Eric A Longenhagen: Okay, let’s begin…

12:03
Bernie: I’m intrigued by three Cardinals prospects who seem to get little publicity: Andrew Knizer, Adolis Garcia and to a lesser extent Harrison Bader. What are your thoughts on them?

12:04
Eric A Longenhagen: I think they all have a chance to be everyday players. Knizner as a bat-first catcher, Garcia needs to be more patient to get there, Bader is sneaky fast and viable in CF.

A Glance at Matthew Liberatore’s Draft Stock

Because his high school is only about 40 minutes away via the 101 Loop in Arizona, I am going to see an awful lot of LHP Matthew Liberatore this spring. At the second of two fairly disparate starts from the senior, several teams picking in the top ten had a little extra heat in attendance to observe him. Indeed, after Liberatore sat 93-97 in his first start, there’s been some admittedly premature discussion about how high he might go in the draft. But now that we have a few appearances worth of information this spring, it’s reasonable to begin considering where he might go in June. We can do that by ignoring the other prospects in this year’s draft class and instead comparing Libby to other recent prep lefties.

This style of temperature check is useful for a few reasons. At some point, we have to line up every prospect in this year’s draft class, but it’s hard to do that with precision right now because evaluations are constantly shifting and we don’t know everything about things like signability or injuries. By comparing a current prospect — in this case, Liberatore — to his peers in previous draft classes, we’re now only dealing with one moving target and can more easily get an idea of where he’s likely to be selected.

There are several factors besides mere talent that influence where a player is selected in the draft — especially early in a draft — and, of course, the quality of talent in a given class is also relevant. We can’t control for that stuff and probably don’t need to because, again, we’re just trying to get a feel for a realistic range of potential outcomes.

With that in mind, here are the draft-day evaluations of the high-school lefties who have been taken in the first round since 2014. I have them listed in order of preference based on talent at the time they were drafted, with other factors (size, makeup, delivery) noted. The “x” indicates that attribute was essentially value neutral, or at least not so impactful that it affected the player’s stock. These were all future, not current, pitch projections, and if a kid had two breaking balls I just picked the better of the two.

So where does Matthew Liberatore stack among this group? Last week, he was up to 94, sitting mostly 91-92 for most of his start, with a fairly upright delivery that I think negatively impacts extension. His slowest fastball was at 88; it came from the stretch late in his start. Liberatore’s curveball flashed plus several times. It’s fair to question if a 70-72 mph curveball will be effective in the big leagues, but there’s remarkable feel for spin here and it’s likely Liberatore’s breaking ball will have more power to it at maturity. He flashed an above-average changeup, which projects to plus at peak as he utilizes it more in pro ball.

From a strike-throwing and consistency perspective, Liberatore was disappointing. He failed to get on top of many fastballs and breaking balls, forcing a number of pitches to sail up and to his arm side. The quality of his stuff was also inconsistent throughout much of his outing. He’s a good athlete for his size and has some room on his frame for more mass, so it’s possible more velocity is coming. As the spring rolls on, this evaluation is likely to change a little but, but right now here’s where we think Liberatore is at.

^Allard missed time with a stress reaction in his back as a senior

Groome and Allard probably go higher in their respective drafts if not for off-field and injury issues, respectively. I think it’s fair to place Liberatore in the picks No. 3 to 7 range right now, just based on how his talent stacks up with recent precedent. A lot can still happen between now and the draft to change this. If his velocity ticks comfortably into the mid-90s as the draft approaches, we’re talking about something closer to Gore than to Garrett. We can use similar methodology (especially during the summer prior to a draft) across a draft class to loosely tier players, while being mindful of changing industry norms. As the draft approaches, though, it’s necessary to polish up the order within a given tier or move players around because of makeup, medicals, and other considerations.


Scouting Corey Kluber as an Exercise

In my weekly chats or in the comments section of certain posts, readers often ask a question like, “Does Pitcher X have ace potential?” or some variant of it. While it makes sense that people would be curious about such a thing, the answer is (by definition) almost always “No.” Because there are so few aces in the majors, the probability that any prospect would develop into one is necessarily low.

When I’m at games — and especially when I’m at spring-training games — I’ll occasionally run into someone like Corey Kluber, though. And while I realize nobody’s wondering if Kluber has a chance of succeeding in the majors, there’s some value in writing up guys like this as an exercise, to illustrate what an ace looks like on paper. So that’s what I’ve done here. (Note, as well: context is important when reading the following, as it’s the product of an abbreviated spring look.)

Kluber was 90-92 in my viewing, with enough movement on his fastball to merit a half-grade bump. That’s about 1.5 ticks slower than his average fastball velocity from last year, but this is typical of early-spring Kluber. I put a 55 on his fastball while observing im and imagine it’s plus during the season when he’s throwing harder.

He mixed in a cutter, slider, changeup, and a curveball. The cutter was 86-88 with tight, late movement. It was consistently plus, flashing plus-plus, and Kluber put it where he wanted to when he wanted to. It’s likely that the slider and curveball are the same pitch and that Kluber can just manipulate the shape and depth of the pitch, but the ball acts differently enough when Kluber does this that he functionally has both, even if the catcher puts down the same sign for both. When his breaking ball behaved more like a curveball, it was a 50, a deep, but blunt, 80-82 mph curveball. The slider was one of the best I’ve ever seen, and Kluber threw a few 80-grade sliders in the outing, while most were 70s in the 83-85 mph range. These had more horizontal movement and, like everything else Kluber does, located with precision. I saw a few changeups that I thought were average.

Puk had back issues in college and scouts weren’t enamored with his conditioning, but he also featured premium velocity and a plus slider while performing against SEC hitters. He somewhat surprisingly fell to Oakland’s sixth overall selection in the 2016 draft. Reports were even stronger in 2017.

Could a 5-foot-8 Second Baseman Be Drafted First Overall?

Both Kiley and I will be posting in-person scouting reports on draft prospects we see throughout the spring. Well, summer and fall, too. Here is another dump of notes from Arizona.

Typically, these draft-related posts are designed to provide updates on multiple amateur prospects all at once — and I’ve included shorter notes on some other players below. Today, though, I’d like to dwell a bit on a specific collegiate athlete — namely, Oregon State 2B Nick Madrigal.

Madrigal is the best player I’ve seen so far this spring. He was electric for a weekend and a half during the Beavers’ first two series in Surprise but fractured his wrist on a play at the plate during a win against Ohio State. He was 14-for-25 with two doubles, two homers, three steals in three attempts, and no strikeouts when he went down.

Calhoun doesn’t have a position (he’s been tried at third, second, and in the outfield since college), but he’s going to rake. Scouts have him projected for plus hit and power. He takes huge, beer-league-softball hacks but has the hand-eye coordination and bat control to make it work. He could yank out 30 or more homers as soon as he’s given regular at-bats. The corner-outfield and DH situation in Texas is pretty crowded, but he should start seeing regular big-league time this year. There’s some risk that Calhoun’s aggression is exploited the way Rougie Odor’s has been, but otherwise Calhoun looks like a stable mid-order slugger.

THE Average Sports Fan: Do you think Senzel can be ever decent at SS?

12:04
Eric A Longenhagen: It’s possible. If you assume you can hide what used to be considered subpar range with better positioning then it certainly improves his chances. If I’m skeptical of anything it’s how he’ll look around the bag.

70/70 55/60 60/60 55/60 50/55 45/55

When Whitley remade his physique during his senior year of high school, his stuff and command both ticked up, and they’ve continued to do so. He now sits 93-97. Whitley’s size and delivery create good angle up and down in the zone, and he can sink or cut his fastball if he wants to. He has a knee-buckling curveball, a hard slider, and a burgeoning changeup that has quickly developed into a plus pitch. Whitley’s delivery is a bit violent, but he throws strikes and already has impressive control for a pitcher this size, age, and with this kind of stuff. This unique combination of stuff, pitchability, and command allowed Whitley to traverse three levels last year, ending with four impressive appearances at Double-A. Whitley struck out 143 hitters in 92.1 innings. He doesn’t turn 21 until mid-September and has ace ceiling.
