Tanking is a problem. Professional sports like baseball are built on the assumption that both sides are trying to win. Organizations putting forth less than their best efforts hurts the integrity of the sport and provides fans with little reason to engage. That said, the perception of tanking might have overtaken the reality of late. Competitive imbalance is not the same as tanking. Sometimes teams are just bad, even if they are trying not to be.

Tanking concerns are not new. Two years ago, just after the Astros and Cubs had turned their teams around, the Phillies were attempting to dismantle their roster by trading Cole Hamels. The Braves had traded multiple players away from a team that had been competitive. The Brewers, who traded away Carlos Gomez, would soon do the same with Jonathan Lucroy after he rebuilt his trade value.

The Braves, Brewers, and Phillies all sold off whatever assets they could. Two years later, though, those clubs aren’t mired in last place. Rather, they’re a combined 54-37 and projected to win around 80 games each this season in what figures to be a competitive year for each. While the Braves and Phillies could and/or should have done more this offseason to improve their rosters, neither resorted to an extreme level of failure, and the teams are better today than they would have been had they not rebuilt. While accusations of tanking dogged each, none of those clubs descended as far as either the Astros or Cubs. None came close to the NBA-style tank jobs many feared.

One might suspect that I’ve cherry-picked the three clubs mentioned above, purposely selecting teams with surprising early-season success to prop up a point about the relatively innocuous effects of tanking. That’s not what I’ve done, though. Rather, I’ve highlighted the three teams Buster Olney cited by name two years ago — and which Dave Cameron also addressed — in a piece on tanking.

Between West 124th and 125th Streets on St. Nicholas Ave. in Harlem rests a street-level commercial space situated between a Dollar Tree and a Chuck E. Cheese’s, and it is where Adam Ottavino might have saved his career last winter.

The space was a solution to a problem. He lived in the city in the offseason with his wife and two-year-old daughter. In previous offseasons, he had traveled out to Long Island to work and throw at a facility, but the commute and practice time away was beginning to strain his family.

Moreover, Ottavino’s previous throwing partner, Steven Matz, had left the city and moved Nashville, Tenn., after becoming engaged. Finding a throwing partner and facility in Manhattan, the most prized real estate in the country, wasn’t easy. He knew Matt Harvey was one of a few major-league pitchers living in the city in the offseason, so he asked Harvey if he was interested in finding a place to throw, but Harvey declined.

“At that point, I was kind of screwed,” Ottavino said. “I didn’t know what to do.”

Ottavino, a Brooklyn native, required a productive offseason. He was left off the Rockies’ Wild Card roster weeks earlier after an awful 2017 season when he walked nearly seven batters per nine innings, leading to a 16% walk rate. He was in the final year of his contract. He had spent some time at Driveline Baseball after the season ended. He thought he had now had some solutions. He had bought tens of thousands of dollars worth of equipment with which to try and make himself a better pitcher. But he needed a place to experiment.

PITTSBURGH — As defensive shifts — or, at least, infields shifts — have become an everyday part of the game, it takes a lot to get our attention. The Diamondbacks’ shift against Rockies second baseman DJ LeMahieu last season got our attention.

In case you’ve forgotten, borrowing from a post from last season detailing the alignment:

That gets our attention.

A favorite question of the baseball audience is, when does a small sample start to have meaning? There are a few general rules of thumb, but in large part it’s still a question, I think, because there is no perfect answer. It can be a gut thing, or it can be a matter of magnitude. I don’t care if a batter starts out 6-for-10 with three home runs. I’d care a lot more if a batter were to start out 8-for-10 with six home runs. Some performances over small samples are so very good — or so very bad — that there almost has to be signal. Even over a short amount of time, it’s hard for a player to fluke his way into the extremes.

Over the winter, the Rockies invested heavily in their bullpen. You could argue they invested *too* heavily, but, well, this is the bullpen era, and you’d figure the Rockies, of all teams, might need to keep theirs both deep and refreshed. It’s a bullpen with plenty of interesting arms, but the most important reliever might be Adam Ottavino. In the past, Ottavino has been genuinely dominant. Last season, he came off the rails, with a walk rate of 16%. With a bad Ottavino, the Colorado bullpen might not be a strength. With a good Ottavino, it would go four or five deep.

It’s early. But, as early as it is, Ottavino has faced 34 batters, and he’s struck out 22 of them. He’s walked one guy, he’s allowed one run, and he’s given up two hits. Nearly half of all swing attempts against Ottavino have missed. Nearly half of all swing attempts against Ottavino pitches in the strike zone have missed. Only Josh Hader might rival what Ottavino has done. This is a small sample that’s so good, it’s crying out to be investigated.

The results are almost unbelievable. It turns out Ottavino also has an exceptional process.

I don’t know if Charlie Blackmon is baseball’s most underrated player. Probably not. There are a lot of very good players. But just in case you don’t know exactly what’s up: Last season, Blackmon finished ninth among position players in WAR. Over the past three seasons, Blackmon has ranked 22nd, between George Springer and Kyle Seager. Blackmon is a center fielder who just finished with a top-30 expected wOBA. The year before that, he was in the top 40. Charlie Blackmon is very good, and, depending on your own personal thresholds, you might well say that Charlie Blackmon is great. He’s been lined up to be a part of the upcoming massive free-agent market.

But Blackmon has decided to take himself off the market entirely. Or, the team and the agency have decided, with Blackmon’s final approval. You don’t often see premium free agents sign extensions so close to the end of a contract, but Blackmon has agreed to an extra five years with the Rockies, with a $94-million guarantee. It’s more complicated than that, but the take-home point is that Blackmon is going to stick around in Colorado. Clearly, he’s fond of it there, and he’d hardly be the first player to decide that free agency appears less appealing than it used to.

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 slider 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 the second installment of this series — Part 1 can be found here — we’ll hear from three pitchers — Kyle Freeland, Jim Johnson, and Kris Medlen — on how they learned and/or developed a specific pitch.

Kyle Freeland (Rockies) on His Changeup

“I never really threw a changeup in college. When I got into pro ball, that was our main focus to help me develop throughout the minors and get to this point. We had to find a grip that I was comfortable enough with to throw it in any count.

“It took some time. I probably went through half a dozen different grips before I finally found one that fits me, that works with my arm slot and my arm speed. It wasn’t until the end of last season that I finally found what I think works best. I had one that was working well for awhile, but it kind of tapered off. I wasn’t really comfortable throwing it off my ring finger and my pinky finger. Read the rest of this entry »

Pitchers learn and develop different pitches at varying stages of their lives. It might be a curveball in high school, a cutter in college, a slider or split-finger fastball 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. As the quality of competition improves, a pitcher frequently needs to optimize his repertoire.

In the first installment of this series, we’ll hear from Jeff Hoffman, T.J. McFarland, and Drew Smyly on how they learned and/or developed a specific pitch.

Jeff Hoffman (Rockies) on His Slider

“The one pitch in my repertoire that I haven’t thrown my whole life is my slider. I picked that up in college. It actually started as a cutter, but I couldn’t really keep it small, like a cutter, so it turned into a slider. I’ve kind of just hung with it through the years, embracing it as a slider.

Recently, I posted notes on Cleveland ace Corey Kluber to give readers some idea of what a pitcher of such obvious talent looks like on a scouting report. Well, I recently ran into Rockies righty German Marquez — a 55 FV on his final FanGraphs prospect list and a 2.5 WAR pitcher as a rookie (which is a 55) — so here’s a similar rundown.

Marquez’s body looks like it’s backed up a bit, but he was still generating premium velocity with ease, sitting 94-96 with his fastball throughout my viewing. It, along with his low-80s curveball, is comfortably plus, and he threw several 70-grade curveballs. Marquez is clearly working on developing two other pitches — an upper-80s slider and mid-80s changeup — that are both below average right now. The change has promising movement, Marquez just lacks feel for it.

Marquez barely threw anything other than his heater and curve last year and was able to succeed anyway because they’re both excellent. If a tertiary offering is his focus this year, it’s reasonable to expect some growing pains and regression, though this is probably best for his long-term development. His fastball velocity has fluctuated a bit this spring (as low as 92 in other outings), but that’s to be expected.

He’s not technically a prospect, but Rockies righty Jairo Diaz looks poised to make an impact in the bullpen this year. Diaz missed all of 2016 and most of 2017 due to Tommy John, but his stuff has been vicious this spring. In two looks at him, Diaz has been 96-99 with a plus slider in the 87-90 mph range.

Manny Margot upped his launch angle more than any other player in the second half of the 2017 season. Eno Sarris wrote about that fact in January, and as he did so with data alone, a not-insignificant piece of information remained unaddressed: How purposeful was the change, and what (or who) prompted it?

The answer to the latter question is Johnny Washington. San Diego’s assistant hitting coach made the suggestion, and knowing that “hitting the ball in the air gives you more chances in the gaps,” Margot took it to heart.

The 23-year-old outfielder confirmed that “right around the halfway point” is when he began trying to hit more balls in the air. The ways in which he accomplished that goal were twofold. Read the rest of this entry »
