The Texas Rangers made meaningful changes this summer when they parted ways with manager Chris Woodward — Tony Beasley is currently serving in an interim capacity — and subsequently replaced Jon Daniels with Chris Young as their top front office decision-maker. But a move that has been every bit as impactful was made 10 months ago. Last November — shortly before Baseball America named him their MLB Coach of the Year — Donnie Ecker was hired away from the San Francisco Giants and given the title of Bench Coach/Offensive Coordinator.

Ecker’s reputation as a tech-and-data-savvy hitting nerd is well-earned. Prior to the two seasons he spent as Gabe Kapler’s hitting coach in San Francisco, the 36-year-old Los Altos, California native built his bona fides as an assistant hitting coach with the Cincinnati Reds, and before that as a minor-league hitting instructor in the St. Louis Cardinals and Los Angeles Angels organizations.

Ecker, who is well-educated in biomechanics and analytics, discussed some of the philosophies and practices he brought with him to Texas when the Rangers visited Fenway Park earlier this month.

David Laurila: You spend a lot of time at the ballpark, often arriving by 9 AM for a seven o’clock game. What does your day typically look like?

Donnie Ecker: “It starts with understanding where all of our people are at, zooming in on our hitters first and looking at the things that we find valuable. How is their performance aligning with our North Stars and peripherals? As a department, we want to be on top of that day-to-day. Most times, that’s a process of going deep and bringing up simple and actionable items to the surface. Everything is from the inside out, leading to what we want our conversations and training to look and feel like that day for that player. Read the rest of this entry »

The English Premier League postponed this weekend’s slate of games following the death of Queen Elizabeth on Friday. Some of you may not have known that — soccer isn’t everyone’s cup of tea — but at the same time, a lot of you did. For many FanGraphs readers, pouring a cup of coffee and watching a Saturday or Sunday-morning match is part of your routine. More often than not, it’s as a supporter of a particular Premier League team.

Brad Miller does exactly that. An ardent Manchester City fan, the Texas Rangers infielder “dove into European soccer” head-first while on the injured list a handful of years ago. What started as a diversion has turned into a passion. Miller not only keeps a keen eye on Premier League and Champions League matches, he assesses strategies and follows transfer rumors.

Style of play is a big reason he adopted Man City.

“They’re obviously really good, and I feel kind of bad admitting that,” Miller said of his initial attraction. “But they’re also a well-oiled machine. There was a documentary on Amazon, ‘All or Nothing,’ where they followed the team. That definitely had me intrigued, just watching the way they play.

“I kind of compare them a little bit to the Dodgers,” continued Miller. “They have a great market, great financial backing, and also a great infrastructure — their player-development system, scouting, medical staffs, and all that. The haven’t poured money into just purchasing players, they’ve poured it into a sustainable model.” Read the rest of this entry »

Glenn Otto is a different pitcher than the one the New York Yankees took in the fifth round of the 2017 draft out of Rice University. Acquired from his original organization by the Texas Rangers as part of last summer’s Joey Gallo deal, the 26-year-old right-hander not only has a better understanding of his craft, he’s attacking hitters with an expanded arsenal. Moreover, his five-pitch mix is directionally diverse. Augmented by an occasional bridge pitch, Otto’s offerings are designed to go north, south, east, and west.

Otto discussed his repertoire, and the education he’s received while building it, when the Rangers visited Fenway Park last weekend.

David Laurila: In what ways have you grown since coming to pro ball? Having played at a high-profile program, I assume you already had a good idea of how to pitch.

Glenn Otto: “I honestly really didn’t. I was a reliever in college and pretty much relied purely on stuff. I had a mid-90s fastball and a really good curveball, which was all I used back then. Once I got into pro ball and became a starter, it was about going as deep as I can, commanding the fastball to all four quadrants, developing a changeup — a pitch which has kind of come and gone for me — and I’ve also made some adjustments mechanically.

Most people who change employers and job titles go through an interview process, and Chris Valaika was no exception. A former big league infielder who’d been serving as the assistant hitting coach for the Chicago Cubs, and before that as their minor league hitting coordinator, he was carefully vetted before being hired as the hitting coach of the Cleveland Guardians last winter. What was that process like? He explained in an interview that was conducted earlier this summer.

———

David Laurila: You were hired by the Guardians last November. How did that come about?

Chris Valaika: “The interview process started a week or so after the season ended. I talked to [President of Baseball Operations] Chris Antonetti and then to [General Manager] Mike Chernoff. The one that really facilitated the process was Alex Eckelman, our director of hitting. We did phone to start and then Zoom with a couple of different groups. Tito [Terry Francona] was on one of them. There were some of our advance guys. There were Chris and Cherny. I also did an in-person interview with a couple of different groups. I talked to the player development department. I also worked with a hitter. I went through the whole gamut.”

Laurila: Can you elaborate on “worked with a hitter?”

Valiaka: “It was a mock. We went through the whole process of… basically, it was a workup of what I saw in the swing, and how I would address swing changes and approach.”

Laurila: This was from video?

Valaika: “Yes. And we did a mock of an in-person, as well — how I would interact in the cage to address certain things — which was to see my coaching voice, how I delivered information. We also went through advance reports and did a mock hitters meeting.

“With the hitter breakdown, it was basically me giving my 10,000-foot view of him approach-wise, bio-mechanically, things that I saw in the swing, and again, how I would address them.”

Laurila: Who was the hitter, and what did you see? Read the rest of this entry »

Ty Madden has established himself as one of the top pitching prospects in the Detroit Tigers system. Drafted 32nd overall last year out of the University of Texas, the 22-year-old right-hander has a 2.92 ERA to go with 119 strikeouts and just 88 hits allowed in 114 innings between High-A West Michigan and Double-A Erie. Moreover, he’s been especially impressive since earning an early-August promotion. Over his last four starts, Madden has fanned 29 Eastern League batters while surrendering just three runs in 22-and-a-third innings.

Earlier this summer, I asked Madden how much the organization’s analytics-driven pitching program has impacted his development.

“I’ve definitely learned a lot since coming to pro ball,” said Madden, who was still in High-A when we spoke. “Before, I knew a good amount of the information, but I didn’t really know what to do with it. The staff here has kind of taught me what these numbers mean — when they’re good versus when they’re bad — and there are also the analytics for hitters. Along with knowing your own stuff, there is the game plan and how to go against that particular lineup.” Read the rest of this entry »

The top prospect in the Los Angeles Dodgers system lost one of his baseball “brothers” a month ago. Not literally — Alex De Jesus is alive and well — but rather by dint of a trade-deadline deal. A 20-year-old infielder who’d been playing with the High-A Great Lakes Loons, De Jesus went to the Toronto Blue Jays organization, along with Mitch White, in exchange for Moises Brito and Nick Frasso.

Shortly after the trade, I asked Diego Cartaya what it’s like to have a teammate who is also a close friend leave the organization.

“It’s not easy, but I’m kind of happy for him,” replied Cartaya, who along with being L.A.’s top prospect is No. 31 in our MLB prospect rankings. “He’s going to get a better opportunity with Toronto, so we’re pretty excited for him. But it’s hard. As teammates, we spend more time together than we do with our families. He’s just like my brother.”

Cartaya’s real family is in Venezuela, and it was his father who initially taught him how to hit. The tutoring he’s received since entering pro ball at age 16 has resulted in occasional tweaks, both to his stance and his swing. Cartaya told me that he used to be “more of a big launch-angle guy,” but now has a flatter swing. Upon hearing that, I noted that the home run I’d seen him hit the previous night was more of a line drive than a moonshot. Read the rest of this entry »

Rob Refsnyder is having a career-best season with the Boston Red Sox. Playing in a reserve role, the 31-year-old journeyman outfielder is slashing .304/.380/.462 with four home runs and a 143 wRC+ in 129 plate appearances. He’s done most of his damage against lefties, boasting a robust 1.056 OPS versus opposite-handed hurlers.

He’s followed a meandering path to success. Since debuting with the New York Yankees in 2015, the University of Arizona product has played for eight different organizations, seeing big-league time with five of them. Along the way, he’s worked with numerous hitting coaches in an attempt to turn the proverbial corner as a hitter. Refsnyder entered this season with a .224/.310/.308 slash line, and six of his 10 career home runs, in 614 MLB plate appearances.

A failed quest to produce more power is part of his story. Six years ago this month, Refsnyder was quoted in a Sunday Notes column saying that he was “going to try to hit home runs… I’m going to try to completely change my game.”

Earlier this summer, I reminded Refsnyder about that conversation, then asked if he could take me through his subsequent evolution as a hitter. Here is what he had to say. Read the rest of this entry »

Mike McCarthy has followed a well-educated path in his pursuit of a big-league position. Currently the pitching coach for the Triple-A El Paso Chihuahuas, the 34-year-old Walnut Creek, California native earned a Bachelor of Science degree from Cal State Bakersfield while playing in the Boston Red Sox system, and he followed that up by earning an MBA, with an emphasis in global management, from the University of Phoenix. And he’s not done learning. Along with instructing pitchers in the San Diego Padres’ system, McCarthy is working toward a Master’s Degree in Sports and Health Science.

His educational pursuits have every bit as robust in the pitching realm. Ever since being introduced to analytical concepts as a Double-A hurler, McCarthy has strove to learn as much as he can. To say he’s made great strides in that area would be an understatement; McCarthy is one of the most forward-thinking pitching coaches in professional baseball.

David Laurila: You’re big into pitching analytics. When did that start?

Mike McCarthy: “One of the moments I remember, one of the most distinct, is Brian Bannister coming to Portland. I believe that was in 2015. I was throwing a bullpen, and I asked Brian, ‘Why does Justin Haley get so many swings-and-misses on his fastball?’ I told him it seemed like an invisi-ball, and none of us could figure it out. He said, ‘We’re learning about this thing called spin rate, and his is really high. ‘I was like, ‘What the heck is that?’

“There was a saying that Anthony Ranaudo, Brandon Workman and Drake Britton were all using. They called it ‘elevate and celebrate.’ While I was throwing fastballs down and away, those guys were throwing fastballs up and getting swings-and-misses. That was kind of going against the grain at the time, and it turns out they all had high-carry fastballs. We just didn’t know what it meant.

“That was the first time I really started to ponder the idea, ‘What are we missing? What don’t we know yet?’ Since that time, baseball has obviously delved into the technology and analytics, and that’s something I’ve enjoyed using as a part of the way I approach coaching.”

Laurila: When did really start to dive in to analytics? Read the rest of this entry »

Mitch White brought a new-ish slider to Toronto when the Blue Jays acquired him at this year’s trade deadline. He also brought a nerdy approach to pitching. That should come as no surprise. The 27-year-old right-hander had pitched in the Los Angeles Dodgers system since being selected in the second round of the 2016 draft out of Santa Clara University.

White also had a big-league resume when he changed organizations. Having debuted with the Dodgers in August of 2020’s COVID-truncated campaign, he had 105-and-two-thirds innings under his belt when the four-player swap occurred. Since coming to Toronto, White has a 5.89 ERA over four starts.

White discussed his new and old sliders, and the blister issues that have dogged his career, when the Blue Jays visited Fenway Park last week.

On his path to the big leagues and dealing with blisters:
“A lot of it was staying healthy. I’ve had a few things go on every year, whether it was blisters or some back stuff. I had a broken toe at one point. Right now, I have this little guy [blister]. The slider really puts a lot of pressure there because I’m trying to get to the side of the ball and spin it, and for whatever reason, I guess my skin is soft. I’ve had to learn how to manage that stuff in between outings. Read the rest of this entry »

Friday’s interview with Michael Harris II focused on his career path, the 21-year-old Atlanta Braves rookie having excelled as a multiple-sport athlete while growing up in Stockbridge, Georgia. Moreover, he’d been a two-way player whom many scouts preferred as a pitcher. While baseball and outfielder-only are proving to be prudent choices, he had options along the way.

Jordan Romano’s path shares some similarities with Harris’s. Not only was the Toronto Blue Jays closer a multi-sport athlete in his formative years, he originally excelled as a position player. That he became a pitcher was circumstantial. Choosing baseball was a matter of passion.

“Being Canadian, I played a lot of hockey in high school,”said Romano, who grew up a Toronto Maple Leafs fan in Markham, Ontario. “I also played a little basketball and was pretty decent at volleyball. But with baseball, you kind of had to drag me off the field, even in practice. My parents wanted me to play a bunch of different sports, and while I really enjoyed hockey — I still do — I didn’t have the passion for it that I did for baseball.”

Romano never considered himself NHL material, but he does feel he had the potential to play collegiately, or in juniors, had he stuck with it. The decision to forgo that possibility came at age 17, and while it shaped his future, it didn’t end his time on the ice. Romano kept lacing up the skates for another year.
