Luke Little was an afterthought when our 2023 Chicago Cubs Top Prospects list came out in early July. Pitching for Double-A Tennessee at the time, the now–23-year-old southpaw garnered no more than an honorable mention on a list that ran 52 players deep. His stock has since risen markedly. By season’s end, he had earned a big league cup of coffee and thrown 6.2 scoreless innings over seven appearances. Featuring a high-octane heater and a sweeper delivered from a low arm slot, he fanned a dozen batters and allowed just five hits.

His numbers across three levels of the minor leagues were every bit as impressive. Over 36 appearances, all but four as a reliever, the 2020 fourth-round pick out of San Jacinto College had 105 strikeouts and surrendered 40 hits in 63.2 innings. He’s an imposing figure on the mound: The Charlotte, North Carolina native stands 6-foot-8 and weighs 270 pounds.

Little discussed his repertoire and delivery prior to a late-September game at Wrigley Field.

David Laurila: Who are you on the mound? For instance, do you identify as a power pitcher?

Luke Little: “I like to think I’m a power pitcher. Obviously, I throw hard. At the same time, I like to think that I have good offspeed pitches. I’ve been really comfortable with my slider, and I’ve also got a good feel for my splitter now, although I haven’t thrown it too much.”

Laurila: How hard are you throwing?

Little: “Last night [September 19 against the Pirates], I sat 97 [mph] with my fastball, and my slider was 81–82. I was up to 99 with my fastball at the beginning of the year, [which is] the hardest I’ve ever thrown, when I was a starter [with High-A South Bend].” Read the rest of this entry »

Justin Steele has an uncommon pitch profile and an uncomplicated approach to his craft. He also has an outside chance of capturing this year’s NL Cy Young award. With two starts remaining (one if the Cubs clinch a Wild Card berth prior to Sunday’s regular-season finale), the 28-year-old southpaw is 16–5 with a 3.00 ERA and a 2.99 FIP over 168 innings. He’s not only been Chicago’s best pitcher, but he’s also been one of the best in the Senior Circuit.

Steele’s emergence as a frontline starter was portended by last year’s performance. While his won-lost record was an anything-but-eye-catching 4–7, his 3.18 ERA and his 3.20 FIP weren’t notably higher than this year’s marks. Moreover, his strikeout and ground-ball rates were actually better, as were his xFIP and HR/9. His BABIP was nearly identical. The only meaningful difference, on paper, was his walk rate, which at 3.78 was essentially double this season’s 1.88.

Prior to his last outing — a game in which he was BABIP’d to death by six consecutive fourth-inning singles — I approached Steele in Wrigley Field’s home clubhouse to get his thoughts on what has been an outstanding season. The following day, I asked Cubs pitching coach Tommy Hottovy about the pitch characteristics that make Steele a Cy Young contender.

———

David Laurila: Won-lost record and walk rate aside, a lot of your numbers aren’t all that different from last year’s. Are you more or less the same pitcher?

Justin Steele: “I would say that I’m better. The pitches are the same, I’m the same pitcher as far as that goes, but I’ve been more consistent this year. I’m not walking as many guys. I’m being competitive throughout the count, I’ve cut down on non-competitive pitches big time. So yeah, a lot more consistent.”

Laurila: Were you happy with last year?

Steele: “I think so. I was definitely happy with how I finished up [a 0.99 ERA over his last seven starts]. I felt like the entire season I was improving. That’s something that’s really important to me, always improving from start to start.”

Laurila: What’s behind this year’s improved consistency?

Steele: “I think it’s just more reps, getting more and more comfortable out there each time I take the ball. It’s like anything in life: you do it more and you get more comfortable doing it. You also get better at it.” Read the rest of this entry »

Hao-Yu Lee will be one of eight Detroit Tigers prospects participating in the forthcoming Arizona Fall League, and while he doesn’t possess the highest profile of the bunch, he does have the most-traveled backstory. Acquired from the Philadelphia Phillies at the trade deadline in exchange for Michael Lorenzen, the 20-year-old infielder hails from Taiwan and began dreaming of playing professionally in the United States at age 16 after a strong performance in a U-18 tournament, in Korea. Two years earlier he’d excelled in a tournament that took place 15-plus miles southwest of Comerica Park.

The Phillies signed Hao-Yu in June 2021—the Cincinnati Reds and Tampa Bay Rays were among the other MLB teams that had expressed interest — once he’d finished high school. No. 8 on our Phillies Top Prospects list with a 40+ FV coming into this season, he slashed .273/.362/.399 before going on the shelf with a quad strain in mid-August. He ended up playing in just eight games for the High-A West Michigan Whitecaps before missing the duration of the campaign.

The first big-league game Hao-Yu attended was in 2017 when he was competing in the Junior League World Series, which is held annually in Taylor, Michigan. He doesn’t remember if the Tigers won that day, but he does recall his first impression of Comerica Park. “I told my teammates that I was going to play here someday,” the confident youngster said of the experience.

He also remembers the tournament, and for good reason. Not only did Taoyuan, Taiwan capture the international bracket, they went on to beat Kennett Square, Pennsylvania in the finals. Moreover, Hao-Yu “raked that tournament; five games, five homers!” Read the rest of this entry »

I’ve been fascinated by the idea of mirror image twins since the Giants signed Taylor Rogers last December, pairing him up with his brother Tyler and illuminating me to their unusual genetic connection. As monozygotic (i.e., identical) twins, they come from the same fertilized ovum and, thus, the same DNA. Taylor, however, is left-handed, and Tyler is right-handed, a manifestation of their mirror image relationship.

Mirror image twinship makes for a perfect metaphor, and as a writer, nothing excites me more. It’s like a real-world example of a contronym, a word that can have two opposite meanings in different contexts; the word “dusting” always looks the same, but sometimes it means to remove dust, and other times it means to sprinkle it on. It’s the same thing with the Rogers twins. They look exactly the same until they take the mound. Read the rest of this entry »

In the Beforetimes, mid-September brought my annual check-in on the potential for end-of-season chaos in the playoff races via the Team Entropy series. With last year’s introduction of an expanded and restructured postseason, however, Major League Baseball did away with the potential for scheduling mayhem in favor of a larger inventory of playoff games. Along with the expansion of the playoff field from 10 teams to 12 and of the Wild Card round from a pair of winner-take-all games to a quartet of three-game series, MLB also eliminated all winner-take-all regular-season tiebreaker games. In the name of efficiency, we have no more Games 163 and no more potential Bucky Dents. Instead, ties, even for spots where the winner would receive a postseason berth and the loser would go home, are decided by mathematics. It’s enough to make a fan want to shout, “Hey, Manfred, pull your head out of a spreadsheet and watch an elimination game!”

The untangling of the often-chaotic scenarios by which those one-game tiebreakers could come about was Team Entropy’s raison d’etre. But particularly with so many close races, there’s still enough untangling to do in potentially complex tie scenarios that I’ve chosen to continue a version of this exercise, pouring out a cold one for what might have been. If what we’re left with isn’t exactly chaotic, you can thumb your nose at the commissioner as you take a seat on the Team Un-Tropy bandwagon. Read the rest of this entry »

Perhaps it’s too soon to say that Drew Smyly has turned his season around from the bullpen, but he’s certainly on the right track. In 22 starts this year, he pitched to a 5.40 ERA and a 5.32 FIP. Opposing batters slashed .274/.337/.501 against him; in other words, he turned the average hitter into Austin Riley. On the flip side, Smyly has a 3.72 ERA and 3.41 FIP in 19.1 innings of relief. Over the past month, he has looked even better. The small sample size disclaimer applies, but even so, his 2.61 ERA and 2.29 FIP are notable. His opponents are slashing .237/.293/.421; that’s less Riley and more Hunter Renfroe.

As a starter, Smyly wasn’t a big strikeout threat. Yet, as a reliever, he has struck out 27 of the 80 batters he has faced. That’s a 33.8% strikeout rate, or 12.57 K/9. Since his first relief appearance on July 22, he ranks among the top ten qualified NL relievers in both metrics. Even better, he has upped his strikeouts without giving out any more free passes. His 8.0% walk rate was run-of-the-mill for a starting pitcher, but his 7.5% rate is significantly better than average for a bullpen arm.

The pitch-level data helps to explain Smyly’s transformation into a strikeout artist. He’s throwing all three of his pitches with increased velocity and using his best whiff pitch, his curveball, more often. His zone rate is up, as is his chase rate, and as a result, he’s earning more whiffs and first-pitch strikes.

Now that I’ve thoroughly impressed you with tales of Drew Smyly reborn, it’s time to come clean. The veteran southpaw’s performance as a reliever isn’t the real reason I’m writing about him today. As good as he’s been, I need to see more than 11 appearances before I dub him the next Dennis Eckersley. But while I was comparing Smyly’s stats between the bullpen and rotation, one number stood out more than any other — more than the velocity, more than the walks, and even more than the strikeouts.

When the Cubs signed Seiya Suzuki before the 2022 season, it was part of a bold strategy to accelerate their return to contention. They weren’t quite ready for their close up that year, but the general plan was pretty clear: add a few pieces then, tack on more the following season, and aim for a good team sooner rather than later.

Good news! That plan has worked. The Cubs are in playoff position in mid-September, just like they drew it up. They supplemented 2022’s free agency exploits with a double dip last offseason. Cody Bellinger and Dansby Swanson have been right at the forefront of the charge, though Swanson has slumped recently. But for a bit, it looked like Suzuki might not be a part of Chicago’s plans.

He coasted through 2022, a solid righty bat but hardly one of the best hitters in the league. He started off this season in a funk, dealt with injuries, and finally got benched in early August. It was a long fall for someone so heralded, but honestly, you can see what the Cubs were thinking. Through that point in the year, Suzuki was batting .249/.328/.389, good for a 96 wRC+, and striking out a worrisome 25.3% of the time. He’d slumped as the year wore on, to boot; he had a wRC+ of 59 in the months of June and July. Read the rest of this entry »

The Cubs are in playoff contention at the end of August, and Kyle Hendricks is getting hitters out with a tasting menu of exquisitely located mid-80s funk. (Grabs nearest passerby) “The date! I need you to tell me the date!…God Almighty, my time machine works!”

For most of the late 2010s, Hendricks was not quite an ace but was a bankable no. 2 or no. 3 starter. Even in his relative youth, he never threw hard; the fastest pitch of Hendricks’ entire career was 93.1 mph, and he hasn’t even hit 91 since 2016. People who apparently never watched Greg Maddux loved to stamp a “next Greg Maddux” label on any bookish right-hander with great command, and of those, Hendricks probably came the closest to living up to the comparison.
