Sunday Notes: Rockies Prospect Mitchell Kilkenny Channels Calvin and Hobbes

Mitchell Kilkenny is quietly having a stupendous season. A second-round pick by the Colorado Rockies in 2018 out of Texas A&M, the 24-year-old right-hander boasts a 1.47 ERA over eight starts with the Low-A Fresno Grizzlies and the Spokane Indians. Moreover, he’s fanned 54 batters and issued just five free passes in 43 innings.

His plus command is a much-needed asset. Kilkenny is more finesse than power, his fastball ranging from the upper 80s to the low 90s. At least for now. Kilkenny threw harder as a collegian, but then came Tommy John surgery shortly after he was drafted, and last year’s cancelled minor-league season only muddied the waters. No matter. He fully expects his velocity to tick back up in time, and even if that doesn’t happen, his ability to mix, match and tunnel two- and four-seam fastballs, a slider, a curveball, and a changeup has proven to be plenty effective. As Kilkenny put it, “I might not be bright and flashy, but I’m having success.”

Prior to matriculating at Texas A&M where he double-majored in Renewable Natural Resources and Forestry, he excelled in English class at Houston Christian High School.

“My one fun fact is that I won two awards in creative writing contests,” Kilkenny told me. “One was for a class project where we were to write to a favorite author of ours. I picked Bill Watterson, for Calvin and Hobbes, because that was my favorite comic growing up, I love Calvin and Hobbes. Anyway, it was just a little piece about what the author had given me, which was some of the insights you can get out of a simple comic.” Read the rest of this entry »


What’s Up With Nolan Arenado’s Defense?

Heading into 2021, the question that loomed over Nolan Arenado concerned his bat. Could he remain productive outside of Coors Field? Roughly 40% into the season, the answer seems to be yes. Although his on-base and slugging percentage are down, handy wRC+ tells us that Arenado’s offensive output relative to the environment he’s in has remained consistent. On this front, he has been the star the Cardinals had hoped for.

On the other hand, I’m willing to bet good money that nobody was worried about Arenado’s glove. Altitude doesn’t affect one’s footwork or agility. We expected him to continue his life as one of the league’s best third basemen. And all things considered, he still is one of the league’s best third basemen. What follows isn’t the sound of panic, but rather a fact to keep in mind. Consider Arenado’s defensive numbers this season:

Arenado’s Defensive Numbers, 2016-21
Year Innings DRS UZR OAA
2016 1377.1 13 3.3 14
2017 1343.1 17 6.7 9
2018 1328.1 12 5.8 11
2019 1319.2 24 10.3 21
2020 417.1 11 8.5 7
2021 600.0 3 1.0 0

They’re… okay. Huh. That being average elicits this sort of reaction is a paean to Areando’s talent. When the three big defensive metrics all agree that his defense has taken a step back, though, you have to wonder – what’s going on? He’s no pumpkin at the hot corner, but he’s also not the superstar we’ve become accustomed to. Prorate his 2021 DRS to his 2019 workload in terms of innings fielded, and you’d wind up with 7 DRS after rounding up. That would represent the lowest mark of his career. Defensive metrics are imperfect and noisy, sure, but confronted with these changes, there’s probably some signal worth analyzing.

For this article, I’ll be focusing on Baseball Savant’s Outs Above Average. Our in-house metric is UZR, but it unfortunately doesn’t account for infield shifts, which will become relevant later on. Read the rest of this entry »


Let’s Hear From a Pair of Red Sox Prospects

Triston Casas and Grant Williams are teammates with distinctly different profiles. Boston’s first-round pick in the 2018 draft, the 21-year-old Casas is a 6-foot-4, 250-pound first baseman who is No. 2 on our Red Sox Top Prospects list, and No. 42 on our updated Top 100 Prospects list. Williams is unranked. A 25-year-old middle infielder who lasted until the 310th pick of the 2018 draft, he hit in the nine-hole when the Double-A Portland Sea Dogs hosted the Somerset Patriots on Wednesday night. Befitting his stature, Casas batted third.

Prior to the game, I spoke to both players about their respective hitting approaches.

———

Casas possesses plus power, but he doesn’t present as a pure slugger. Patience is a big part of his M.O., as is a willingness to choke up on the bat when contact is at a premium. The lefty swinger cited Joey Votto as his role model when he was featured in a January 2020 Sunday Notes column, and as he acknowledged on Wednesday, that remains the case.

I asked Casas if he’s changed as a hitter since entering pro ball three years ago.

“I’d like to think I haven’t, but I have a lot,” responded the Plantation, Florida product. “I kind of battle that. I fight every single day to make adjustments and become the best hitter that I can, but to also apply what I’ve been doing my whole life. So I like to say that I haven’t changed too much, but at the same time, I have.”

I asked the up-and-coming youngster if he could elaborate. Read the rest of this entry »


Scouting Three Potential First Round Arms

The 2020 draft was instructive to many teams, as it taught them how to scout off data and video since multiple in-person looks were made impossible by the pandemic. And while scouts are back on the road, data and video remain important tools, with some teams giving them the same weight as in-person reports. With access to many of the tools that teams lean on come draft season, I am able to view data and video from nearly every pitch thrown by Division I college arms. So in that spirit, I decided to write up some potential first rounders.

While a great deal of draft coverage when it comes to pitching has focused on Jack Leiter and Kumar Rocker, the two much-lauded Vanderbilt arms, there are somewhere between five and seven college pitchers who could also end up first-round picks and demand some attention. I start today with three of them — two who began the year highly regarded by the industry, and a third who has jumped up on boards considerably this spring.

Ty Madden, RHP, Texas

Statistics: 107.2 IP, 71 H, 7 HR, 41 BB, 129 K

2021 Year in Review: Madden came out strong but had some hiccups in late April and early May as he struggled with his command. He finished the year on a high note, including a 7-4-2-2-2-10 line against Mississippi State in Omaha.

Physical Description: 6-foot-3, 215 pounds. To use the scouting cliché, this is what they look like.

Delivery: Utilizes power frame well. Big kick, good hip tilt and leg drive with on-line landing. Finishes a bit wild with very high back leg coming around and creating big spin to the first base side. Leans into a high (12:30) arm angle that produces very good fastball shape.

When 92 Is Actually 95: Bailey Falter’s Extension Adds Meaningful Velocity

What if I told you that there is a pitcher who throws 92 mph but is actually throwing 95? That’s just Bailey Falter’s niche. Despite only throwing nine major league innings in his career to date, Falter has already shot to the top of some important leaderboards: release extension and average velocity added.

Here are the top-10 fastballs in June, sorted not by average velocity, but instead by average added velocity, which is the result of simple subtraction: effective velocity minus release speed. Effective velocity estimates the “actual” pitch speed the hitter faces based on where the pitcher releases the baseball and how much time the hitter has to react. If a pitcher releases the ball closer to home plate, the batter has less time to react, effectively (there’s that word again) making the pitch come in faster. This is music to Falter’s ears:

Top-10 Fastballs by Added Velocity, June
Player Pitch Type Release Speed Effective Velocity Difference
Edwin Díaz FF 99.5 103.3 3.8
Garrett Whitlock SI 94.6 98.2 3.6
Bailey Falter FF 94.1 97.5 3.4
Logan Gilbert FF 93.3 96.7 3.4
Tyler Glasnow FF 95.9 99.3 3.4
Bailey Falter SI 93.6 96.9 3.3
Bailey Falter FF 92.6 95.9 3.3
Bailey Falter SI 90.0 93.3 3.3
Bailey Falter SI 92.5 95.7 3.2
Logan Gilbert FF 96.7 99.9 3.2

Daily Prospect Notes: Wander Franco Edition

Because there are so few minor league baseball games on Mondays this year, you’ll see me play with the format of the Tuesday Daily Prospect Notes. I’m lucky that the top prospect in the sport, 20-year-old Tampa Bay Rays infielder Wander Franco, is likely to debut against the Red Sox this evening. The Franco report from the Rays/Top 100 lists still applies, and folks looking for a general overview of his talent should go jam on the clipboard here and read that if you haven’t already done so. Today I’m going to be breaking down his 2021 season using Synergy Baseball, a pitch-by-pitch video software program that is often used by MLB teams.

We made a decision to allocate scouting travel budget toward Synergy Baseball during the offseason, when the timeline for vaccines was still hazy but the presence of COVID was not. Unsure if/how much I’d be travelling again this year, we funneled money into Synergy in case I could not. It was initially useful for watching action in foreign pro leagues and during Spring Training as I worked on prospect lists, but Kevin Goldstein and I also have access to pitch-by-pitch video from Triple-A games (not the whole minors, just Triple-A), as well as metadata from each pitch. I can’t share video with you here (or anywhere) or I’d be in violation of MiLB.tv terms of service, but I can share with you some of the Franco metadata to illustrate the specific nature of his skills and put them in a big league context.

FanGraphs Power Rankings: June 14–20

The biggest storyline in baseball this week was the announced crackdown on pitchers using foreign substances on the mound. It’s still too soon to tell how this might change the results on the field, but the early research suggests it could have wide reaching effects. Scoring is up in June league-wide, but that may be the normal result of warmer weather.

A quick refresher: my approach takes the three most important components of a team — their offense (wRC+) and their starting rotation and bullpen (50%/50% FIP- and RA9-) — and combines them to create an overall team quality metric. I add in a factor for “luck” — adjusting based on a team’s expected win-loss record — to produce a power ranking.

Tier 1 – The Best
Team Record “Luck” wRC+ SP- RP- Team Quality Playoff Odds Δ
Dodgers 44-27 -3 113 80 105 156 ↗ 99.1% 2
Giants 46-26 0 110 86 101 152 ↗ 74.8% 2
White Sox 43-29 -3 107 81 88 175 ↘ 86.6% -2

The Dodgers have finally reclaimed the top spot in these rankings by winning 10 of their last 12. They’re about to get a lot healthier, too; Max Muncy and Cody Bellinger should be activated from the IL this coming week, and Corey Seager could start a rehab assignment as early as next weekend. That’s good, because their upcoming schedule is tough, with series against the Padres, Cubs, and Giants on the docket.

The Giants’ offense was absolutely dominant last week, beneficiaries of playing the Diamondbacks and Phillies at home; they scored 59 runs in seven games with Brandon Belt and Mike Yastrzemski leading the way. Those two combined to collect 18 hits last week, including eleven extra-base hits and five home runs. But one of the biggest reasons for San Francisco’s continued success has been the vast improvement of its bullpen. At the end of April, Giants relievers had the second worst park- and league-adjusted FIP in baseball. Since that point, they’ve lowered their FIP- to 98 and their ERA- to 81.

Sunday Notes: Undrafted, Reds Prospect Braxton Roxby is Borderline Unhittable

Braxton Roxby was an unpolished gem when the Cincinnati Reds signed him as a non-drafted free agent last summer. A 6-foot-3, 235-pound right-hander, Roxby possessed projectable stuff, but his resume was anything but shiny. In three collegiate seasons with the Division-II Pittsburgh-Johnstown Mountain Cats, he logged a 7.31 ERA. Moreover, that number was 9.68 in his junior year.

Then came Kyle Boddy and the Reds pitching-development machine.

In what is shaping up as one of the best underdog stories in recent memory, Roxby has been shoving in his first professional season. Pitching in a relief role for the High-A Dayton Dragons, the 22-year-old hurler has surrendered just four hits and one run in 16 innings. He’s punched out 28 batters.

How he ended up signing with Cincinnati is a story in itself. Roxby talked to 20-plus teams after being bypassed in last year’s truncated draft, and the tenors of the conversations were largely the same… with one notable exception.

“The Reds were the only team to take it a step above,” said Roxby, who majored in Civil Engineering at Pittsburgh Johnstown. “They had me on a Zoom meeting — [Director of Pitching] Kyle Boddy and [Assistant Pitching Coach] Eric Jagers were both on there — and they had video breaking down my mechanics, as well as the analytics of my pitches and how I can use them better. That made it hard not to choose them.” Read the rest of this entry »


Top 33 Prospects: Oakland Athletics

Below is an analysis of the prospects in the farm system of the Oakland Athletics. Scouting reports were compiled with information provided by industry sources as well as my own observations. As there was no minor league season in 2020, there are some instances where no new information was gleaned about a player. Players whose write-ups have not been meaningfully altered begin by telling you so. As always, I’ve leaned more heavily on sources from outside of a given org than those within for reasons of objectivity. Because outside scouts were not allowed at the alternate sites, I’ve primarily focused on data from there, and the context of that data, in my opinion, reduces how meaningful it is. Lastly, in an effort to more clearly indicate relievers’ anticipated roles, you’ll see two reliever designations, both on my lists and on The Board: MIRP, or multi-inning relief pitcher, and SIRP, or single-inning relief pitcher.

For more information on the 20-80 scouting scale by which all of our prospect content is governed, you can click here. For further explanation of Future Value’s merits and drawbacks, read Future Value.

All of the numbered prospects here also appear on The Board, a resource the site offers featuring sortable scouting information for every organization. It can be found here.

The Best Bunts of the Season (So Far)

Earlier this week, I took a look at the worst bunts of the season. They were all horrible! Balls were hit directly at fielders, lead runners were thrown out, and altogether the worst five bunts produced eight outs and no base advancements. Not great! But that’s only one side of the coin, and today I’d like to look at the bunts that have helped the batting team most so far this year.

You’ll notice that there aren’t any textbook sacrifice bunts on either list. That’s no knock on skilled bunters, but rather a function of the way I’m defining best and worst. Bunts, by their very nature, are hedges. They reduce volatility by definition — exchanging an out for some base advances is neither the worst nor best outcome of a given plate appearance, so a successful sacrifice bunt will inherently have a modest change in win probability relative to a play where something goes very right or very wrong.

Even so, today isn’t solely a showcase of bad defense. There’s some bad defense, but there’s also plenty of bunting for a hit. When you change the math by giving yourself a chance to reach base, bunts become far more valuable. It’s hard to greatly increase your team’s chances of winning while also making an out, so separating the sacrifice from the bunt is a prerequisite for having one of the most valuable bunts of the year.

For the most part, the plays on this list are all baseball being played at a high level. There are some defensive howlers, sure, but there’s plenty of skill here on both sides of the ball. Let’s take a look at the bunts that have helped out the most this year (through June 9), starting with an honorable mention.
