Oregon righty Matt Mercer threw six innings of two-run ball on Friday night against Arizona State. He struck out eight Sun Devils, walked four, and left scouts with lukewarm feelings about his stuff. Mercer was up to 96, sitting 91-94 throughout his outing, and ASU hitters squared it up pretty often. His best secondary offering was his above-average changeup, which has bat-missing fade and benefits from Mercer’s funky delivery. Neither of Mercer’s breaking balls nor his command impressed scouts. His below-average mid-80s slider lacked movement and mid-70s curveball was fringey. I thought his curveball flashed average and could mature there if it’s used more frequently.

On one hand, Mercer is a college arm up to 96 with an out-pitch changeup and potential average third offering, if you’re willing to project on one of his breaking balls. On the other, he has below-average command right now, not everyone likes his delivery and/or athleticism, and he’s already had one Tommy John. There are some foreseeable avenues that lead Mercer to league-average starterdom but more that run to the bullpen. In the bullpen, maybe his fastball ticks up and singular focus on his changeup means he’s a 60 fastball, 60 changeup reliever with some funk, a la Tyler Clippard.

Brinson has loud physical tools: plus raw power, plus speed, plus arm strength, and the ability to play center field despite mediocre instincts. He didn’t hit for as much power as was expected at hitter-friendly Colorado Springs in 2017, but scouting reports on the raw power, and Brinson’s ability to get to it in games, remain strong. Provided he’s able to make continuous adjustments — and he’s exhibited the ability to do that on his ascent through the minors — Brinson has 25-homer potential. He has had several soft-tissue, lower-body injuries during his career, including multiple hamstring issues, one of which ended his 2017 season. He’s still a plus runner underway but doesn’t reach top speed as quickly as he once did.

This is what it looks like when things start to click on the baseball field for a premium athlete: a .272/.350/.481 line split between two levels, 51 extra-base hits (including 21 homers), and 27 bases stolen at a 87% success rate. Harrison has always had late-bloomer traits. He was a multi-sport stud — not multi-sport athlete, multi-sport stud — in high school and only committed to baseball full time after turning pro. In parts of three pro seasons entering 2017, Harrison missed time with a hamate fracture and broken leg, which prevented him from getting the reps he needed and diluted the way his tools looked on the field when he was.

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.

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.

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.

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.
