It seemed like this post was practically going to be able to write itself. Hanley Ramirez has been hot at the plate, and he’s tied for the big-league lead in homers, with 10. There are hundreds of hot streaks by so many players every single season, but this year we have the treat of new data, and Ramirez’s has seemed particularly remarkable. I thought this would be simple and straightforward, but instead we have something more complicated and kind of boring to what I assume would be the majority of people. Keep reading, though! There’ll be some .gifs. You love .gifs.

If you’ve paid attention to Gameday, you’ve probably noticed that we’ve started to get some early-season batted-ball data. It hasn’t been complete, but it’s been fairly consistent, as one of the first signs of the rolling out of StatCast. It can be tricky to find and preserve that information, but thankfully for the masses, there’s Baseball Savant, which I feel like I must link in every post. There, for the first time, we can sort hitters by batted-ball velocities. The industry has had HITf/x for years, so this isn’t progress for them, but it’s progress for us, on the outside. And we all love a new toy.

The Boston Red Sox rotation began the season with some scrutiny as the starting five was filled with average to above average types and no pitcher resembling an ace. That scrutiny has turned to criticism as we near the end of the first month of the season and that rotation has allowed more runs than any other starting group in the American League and their 5.75 ERA is the worst in Major League Baseball. The rotation has gotten off to a terrible start, but the offense has produced and the Red Sox will still enter May with a winning record at 12-10. While a bloated ERA has generated calls for the Red Sox to make a trade for a starter, the current rotation has pitched better than its ERA would indicate. Going forward, the Red Sox rotation should get much better results than we have seen so far.

The Red Sox have given up a lot of runs, but the rotation’s FIP is a middle of the road 3.91. The Red Sox and Cleveland Indians are the only two rotations in MLB to have their ERA and FIP differ by more than one, and for the Red Sox that number is 1.84. The team’s walk rate at 8.8% is a little too high, but they make up for the high walk rate by striking out 22.9% of hitters. Their 14.9% K-BB rate is in the upper third of American League teams. Individually, there is not a single starter with a lower ERA than FIP.

Episode 554
Touki Toussaint is a right-hander in the Arizona system who was selected 16th overall in the most recent draft. Brian Johnson is a left-hander in the Red Sox system, currently playing for Triple-A Pawtucket. This edition of FanGraphs Audio features both of them, in conversation with lead prospect analyst Kiley McDaniel. (Note: Toussaint’s interview begins at about the 12:45 mark; Johnson’s, around the 20:35 mark.)

As of March 16th of this year, everything was decidedly not sweetness and light for Boston right-hander Joe Kelly. On that day, he recorded his third (and ultimately final) start of spring training, over the course of which he conceded three runs in just 2.2 innings, bringing his spring ERA to 11.05. Worse yet, he was compelled to leave that start due to biceps tightness in his biceps (i.e. the place where that kind of tightness is most commonly found). The outlook was sufficiently grim that managing editor Dave Cameron was forced to publish a post here considering other starting possibilities for the Boston Red Sox.

Following a retroactively dated trip to the disabled list and a pair of minor-league spring-training appearances, Kelly made his season debut on Saturday. It’s hard to know what Kelly’s expectations were or what the organization’s were, but “low-ish” is an objectively reasonable assumption. If nothing else, there had to be concerns regarding Kelly’s endurance. Of the two appearances he’d made since leaving his spring start with an injury, his highest pitch count was 78. “Ideally he’d have another outing to build arm strength before an MLB game,” John Farrell said in the presence of Providence Journal reporter Tim Britton. That ideal scenario did not become a reality. Instead, Kelly’s next appearance was Saturday’s.

There were reasons, in other words, to expect the worst for Joe Kelly’s start on Saturday at Yankees Stadium. In reality, however, Kelly’s results from that start were actually the best. Not the best in every sense of the word, but certainly among the best so far as Kelly’s major-league career is concerned. He allowed just one run over 7.0 innings. He posted the lowest single-game FIP (41 FIP-) of all his starts ever. And another thing he did was to surpass his previous single-game strikeout mark. Previous to Saturday, he’d recorded six strikeouts in a single game on seven different occasions. On Saturday, however, he produced eight strikeouts (i.e. two more than ever before).

The Red Sox have played one game this season. Seems like it’s time to check in on Dustin Pedroia. Before you go, assuming the rest of this is going to be stupid, at the very end there is a poll. Internet readers love polls. Please vote in it only after you at least glance over what’s in between. So: Dustin Pedroia has two home runs!

Already, that says something. Pedroia, last year, hit seven home runs. He went deep twice on Monday against the ace to whom the Red Sox have been most frequently linked in trade rumors. Now, Pedroia wasn’t the only Boston player to go deep, so, maybe it was just one of those days. Yet it wasn’t just that Pedroia homered. It was also how Pedroia homered. His homers looked like classic Pedroia homers, and that’s just the thing.

The Red Sox clearly have a thing for Justin Masterson. They drafted him with their second-round pick in 2006, then developed him into one of their best young pitching prospects before the Indians demanded him as part of the Victor Martinez trade in 2009. This winter, when he was finally a free agent after spending six years in Cleveland, the Red Sox took the opportunity to bring him back to Boston, signing him to a $9.5 million contract for 2015 despite the fact that he posted a 5.88 ERA last season.

The organization’s affinity for Masterson’s skillset is noteworthy, because this week, the Red Sox signed Rick Porcello to a four year, $82.5 million contract extension on the bet that Porcello is essentially a younger version of this same type of pitcher.

First, let’s do a quick comparison. Here are Masterson and Porcello’s numbers from their age-23 through age-25 seasons, which in Porcello’s case covers the last three years.

Both Porcello and Masterson were pitch-to-contact groundball hurlers, with Masterson getting a few more grounders and strikeouts at the expense of a walk rate that was significantly higher than what Porcello has posted. They’re not identical, but they’re cut from the same cloth, and heading into their mid-20s, the results were quite similar. By ERA, both were roughly league average starters, though metrics that attempt to eliminate defensive performance from the picture both thought they were significantly above average, with Porcello being slightly ahead of Masterson at the same point in their careers.

Following a stupid .451/.491/.804 performance in the Grapefruit League, the hype surrounding Red Sox outfielder Mookie Betts is through the roof. Scouts are all but penciling him into July’s All-Star lineup, and some of Betts’s peers have even gone as far as to compare him to Andrew McCutchen. And wouldn’t you know it, Betts opened the 2015 season by going 2-4 with a homer and a walk on opening day. Mookie-mania is upon us.

Here at FanGraphs, we’ve been on the Betts bandwagon for a while. Carson Cistulli’s been tracking Betts since July 2013, when he made his first appearance on one of his fringe five lists. An undersized 5th round draft pick with excellent stats, Betts was exactly the type of prospect who endears himself to prospect enthusiasts whose heads are buried in spreadsheets. At that point, Betts was merely a little-known A-Baller with an unusual name.

But last year, Betts took his act to Double-A, and kept right on hitting. He put up a 177 wRC+ in two months in Double-A, and followed it up with a 158 mark in Triple-A. The 5-9 second baseman with the funny name was starting to look like a bona fide prospect, and it was happening in a hurry.

Beating the rest of the league to the punch with a large contract extension for Rick Porcello when much better players await in free agency is not going to garner excitement or plaudits, but the Red Sox are anticipating an expensive free agent market in 2016 and providing themselves a safety net. Boston resorted to Plan B before they knew if Plan A would work, but the Red Sox can still implement Plan A and sign a big-name free agent while simultaneously providing depth for their rotation. Five years and $95 million is a lot of money for a player without a world-beating track record, but Porcello has been good and reliable and he is still just 26 years old. This contract is not all that surprising as Mike Petriello predicted a similar contract in February.

Last year, three pitchers signed extensions just a year away from free agency and one of them is apt for Porcello. Clayton Kershaw’s seven-year, $215 million contract is way too big, Charlie Morton’s three-year, $21 million contract is too light, but Homer Bailey’s six-year, $105 million contract (with an option for a seventh year) is right in the same range as Porcello. Bailey was two years older and only twice pitched over 150 innings while Porcello has exceeded that mark in six straight seasons. Bailey was coming off the better season, with around four wins in 2013, but he also received more money with greater risk of injury. According to Jeff Zimmerman’s disabled list projections, Porcello is the second most likely starter to make it through the season without a stint on the disabled list.

Even if we treat Bailey as an outlier for an extension, last year’s free agent class has a pretty close contract to Porcello’s: James Shields, who signed for four years and $72 million with the Padres. Shields has the better track record, but he’s headed into his decline years while Porcello is headed into his mid-20s. While Shields’ deal ends when he’s 36, the Red Sox have only committed to Porcello up to age-30.

And now the final division preview, just in time for Opening Day. If you missed them, here are the first five:

NL West
AL West
NL Central
AL Central
NL East

Now, wrapping things up with the AL East.

The Projected Standings

The only division in baseball where all five teams have a legitimate shot at winning; the projected spread between first and last place in the AL East is smaller than the gap between first and second place in the NL East. The forecasts have a favorite, but this division is wide open, and nearly any order of finish could be reasonable. On to the teams themselves.

This week’s nuttiest pitches might even have a point. But let’s just start with the GIFs. Because it’s fun to watch crazy pitches do crazy things.

Let’s do the uncle charlies, the yakkers, the yellow hammers — curveballs are on the menu today. As usual, we’re looking at the last three years because that’s what MLB.tv allows us, and we’re sorting PITCHF/x to find the pitches with the most extreme horizontal and vertical movement, as well as velocities.
