count and largely fishing for strikeouts. The three combine to leave batters off balance and lunging.
That blended breaking ball complex looks a lot like Bieber, who followed a similar trajectory to the majors but then rode it even higher, to the 2020 Cy Young. Like Bieber, Bibee has a changeup to complement the bendy stuff. Bibee’s is loopy, 12 mph slower than his fastball, and most useful against lefties. His arm action disguises it enough that he can throw it to righties, too, and he’s willing to use it late in counts after batters have seen mostly fastballs and sliders.
As was the case with Bibee’s fastball, lots of major league pitchers have pitches that vaguely sound like the secondary stuff that I just described. What sets Bibee apart is his placement of those pitches. His fastball lives up in the zone. He attacks the glove-side edge with his hard slider and mixes locations haphazardly with the loopier breaking balls, alternating between placing them for called strikes and trying to pick out a corner or bounce a curveball. His changeup consistently hits the arm-side edge of the plate. He barely walked anyone in the minors, and that has carried over even against major league hitters.
You’ve seen the ZiPS median forecasts. The upside outcomes? Those will come if Bibee takes the next step with his slider by using it proactively and creatively. I keep comparing him to Bieber because we’ve seen that this exact skill set can produce ace-level seasons if everything breaks right. Maybe Bibee will top out as a three-win true-talent pitcher, but the future is unknowable, and he has the tools to break out to an even higher level than he’s already displayed.
For the Guardians, that present talent level is already mighty valuable. They just made the playoffs with Bibee as their no. 1 starter. They’re one of four contenders in the AL Central this year, again with him as their best option in the rotation. It’s a poor starting rotation, if we’re being honest, but that only makes him more important. It’s not Bibee and a bunch of similar options; it’s Bibee and then a bunch of question marks. Despite only two years in the majors, he’s a rock of stability in a sea of uncertainty.
This contract extension buys out either one or two years of free agency, depending on the club option. The value is almost exactly in line with what he’d expect to make in arbitration, plus a reasonable rate for the free agency year(s). This isn’t some outrageous bargain; it’s just two sides agreeing to tamp down volatility.
You can imagine some ways that this deal could end up making Bibee a lot more money than he otherwise would’ve received. Mainly, that’d be because of a future injury: As a fifth-round pick, Bibee never received a huge signing bonus, and he wasn’t due to hit arbitration (and bigger salaries) until 2026. That means he would’ve earned a raise pending health, but “pending health” is a scary phrase for pitchers. By signing this deal, he removed that risk. Now, there are no possible outcomes where Bibee doesn’t end up rich for life.
The Guardians, on the other hand, are getting future cost certainty. Not so much in the arbitration years – the terms of his extension roughly match what ZiPS would expect for those payouts. But let’s put it this way: The Guardians don’t sign big deals in free agency. They haven’t signed a marquee free agent on the open market in 20 years, since they added peak Kevin Millwood before the 2005 season. Those two years of free agency represent something the Guardians have no other way of obtaining – extra team control of very good players.
The Cleveland model has been remarkably successful for a long time now. It’s about constantly remaking the team even while the current version excels, finding new key players to replace the old key players while José Ramírez keeps the tempo. The Guardians deal in two currencies: talent and years. They’re adept at finding talent. Their budget and approach limit them on the years side of things.
In other words, Cleveland is always balancing competing now with competing in the future, and the limiting factor is usually how many years of good players the team has in hand. This extension addresses that directly by adding to the number of years that Bibee will be around, and adding in a way that the franchise can stomach financially. This deal won’t make the Guardians better in 2025, and it won’t even save them money in the immediate future. But now they have one more good player for at least one more year, at a price that makes sense for both sides. They’re in the business of sustainability, and this deal is perfect for their purposes.
