For one month early in the 2015 season, Rick Porcello, traditionally a sinkerballer whose fastball sits at 91, led with the four-seam. It was only the second month in Porcello’s career in which the sinker’s position as his primary pitch was usurped by the four-seam, and unlike the other instance of this happening, the magnitude of the shift was noticeable.

It was the beginning of Porcello’s tenure in Boston, his new home after spending the first six years of his career in Detroit, and so at the time, it seemed like focusing on incorporating the four-seam fastball might’ve been part of the early organizational roadmap for Porcello. But the experiment didn’t go well. In eight four-seam-reliant starts, Porcello allowed 31 earned runs in 48 innings, good for a 5.81 ERA and a 4.76 FIP. All of his patented ground balls went missing, his home-run rate ballooned, he walked more batters than usual, and just like that, the four-seam trial run was over. Back to the sinkers he went.

If it really was an organizational thing — that the Red Sox encouraged Porcello to use his four-seam fastball more early in the season, if not just to see what it was like — it doesn’t seem like a bad idea, results notwithstanding. Even though Porcello’s “heater” only sits at 91, he has the ability to ramp it up to 96, and even more important than that, he’s able to naturally generate more spin on his four-seamer than almost any pitcher in baseball. We know that high-spin fastballs can be effective when located up in the zone, even without velocity, and so Porcello seems to possess a real weapon with his high-spin heater.

For whatever reason, though, the plan didn’t work, and so it didn’t stick. Maybe it was command, maybe it was comfort, maybe it was the way relying on the four-seamer affected the rest of his sequences, or maybe it was something else entirely. Whatever the case, Porcello went back to the sinker being his primary pitch, and he hasn’t looked back since. But the four-seamer is still there. And the way he’s using it now is making it more effective than ever. The idea to employ a four-seam approach may not have gone as smoothly as originally planned, but it looks like it’s working itself out anyway.

One might be inclined, instead of opting for this game, to choose the one which features the Rays and Marlins, on account of that contest offers not only (a) two reasonably compelling starters but also (b) one of the very best center-field cameras in all of baseball. As opposed to this game, that is, which features two compelling starters, as well, but one of the worst center-field cameras. Unless there have been developments in the meantime, that is. In which case: ignore this entire brief entry. Whatever the case, the consequences are almost non-existent and we’re an embarrassment to our ancestors.

Mike Clevinger was nervous when he made his major-league debut with the Cleveland Indians last Wednesday. As a matter of fact, he was so nervous that he vomited prior to taking the mound. That didn’t prevent him from pitching well. The 25-year-old right-hander allowed just one run through five innings before faltering in the sixth. He wasn’t involved in the decision, but his club did come out on top in a 12-inning affair played in Cincinnati.

A fourth-round pick by the Angels in 2011, Clevinger came to Cleveland in the 2014 deal that sent Vinnie Pestano west. Prior to being called up, the impressively coifed native of Jacksonville, Florida, was 5-0 with a 3.03 ERA at Triple-A Columbus.

Clevinger talked about his debut outing — primarily his emotion-filled first inning of work — when Cleveland visited Boston over the weekend.

———

Clevinger on his mindset when he took the mound: “I remember trying not to look up. I was trying to just zone in on the catcher. Ever since I got to pro ball, what I’ve heard is, ‘Whenever that time comes, don’t look up. If you do, the moment will get you out of yourself. So all I thought was, ‘Stay within yourself, stay within yourself; don’t overthrow, don’t overthrow.’

It doesn’t require a brain surgeon to recognize that a game featuring two of the league’s more successful pitchers and more successful clubs — that such a game would possess some interest for the public. There’s also no reason to believe, however, that a medical doctor trained specifically in the field of neurology would be particularly well-suited to diagnosing the likely aesthetic value of such a game. There are a number of neurosurgeons, presumably, who have almost no familiarity with the Pastime. Like Nate’s dad, for example. He’s a neurosurgeon, but what does he know about sport? Nothing, is what.

The numbers suggest that Khris Davis should be labeled a power hitter. Since the beginning of last season, the Oakland outfielder is hitting .244/.308/.504 with 39 home runs in 603 plate appearances. This past week, he had a three-homer game capped off by a walk-off grand slam.

A few days before his heroics, I opined to Davis that he’s best described by said label. He demurred.

“That’s arguable,” answered the 28-year-old former Brewer. “It’s just what everybody’s judgment is of me. I don’t think I’m a power hitter.”

Color me a skeptic. Not only is Davis among the league leaders in home runs this year, he went deep 21 times over the second half of last season. If he’s not a power hitter, where are the bombs coming from? Read the rest of this entry »

Smyly (49.2 IP, 85 xFIP-) vs. Fulmer (19.1 IP, 85 xFIP-)
The virtues of Drew Smyly as a pitcher are what Thomas Jefferson — and also anyone who possesses some facility with English — might describe as “self-evident.” As for Michael Fulmer’s virtues as a pitcher, those are decidedly less evident at the moment. Because one of the things he’s done is to concede earned runs at a rate about 50% higher than an average pitcher. By this measure, his virtues are rather obscure. But look: he’s produced a fielding-independent line that’s roughly a standard deviation better than the average starter’s. And a sitting fastball velocity more than a standard deviation better. And he’s also more than a standard deviation younger than the average starter. The marginal return on your psychic investment in Michael Fulmer is likely to be enormous. Thanks to Michael Fulmer, you’re going to be flush with psychic currency.

Marcell Ozuna is the third-best outfielder on his team. He can’t match the power and discipline of Giancarlo Stanton, and he can’t match the patient, contact-oriented approach of rising star Christian Yelich. Partially related to those two statements, Yelich and Stanton have signed contracts worth nearly $400 million total while Ozuna, despite possessing more service time than Yelich and having played 50 more games than Stanton since the start of 2014, will be paid near the league minimum this year. Ozuna is off to a great start this season, and we might want to look for changes to his game after a rough 2015 season, but Ozuna is very much a similar player to the one that slugged 23 homers back in 2014.

Ozuna has a fairly unique game. He has good power, but in more than 1500 plate appearances, it has only shown up as average with a .157 ISO. He walks at a below average rate (6% for his career), strikes out at a below-average rate (23% for his career), and has maintained a high .331 BABIP. Together, it has made him a roughly average offensive player, and a difficult home park elevates his wRC+ to 104. Not too bad. On defense, Ozuna has recorded nearly 3,000 innings in center field and both UZR and DRS place him right at average. Average offense and average defense in center field combine for an above-average player. Average to above-average might sound a bit boring, but Ozuna’s streaky performance and perceived inconsistency means he gets to his stats in rather exciting fashion.

Ozuna has had one really good year, in 2014, followed by a disappointing season in 2015 that saw him receive a demotion in the middle of the season, although that demotion might have been tied more closely to Ozuna’s super-two status and his agent Scott Boras rather than any strict performance-related deficiencies. This season, Ozuna is back, picking up where he left off at the end of 2015 and playing like the player who exhibited so much promise two seasons ago. How long will this last? It’s hard to say.

Yes. What is wrong with Matt Harvey? Because if you watch him pitch, it seems like everything is wrong, and yet nothing at all. At least, it’s hard to put your finger on it. You run down the list of things that could explain why he has an ERA near five and the worst ERA estimators of his career, and you find little things here or there. But do you find a smoking gun?
