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 »

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 »

Kevin Goldstein and I have updated the pro portion of the Top 100, which means we quickly reviewed the placement of players in the 50 FV tier and above, and considered who was not yet in those tiers but should be based on how they’ve looked during the first month of the 2021 season. I still have three total org audits to do — Milwaukee, Oakland and the Cubs — before I start peeling graduates off the list. Those will be completed shortly. You can find the updated list here.

Also, if you missed it, Kevin and I updated our draft rankings and posted a Mock Draft on Monday.

The lone change up near the top of the 100 is Riley Greene moving into the top 20; he’s in the mix with several other similarly-aged players with the talent to be consistent All-Stars, like Bobby Witt Jr., Julio Rodríguez, and Corbin Carroll.

DL Hall moved into the 55 FV tier on the strength of his stuff. He’s still walking a fairly high rate of opposing batters but just on the strength of his three plus pitches, could be a Haderesque relief weapon even if he can’t start. Read the rest of this entry »

Jharel Cotton is trying to revive his career in the Texas Rangers organization. Three years removed from Tommy John surgery — and four years after making 24 starts for the Oakland A’s — the 29-year-old native of the Virgin Islands is taking the mound for the Triple-A Round Rock Express. Progress has been slower than ideal. In eight appearances comprising 17-and-two-thirds innings, Cotton has a 4.58 ERA and, more importantly, less feel for his deliveries that he did pre-injury.

He believes it’s only a matter of time.

“I didn’t play in 2018, I barely played in 2019, and 2020 was a scratch because of the pandemic,” Cotton explained earlier this week. “Now 1 have a full year, and within a full year I’ll be back to myself. I just have to keep putting in the work and trusting the process — going through the process of getting my arm to feel normal again. A lot of guys get back quickly and other guys get back not as quick. Everything will work out in its own time.”

Cotton’s velocity is slowly coming back — his fastball has been ranging between 92-96 mph — although his command has lagged a little behind. Ditto the crispness of his cutter, curveball, and changeup. But again, he’s not overly concerned. As he put it, “I lost a lot of those things, but I feel I’m putting the pieces back together.”

Cotton’s comeback isn’t the only reason I wanted to talk to him for today’s column. I also wanted to revisit a story I’d read about him back when he was still pitching for the A’s.

Originally in the Los Angeles Dodgers system, Cotton went to Oakland in August 2016 as part of a five-player deal involving Rich Hill. A few years earlier, he was a minor-leaguer making ends meet during the offseason. That’s when he learned to love shoveling snow. Read the rest of this entry »

The Red Sox caught us all by surprise by jumping out to an incredible start en route to an early-season lead atop the AL East. As Tony Wolfe wrote, the strong performance was largely thanks to consistent run-scoring and a dominant bullpen. Fast-forward to mid-May, and Boston is still there, first in the division and continuing to climb up various weekly Power Rankings (including our own). As impressive as the Red Sox have been at the plate, though, the rotation seems to have been overshadowed. I get it; there’s not a lot of name brand recognition. Their two best starters from 2019, Chris Sale and Eduardo Rodriguez, pitched a grand total of 0 innings in 2020. But after taking three of four from the Angels over the weekend, the Red Sox lead the American League in FIP (3.29) among starting pitchers.

Leading the charge is Nathan Eovaldi. His most recent start extended his streak without giving up a homer to 50 innings; he is the only qualified starting pitcher who has yet to do so. That helps make up for a modest 4.50 ERA and strikeout-per-nine rate of 8.46; his FIP is 2.15. Since he’s been in Boston, Eovaldi has struggled with home runs, allowing an average of 1.86 per nine over the past two seasons. That makes sense, as he’s always allowed a lot of balls to be put in play with a penchant for giving up the occasional dinger. But so far this season, the expected value in terms of xwOBA on those balls suggests that Eovaldi is eliciting softer contact, which is supported by his peripherals.

Eric’s Notes (Games from May 12)

Cody Poteet, RHP, Miami Marlins
Level & Affiliate: MLB   Age: 26   Org Rank: 24   FV: 40 Line: 5 IP, 4 H, 2 R, 0 BB, 6 K

Notes
Poteet was a prospect several years ago, last on the Marlins list in 2017 (it was just 13 names long) as a potential backend starter. He had a two-tick velo bump during quarantine, and after sitting 89-93 and topping out at 95 in 2019, he’s sitting 92-95 and touching 96 now. He had a 10-strikeout start in his first 2021 minor league outing then was immediately promoted to the big league team for Wednesday’s start. It’s surprising that Poteet had such a late bump in velocity. His era of UCLA pitcher had already adopted Driveline principals, and I would have guessed he was already maxed out. Of his three secondaries, Poteet most-often deploys his changeup, a heavy, sinking offering in the 85-88 mph range. His slider has more linear movement than two-planed sweeping shape, but it can still miss bats if it’s located away from righty batters. His curveball has plus-plus spin rates but is easy to identify out of his hand since he has a sink/tail-oriented fastball, and Poteet hung a couple of them Wednesday, one of which got put into the seats. The limited utility of his breaking balls and his fastball being more of a grounder-getter than a bat-misser holds Poteet in the low-variance backend starter bucket for me.

These are notes on prospects from lead prospect analyst Eric Longenhagen. Read previous installments here.

Jarren Duran, CF, Boston Red Sox
Level & Affiliate: Triple-A Worcester   Age: 24   Org Rank: 7   FV: 45
Line: 2-for-5, 2 HR, 2 K

Notes
This is the kind of thing you like to see from a guy who clearly underwent a swing change last year but wasn’t able to play in actual games to show us if it was going to have a meaningful impact. In fact, when Duran went to Puerto Rico for winter ball after spending the summer at the alt site, he failed to hit for power there as well. Now he already has three homers in 2021, which is just two shy of his single-season career high. As he’s doing this, Duran is also striking out 33% of the time, a far cry from the ultra-low rates that helped make him a prospect in the first place. It’s rare for a prospect this old to be such a high-variance player. We’re all learning about how Duran’s swing change is going to alter his output in real time. Read the rest of this entry »

In 2018, Matt Barnes had a promising season for the Red Sox. He struck out 36.2% of the batters he faced en route to a 3.65 ERA and 2.71 FIP. His one weakness? He walked 11.7% of the batters he faced, a dangerous number. That pattern carried through to 2019; he struck out 38.6% of his opponents but walked 13.3% of them. That strikeout rate is wonderful, but the walks gave him little margin for error, as evidenced by 2020, when he struck out 30.4% of his opponents (still great) but walked 13.7% on his way to a below-replacement-level season.

In 2021, you’ll never believe it — Barnes is striking out the world again, with a 48.4% strikeout rate that’s fourth among relievers, behind only Aroldis Chapman, James Karinchak, and Josh Hader. Oh yeah — he’s also walking 4.8% of his opponents and has been quite possibly the most valuable reliever in the game. Let’s get an explanation for that, shall we?

At surface level, it’s easy! Take a look at swinging strike rate, a statistic that becomes reliable quickly:

A 19.1% swinging strike rate is excellent; top-of-the-league excellent, really. Also true: Barnes hasn’t changed his pitch mix. He’s a two-pitch reliever, with a riding four-seamer and hammer curve. He throws them both roughly half the time, and they spin more or less exactly opposite out of his hand, which seems to help them both play up:

Great, problem solved. Hard curveball, decent fastball, they both play into each other’s deception, sounds like a good reliever to me. One small problem: there are maybe 50 relievers like that in baseball, and Barnes was also like that in the past, when he was far more walk-prone without his current killer strikeout numbers.

So far, the Red Sox have been one of this season’s biggest surprises. Since Opening Day, the Sox have already increased their playoff odds by 23.6 percentage points up to 61.5%, the second-largest percentage point increase in baseball (Athletics, +25.7).

To reach the pinnacle of the AL East this quickly, Boston has been successful on both sides of the ball, but it’s the team’s offense that has found itself alone at the top of most major league leaderboards. Through games on Saturday, the Red Sox are slashing .269/.334/.445, with the batting average and slugging percentage each ranking tops among the 30 teams. Their .338 wOBA is seven points above the next-best team, the Dodgers, and their park-adjusted 115 wRC+ is three points above Los Angeles as well.

The entire lineup is hitting, but it’s their core five of J.D. Martinez (195 wRC+), Xander Bogaerts (176 wRC+), Rafael Devers (150 wRC+), Alex Verdugo (135 wRC+), and Christian Vázquez (100 wRC+) that have more or less led the way. And though this could easily be an article about any of those five players’ starts, I want to highlight Devers, whose .281/.371/.544 slash line through games on Saturday actually represents one of the biggest under-performances in baseball relative to his batted ball quality.

Eduardo Rodriguez has been one of the vital cogs for the resurgent Red Sox. Sure, Boston’s league-leading wRC+ is the main impetus for the club’s success. But both the starting rotation and the bullpen have been in the top third of the league and Rodriguez has been one of the larger actors of the former’s placement among the league-leaders. Rodriguez has accumulated 0.4 WAR in just four starts and 23 innings of work. He sports a 3.52 ERA and 3.34 FIP despite allowing a gaudy 17.4% HR/FB. The main driver of his results? Not only is he striking out a shade more than 29% of opposing hitters (after posting marks of 24.8% and 26.4% the previous two seasons), his walk rate sits at a sparkling 2.2%. This start is already extremely impressive. But in the context of what he endured in the very recent past, I would say it’s extraordinary.

For those unfamiliar, Rodriguez missed the entire 2020 campaign. It wasn’t due to an elbow injury or shoulder soreness or forearm tightness. Rodriguez suffered myocarditis; a heart condition connected to contracting COVID-19. Speaking to Joon Lee of ESPN, Rodriguez said he could not throw pitches without feeling significant fatigue brought on by the effects of his condition. He was unable to train for three months. This meant that not only did he miss last season but he was behind the proverbial eight ball when it came to preparing for the 2021 season.

Getting back on the mound was an amazing accomplishment alone. Having one of the most dominant starts to the season among all starting pitchers is one of the most surprising developments of the young season. Rodriguez has not just picked up where he left off. He has adjusted his pitch mix and fundamentally changed the method by which he attacks hitters.

His fastball velocity is down a half a tick, despite the league average increasing by half a tick.

But that hasn’t proven to be a problem. As I alluded to, he has made major tweaks to his arsenal in 2021. In his first three major league seasons, Rodriguez leveraged his plus fastball velocity by throwing the pitch about 60% of the time. As the velocity diminished, he began to rely on the pitch less in 2018-19. Now the four-seamer is his second-most used pitch:
