The Giants promoted Matt ‘Tugboat’ Wilkinson, who has a chance to be a fan favorite

At the beginning of March, when the World Baseball Classic was just starting, a Canadian player caught my attention. His name was Matt Wilkinson, and his nickname was “Tugboat.” As a self-appointed baseball-nicknameologist, I can confidently state that this a lousy era for nicknames, but Tugboat gave me hope. It’s a nickname that could fit in any era, any decade.

It was the picture that completed the whole package, though. It was the image of a pitcher working hard, steadfast and determined, a workhorse capable of pulling his entire team behind him. Hence the nickname, “Tugboat.” He also kinda looked like a tugboat. So even before I knew that Wilkinson was a Cleveland Guardians prospect, I proclaimed my fealty.

The fates were kind after that, and Wilkinson was traded to the Giants a part of the return for Patrick Bailey. A lot of Giants fans remember rooting for characters like The Caveman and Big Daddy, and they deserve the chance to root for a Tugboat.

That day has arrived. Wilkinson was called up on Monday, and he’ll likely make his debut against the Cleveland Guardians, his original organization. Is this the beginning of a new era, or are we already most of the way through an amusing footnote in Giants history? Here’s a quick explainer on what to expect.

What makes Tugboat unique

Wilkinson isn’t just a throwback to the Giants’ starters from the late 1980s because of a colorful nickname. His fastball velocity is also from the ‘80s. Which means it’s often in the 80s. There’s deception in his game, and a changeup that pairs well with the fastball and plus command, but success with this kind of left-handed profile is still somewhat rare, at least in the rotation. Of the 17 qualified left-handed starters this season, the lowest average four-seam fastball was still 91.5 mph, while Wilkinson’s average four-seamer in Triple A was 89.9 mph.

However, there’s a twist to this situation. The classic lefty throws fastballs as a way to set up their offspeed stuff, with a lot of them traditionally pitching backward. Wilkinson, though, pumps his fastball over and over again like a closer. He threw his four-seamer with 62 percent of his pitches, fourth among all minor leaguers who had more than 100 pitches tracked in Statcast. His fastball usage was just above that of Gage Wood, a Phillies prospect who throws in the mid- to upper-90s, and Wilkinson’s whiff rate on the pitch (22.9 percent) was almost exactly the league average for four-seam fastballs. He’s not ashamed of his fastball. It’s how he got to the majors.

Even the best examples of crafty lefties typically include some years of struggle at the beginning. And when Wilkinson throws a slowball that gets hit a long, long way, it’ll have that Tyler Rogers-kind of feel, where you watch a batter whomp a sub-90s fastball extremely far and it makes perfect sense. What do you expect from a fastball like that?

The odds are against Tugboat, if only because they’re against every lefty with his profile, and it’s possible that he’ll never be a major-league starter or reliever. On the other hand, he’s a starting pitcher on the 40-man roster and in the upper levels of the minors. If he pitches well, he’s in an organization that has an acute need for someone just like him. A “good pitcher,” if you can imagine such a thing.

Why now?

Wilkinson started the season in Double A in the Guardians’ system, and he pitched well over six starts there (1.59 ERA), before also pitching well at the same level in the Giants’ system after the trade (three starts, 2.40 ERA). He scuffled a bit in Triple A, though, with a 5.15 ERA and a slight bump in his walk rate that you might expect from a pitcher who needs to be even more fine with his command. These are Ryan Vogelsong-flavored walks from a pitcher who can throw strikes at will, but also knows he can’t. They probably won’t stop at the highest level, which is to say that Wilkinson didn’t exactly force his way into a promotion.

’Tis the season, however, to gather information. Everything the Giants do from now until the end of the year should inform how they attack the offseason and build a roster for 2027. Each starter who does or doesn’t prove himself in the majors will change how the organization allocates its resources.

More than any of this, though, is that we can reference Kirk Rueter and Yusmeiro Petit and yak about other low-velocity names from the past, but none of it tells us how this specific prospect will perform as a starter in the majors. The most advance statistical analyses couldn’t tell you with any certainty, either. The only data that matters will be how comfortable major-league hitters look against his deceptive fastball. It’s his best pitch, after all. And if major-leaguers thrive against it right away, that’s extremely helpful information.

If hitters struggle against Wilkinson’s fastball the first time through the order, but not the second, that’s also helpful information. If it ticks up coming out of the bullpen, that’s also helpful to know. Or, perhaps, the jump from Triple-A fielding (and fields) to the majors is exactly what he needs to resume his lower-minors dominance. The Giants will have a good sense, with all of the available data, how comfortable or uncomfortable he’s making hitters.

This sort of info is helpful for every organization in a lost season, but the Giants are going to have a clear mandate to rebuild the rotation, and they’ll likely have at least one internal competition for a spot, if not two. This is “Spring Training: The Prequel”, in other words. Except it’s happening in games that count, which seems like a much better way to glean information.

Forecast for next season

First, a mea culpa: I wrote last week that a lack of attention to the waiver wire led to “unexpected spot starters,” and it was pointed out that that couldn’t be further from the truth. The Giants have used just nine starters this year, with one of them being JT Brubaker as an opener. The other three starters the Giants used apart from the rotation on Opening Day were Trevor McDonald, Carson Whisenhunt and Blade Tidwell — all from within the organization. This is a historically low number of starting pitchers, so strike that one from the record.

The last three pitchers mentioned, however, McDonald (who has since undergone Tommy John surgery), Whisenhunt and Tidwell, all fit together as an example of what the organization has been working with. It’s a wide collection of different styles, with all of the pitchers throwing well enough to make you feel like they’re One Weird Trick away from becoming rotation mainstays … while consistently getting discouraging results. You can add Tristan Beck and Carson Seymour to the pack, even if they’ve already shifted into more of a relief role. The system has a minor glut of pitchers whose future might be in the bullpen, and Wilkinson adds to that kind of bittersweet depth.

If the Giants can at least feel half-good with filling just one rotation spot internally, alongside Logan Webb and Landon Roupp, it’ll make the offseason more bearable for the front office and fan base alike.

Now forget all about the above, and get ready for a player named Tugboat. You’ve always been ready for a player named Tugboat, but you just didn’t know it. With any luck, he’ll help the Giants get back to port at McCovey Cove after being lost all season. That sort of thing is what tugboats are built for, after all.
