The combination of power and command has been striking. In 34 innings split between high-A Dunedin and Double-A New Hampshire, Nate Pearson has punched out 52 batters and issued just six walks. His ERA sits comfortably at 1.32. Blessed with a blistering fastball and a carve-‘em-up slider, he’s the top pitching prospect in the Toronto Blue Jays organization.

The 22-year-old right-hander doesn’t possess a long professional resume. Selected 28th overall in the 2017 draft out of Central Florida Community College, Pearson got his feet wet with 20 innings of rookie ball, then began last year on the injured list with an intercostal strain. Upon returning in early May, he was promptly nailed by a come-backer and missed the remainder of the regular season with a fractured ulna.

Pearson recovered in time to make six appearances in the Fall League, an assignment Jeff Ware, Toronto’s minor-league pitching coordinator, called “a big test given that he’d really only pitched in short-season ball.” In terms of reestablishing his high-ceiling credentials, he passed with flying colors.

Standing a sturdy six-foot-six, Pearson looks the part of a power pitcher, and that’s exactly what he is. Asked for a self-scouting report, he led with that exact definition. Read the rest of this entry »

Mario Impemba is part of the broadcast team in Boston now. The former TV voice of the Detroit Tigers is scheduled to work 51 regular-season games with Joe Castiglione in the Red Sox radio booth this year. The new job is different in more ways than one.

The last time Impemba did radio on a full-time basis was in 2001 when he called games for the Anaheim Angels. He did do a handful of radio games during the 2016 season — Detroit’s broadcast teams flip-flopped a few times that year — but television has long been his comfort zone. No big deal. While the mediums are different animals, the 56-year-old Detroit-area native is making a smooth segue.

“It’s kind of like riding a bike,” Impemba told me in late April. “It was seven years in Anaheim, and prior to that I did eight years in the minor leagues, so I cut my broadcasting teeth in radio. Transitioning back isn’t a big challenge. At the same time, I’m shifting abruptly after doing one medium for [17] years. It took a few games of telling myself, OK, you can’t just say ‘groundball to short; one out.’ On radio you have to describe the mechanics of the play.”

Much like the athletes making the plays being described, broadcasters have honed their skills through years and years of repetition. Be it a grounder to third or a fly to right, there is no shortage of familiarity with what’s happening between the white lines. Read the rest of this entry »

Pitchers learn and develop different pitches, and they do so at varying stages of their lives. It might be a curveball in high school, a cutter in college, or a changeup in A-ball. Sometimes the addition or refinement is a natural progression — graduating from Pitching 101 to advanced course work — and often it’s a matter of necessity. In order to get hitters out as the quality of competition improves, a pitcher needs to optimize his repertoire.

In this installment of the series, we’ll hear from three pitchers —Ryan Pressly, Trent Thornton, and Justin Verlander — on how they learned and developed their curveballs.

Ryan Pressly, Houston Astros

“I started throwing a curveball when I was around 14-15 years old. Steve Busby was my pitching coach growing up — the guy played in the big leagues for a long time and threw a couple of no-hitters — and he taught me his curveball. He told me I could only throw it with him during our pitching lessons. Once I got to eighth grade, or freshman year, is when I started throwing it in games.

“How my curveball works is kind of just a natural thing. My spin rate… I mean, I know why my spin rate increased. You hear all of this stuff about the Astros, but it’s not nearly the case. My spin rate increased because my velocity started increasing. I tore my lat in 2015, and when I came back my velocity kept going up. As the velocity goes up on your curveball, the spin rate is going to go up as well. I’ve also been throwing it more and more, and getting consistent with it. That’s a big reason it has gotten better.

It remains one of the game’s unsolved mysteries. A batter hits a pop-up near the mound and the person closest to it — a professional athlete wearing a glove — isn’t expected to catch the ball. Moreover, he’s not supposed to catch the ball. That job belongs to any one of several teammates, all of whom has traversed a greater distance. As often as not they’re climbing a slope to get under the descending baseball.

Chaos can ensue as the infielders and the catcher converge. The multiple “I’ve got its,” are drowned out by crowd noise and suddenly what should be a routine out becomes an adventure. We’ve all seen it. A bumper-car-like collision occurs and the catch is made clumsily… or not at all.

Just last week, Red Sox right-hander Rick Porcello was charged with an error when he failed to catch a pop up in front of the mound. Not because of ineptitude, but rather because he was veritably mugged by his catcher as the ball was about to arrive comfortably in his glove.

Why aren’t pitchers expected to handle simple pop-ups? They’re perfectly capable, so it makes sense that they should be catching them. Right?

“I don’t know why, and yes, they should be,’ said Seattle’s Perry Hill, whom many consider the game’s best infield instructor. “They’re on on the field of play when the ball is in play, so they should be able to make a play. It’s practiced in spring training. That little short pop-up that nobody can get to. The third baseman is playing way back. The first baseman is way back. The pitcher is the closest guy to the ball. He’ll catch that ball.”

Scott Servais sees it somewhat differently than his first base coach. Read the rest of this entry »

Marcus Walden is a 30-year-old rookie with a 5-0 record, a 1.46 ERA, and a spiked-grip slider that helped rescue him from minor-league purgatory. The story behind the pitch is one of avoidance-turned-desperation, with a healthy dose of studiousness thrown in for good measure. Walden has thrown his slider 41.6% of the time this year in 24.2 innings out of the Boston bullpen.

The righty’s journey to the big leagues was a meandering one. Drafted by the Blue Jays in 2007, Walden subsequently saw time in the A’s, Reds, and Twins organizations. He also spent a summer toiling in the independent Atlantic League. The Red Sox signed him off the scrap heap prior to the 2017 season, but even then his prospect status was tenuous at best. Twenty-six pitchers saw action for the AL East club that year, yet Walden remained in Triple-A.

Walden finally made his MLB debut last April, but his time at the top was short-lived. Sent down in May, he stayed on the Pawtucket roster throughout the remainder of the campaign. This year has been a different story. Walden has been one of Boston’s best relievers — his aforementioned numbers are augmented by a 10.95 K/9 and a 2.46 FIP — and again, his slider is a big reason why. I talked to Walden about his signature offering prior to a recent game.

David Laurila: Your go-to pitch is a slider. What is the story behind it?

Marcus Walden: “I didn’t start pitching until my senior year of high school. My freshman year [at Fresno City College] — the one year I went to school — I was throwing a four-seam fastball and a slider. Now I’ve gone back to that same style of a slider, although with a little bit different grip that I learned from Chandler Shepherd, in 2017. And watching Craig Kimbrel was a big help. I watched him closely, especially in spring training of ’17 and ’18 when he was throwing his live BPs. I talked to him a little. It was, ‘All right. What kind of shape are we trying to make with this pitch?’ He throws a knuckle slider, and that’s what I throw now.”

Hitters deploy their craft in different ways. Not all have the same mechanics, nor do they employ the same approaches. Another thing that differs is the way they articulate their ideas. Proof in that pudding can be found in six similar-themed interviews that have run here at FanGraphs over the past two months. Daniel Murphy, Nolan Arenado, Drew Ferguson, Michael Lorenzen, Jesse Winker, and Matt Chapman have all expounded on the art (or is it a science?) of hitting, and each of their perspectives has been unique.

Mitch Haniger’s is unique, as well. The Mariners outfielder once told me that his hitting approach is complex, which made circling back to gain further insight on what makes him tick a veritable no-brainer. I caught up with the 28-year-old Cal Poly product when Seattle visited Fenway Park this past weekend.

David Laurila: When we spoke in 2013 — you were playing in the Arizona Fall League at the time — you called your hitting approach “pretty complex.” How would you describe it now?

Mitch Haniger: “It’s simple to me. It’s not simple to explain. There are so many factors that go into your approach, based on who you’re facing and what the situation is. How many outs are there? Where in the game are you? Are you facing a starter or a reliever? Not every at-bat is the same. That said, my main focus is essentially to get a good pitch, and hit the ball as hard as possible while taking a nice easy swing.”

Laurila: Getting a good pitch to hit is Hitting 101. How do you balance the simplicity of that approach with the multiple factors you referred to?

Haniger: “I look at pitchers’ tendencies and see how they try to pitch guys. For instance, most pitchers drastically change with runners in scoring position. I’ll look at previous at-bats against a guy and see what he’s typically doing. But really, the overwhelming majority of the time I’m looking for a fastball and trying to stay in the center of the field.”

In order to get hitters out as the quality of competition improves, a pitcher needs to optimize his repertoire.

In this installment of the series, we’ll hear from three pitchers — Jalen Beeks, Dallas Braden, and John Means— on how they learned and developed their changeups.

Jalen Beeks, Tampa Bay Rays

“I had a changeup in high school, but it wasn’t very good. When I got to college, I changed the grip; I moved my pinky finger down. It’s pretty much a circle change. I grip it hard and think about it almost like a fastball. I don’t pronate. No one taught it to me. I just threw it one day and it worked. You have to tinker. You have to figure out what works for you.

“It’s gotten better over the last year. I think that’s mainly from my mechanics having changed a little bit. I use my legs more, and have shortened my arm action. I’m not so tall on the mound now. I’m activating my legs more, by getting into more of a squat position. And like I said, I think fastball. I throw it as hard as I can. My average fastball is around 92 [mph] and my changeup is around 88. Read the rest of this entry »

Rowdy Tellez’s weapon of choice is 34 inches long, weighs 32 ounces, and is made out of maple. Trey Mancini’s is 33-and-a-half inches long, weighs 31 ounces, and is made out of birch. Both do damage. The Blue Jays first baseman is known for his light-tower power, while the Orioles outfielder is coming off of consecutive 24-home-runs seasons.

How they went about choosing, and then settling on, their bat models differs.

“When I first got into pro ball, I signed a bat contract with Victus,” explained Tellez, who was drafted by Toronto out of an Elk Grove, California in 2013. “I told them what I wanted, and they sent me bats. I didn’t really like it at first, so I tweaked it a little more. I got to what they called an AC24, which is kind of a combination of models. It’s kind of like a 271 knob and handle, maybe a little bit thicker heading towards the barrel, and then almost like an I13 barrel, but circumference-wise a little bit thinner, and a tick longer. I’ve kind of stuck with that. It’s a comfort thing.”

Mancini was drafted by Baltimore out of Notre Dame in 2013. Three years later, a C243 model Louisville Slugger became his bat of choice. Read the rest of this entry »

Tanner Houck is off to a book-ended beginning to his second full professional season. Boston’s first-round pick in the 2017 draft allowed seven runs in his first start, and in his fifth, he allowed five. In between, he authored three beauties. Pitching for the Portland Sea Dogs, the 22-year-old righty held Double-A opponents to 10 hits, and a lone marker, over 16 innings.

Houck relies heavily on a worm-killing two-seamer. It’s the pitch that wowed scouts when he was at the University of Missouri, and while it’s once again his go-to, that wasn’t the case over the first half of last season. The Red Sox had Houck put his signature pitch in his back pocket and primarily throw four-seamers against Carolina League competition. The reasoning was sound, but the results weren’t particularly pretty. A fish out of water without his sinker, Houck got hit around.

Come midseason, the Boston brain trust decided that Houck should go back to his old bread and butter. The news came as a relief. His best pitch back at the forefront of his arsenal, Houck proceeded to reestablish himself as one of the organization’s top prospects.

Houck, who takes the hill today in an 11 a.m. matinee, sat down for an in-depth discussion of his two-seamer, and what he gained from last year’s four-seam experiment, at the outset of the current campaign.

David Laurila: How would you describe the transition away from, and back to, your two-seamer?

Tanner Houck: “Honestly, [transitioning back] was just like riding a bike. It was getting back to my staple — back to who I am — and to how my career is going to be going forward. It was enjoyable. At the same time, not having thrown a four-seam in college, learning that side of the coin was really big for me. I’m still throwing one now, and it makes the two-seam that much better. Being able to ride a four-seam through the zone — not sink it — in certain counts has definitely helped. I’m able to give the hitter two different looks with relatively the same pitch.”

Matt Chapman is starting to come into his own as a hitter. Known primarily for his defense — he won a Gold Glove last year in his first full big-league season — the 26-year-old third baseman is slashing .295/.384/.597. He leads the Oakland A’s in all three of those categories, while his nine home runs rank second, behind Khris “Mr. .247” Davis. Moreover, he’s displaying far better discipline than he did a year ago. Along with upping his walk rate, Chapman has nearly halved his K rate. Slowly but surely, he’s becoming an offensive force.

Chapman talked about his offensive approach, which includes looking for pitches middle, middle-away, when the A’s visited Fenway Park last week.

David Laurila: I start a lot of interviews with this question: Do you consider hitting to be more of an art, or more of a science?

Matt Chapman: “Baseball, in general, is kind of like a fine line. So it’s a little bit of both. It’s an art in the sense that everybody is unique — everybody has the things that work for them — and you have to let your natural ability take over. But then there are the mechanics and the numbers. That’s the science part of it. Both are important. You can’t live and die with either.

“For me, the science part is that I see little tiny things in my swing, on video, that need to be mechanically sound. When I’m not feeling as good as maybe I should, I’ll go to the film. I don’t dissect every little thing, but there are a few things I look at. Am I on time? Am I getting in the right hitting position? Sometimes when I struggle, it’s because I’m getting a little too pull-happy. So, is my barrel up, or am I opening up and my barrel is dropping?”

Laurila: Are you looking at more video, and data, than in the past? Read the rest of this entry »
