Demarcus Evans, RHP, Texas Rangers
Level & Affiliate: Triple-A Round Rock Age: 24 Org Rank: TBD  FV: 40+
Line: 2 IP, 0 H, 2 BB, 5 K
Notes
Evans lives almost entirely off his fastball’s carry and angle, which punishes hitters at the top of the zone. I saw him sit 94–96 mph during the spring. He can also dump in an inconsistent 12-to-6 curveball, but his feel for burying it is still poor, and it hangs in the zone too often. In an attempt to find a more impactful second pitch, Evans has added a cutter. The outing I saw during the spring was his second or third time using it, and it was understandably of mixed quality. We’re still talking about a premium fastball here, though — one that plays in a similar fashion to James Karinchak‘s and Nick Anderson’s fastballs. But there’s just no second plus offering to pair with it. I think it’s more likely Evans ends up in a middle relief role early on, but he’s a high-leverage lock if a secondary pitch ever materializes.

Cleveland develops pitchers as well as any team in baseball, and that’s good news for Tanner Burns. The second of the club’s two first round picks last summer, Burns has an Auburn University pedigree and a high ceiling. He also has some question marks, as evidenced by Eric Longenhagen — who acknowledged that he’s “a little lighter on Burns than the industry consensus” — having ranked the 22-year-old right-hander conservatively at No. 20 on the team’s 2021 Top Prospects list. Baseball America is somewhat more bullish on Burns, slotting him at No. 15 on their own list.

The Decatur, Alabama native has pitched solidly in his first two appearances of the season. In a pair of starts for the High-A Lake County Captains, Burns has allowed four hits and two runs, with one walk and 13 strikeouts, his fastball sitting 94-95 and topping out at 96. He discussed his approach to pitching, and the influences of Tim Hudson and Casey Mize, following his initial outing.

———

David Laurila: Let’s start with an icebreaker I’ve used several times in the past: Do you consider pitching to be more of an art, or more of a science?

Tanner Burns: “I feel it’s more of an art. I try to keep it plain and simple, like straight vanilla. With my release points, I think ‘off my right ear’ to go inside on a righty, ‘off my nose’ for down the middle,’ and ‘off my left ear’ for away to a righty.’ So I kind of take it as an art, delivering my pitches, letting it come off my hand.” Read the rest of this entry »

Below is an analysis of the prospects in the farm system of the Seattle Mariners. 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. Each blurb ends with an indication of where the player played in 2020, which in turn likely informed the changes to their report if there were any. 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.

Earlier today, the Seattle Mariners promoted Logan Gilbert and Jarred Kelenic to their active roster; both are expected to start in tonight’s game against Cleveland. The joint moves are the latest and most decisive steps to date in Seattle’s rebuild, and mark the next phase in the Mariners’ quest to construct a contender around a nucleus of homegrown talent.

This is undoubtedly a big day for the Mariners and their fans. As you probably know, the team owns the longest playoff drought in major American sports, a streak now in its 20th year. In those two decades of fits and starts, aborted tear-downs and calamitous collapses, Seattle has teased fans with young and talented rosters before. But while there’s never any guarantee that bluechip farmhands will live up to their billing, this era has a different feel to it. The current regime’s player development staff already has a few wins under their belt, and Seattle’s farm system is deeper than in previous rebuilding cycles, particularly when it comes to premium position players: In Kelenic and Julio Rodríguez, the Mariners have a pair of prospects with legitimate star potential.

There’s not much I can tell you about Kelenic that Eric Longenhagen hasn’t covered already. We have him as the game’s fourth-best prospect right now, a player who projects as a plus bat and one who may have muscled his way into plus power as well. Mariners fans will find much to salivate over in Eric’s full remarks, but as a brief teaser: “Kelenic rakes. His feel for contact, strength, and mature approach combine to make him a lethal offensive threat… I expect him to come up in 2021 and be an immediate impact player.” We’ll talk more about all of the learning and developing and maturing he did in his six games down in Tacoma later. For now, suffice to say that his spring and Triple-A appearances did nothing to damage his stock. Read the rest of this entry »

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 »

First, a bit of history:

The major league annals include just two players born in Slovakia. One of them is Elmer Valo, an outfielder for six teams from 1940-1961 who hailed from the village of Rybnik. The other is Jack Quinn (born Johannes Pajkos), a pitcher for eight teams from 1909-1933 who drew his first breaths 333 kilometers away in Štefurov. Both came to the United States at a young age, their families settling in the Pennsylvania.

Adam Macko hopes to follow in their footsteps, albeit via pathways. A native of Bratislava, Slovakia, Macko moved to Stoney Plain, Alberta, Canada when he was 12 years old — a year in Ireland bridging the Atlantic journey — and then to the southern part of the province where he spent three years at the Vauxhall Baseball Academy before being selected by Seattle in the seventh round of the 2019 draft.

Profile-wise, Macko is more finesse than power, albeit not by a wide margin. The 20-year-old called himself “a command lefty” when offering a self scouting report, but that belies a velocity jump that saw him clocked as high as 97 mph in spring training. In his first start of the season, Macko sat 92-96 with his four-seamer while hurling four scoreless innings for the Low-A Modesto Nuts. Mixing and matching effectively, the southpaw set down seven Stockton Ports batters on strikes. Read the rest of this entry »

Corbin Carroll, CF, Arizona Diamondbacks
Level & Affiliate: Hi-A Hillsboro   Age: 20   Org Rank: 1 (20 overall)   FV: 60
Line: 3-for-5, HR, 3B, BB, 2 SB

Notes
I’m going to bet Carroll goes to the Futures Game and ends up promoted to Double-A shortly after the showcase. He’s shown no signs of slowing down after looking like the best player in all of Arizona during 2020 instructs. This is the kind of player who’s going to out-produce his raw power in games because the quality of his contact is just so good. His homer yesterday (which tied the game in the ninth) was hit to the opposite field. It wasn’t like a lot of oppo bombs that rely on brute strength (think of Giancarlo Stanton’s right-center homers) or just happen to suit the swing path of someone with big power (Ryan Howard). Instead, Carroll just dove to try to cover the outer third of the plate and poked the barrel there, and he hit the bottom of the ball with the sweet spot of the bat. Read the rest of this entry »

Robert Hassell III, CF, San Diego Padres
Level & Affiliate: Low-A Lake Elsinore   Age: 19   Org Rank: 5   FV: 50
Line: 3-for-5, HR, 2B, BB, 2 SB

Notes
Perhaps the most important thing about Hassell’s first pro season will be how he looks in center field. His first step out there is pretty good, but he sometimes struggles to close the deal, especially when he’s approaching the wall. Hassell hit with substantially more power during 2020 instructs, then arrived to 2021 spring training (where he got a lot of run with the big league team) with a really steep, uphill swing, and I watched him swing through a lot of fastballs with lateral action during minor league spring training. Clearly games like last night are an indication that’s okay, I’m just noting there may be a contact-for-power tradeoff happening here based on my spring looks. Read the rest of this entry »

Ethan Lindow is low profile at this point in his career. A fifth-round pick four years ago, the 22-year-old southpaw sits humbly at No. 25 on our Philadelphia Phillies Top Prospects list. His lack of stand-up-and-take-notice stuff is largely responsible for his modest ranking. Atypical in an age of high velocity and nasty benders, Lindow is a command artist who attacks hitters with a ho-hum heater and a top-shelf changeup.

The lack of buzz belies his success at the lower levels of the minors. In 211.1 professional innings, Lindow has chewed up batters to the tune of a 2.73 ERA while allowing just 176 hits and 54 free passes. Moreover, the Locust Grove, Georgia native’s ledger includes 220 strikeouts, a noteworthy number given his finesse identity.

A former Phillies prospect now pitching for the Oakland A’s is a comp that came to mind when I spoke to Lindow shortly before he made his Double-A debut with the Reading Fightin Phils. It turned out that it’s someone he’s considered himself.

“He’s a guy I kind of always looked at,” Lindow said of Cole Irvin. “I’d be like, ‘Man, that’s a guy I’d compare myself to.’ I’ve just always been one of those crafty lefties. None of my numbers are going to light up the boards, so I go off my command and movement, and let my defense work.” Read the rest of this entry »
