As a RotoGraphs reader, I’ve always enjoyed Joe Douglas’s “Buying Generic” series. In past articles, he has compellingly compared “generic” players like Ryon Healy, Logan Forsythe, and Justin Bour to “brand name” ones like Jake Lamb, Jason Kipnis, and Carlos Santana.

The fantasy relevance of the exercise is obvious: Buying generic allows owners to acquire players cheaply and with relative ease, instead of paying a premium (whether in a trade or in a draft or auction) for a brand-name player.

For today’s comparison, we’re going to analyze two players who have played in parts of the last three seasons, but neither has eclipsed 350 plate appearances in any one year. Both appear on their way to full-time jobs in 2017 and beyond.

Here’s how Mr. Generic and Mr. Brand Name have fared since 2015:

Cody Bellinger has been superb in his call up with the Dodgers, hitting 6 home runs in 65 plate appearances. With Andrew Toles out for the season with a torn ACL, the likelihood of Bellinger staying in the big leagues has improved. However, what should reasonably be expected for the Dodgers phenom for the rest of 2017? It doesn’t take an advanced statistician to understand that the .446 wOBA he has posted thus far will regress, but the question is how far? Does Bellinger’s performance line up with what was expected? The first place I want to start is with Bellinger’s scouting report courtesy of our own Eric Longenhagen. (Trimmed it down a bit)

…That power comes from the monster hacks that Bellinger takes in all counts. He doesn’t protect or shorten up with two strikes and instead he’s constantly threatening low-flying aircraft with his incredible torque, hand speed and uppercut swing. This results in lots of airborne contact (majestic blasts as well as weak pop ups) and plenty of strikeouts… Bellinger has shown the ability to stay back on breaking balls, as well the ability to turn on plus velocity in on the hands and, while he does try to pull everything, he has solid plate coverage…

He’s also seen time in the outfield, including center, and there are scouts who think he could play all three outfield spots in a pinch…

There’s some risk here because of the swing and miss, and I expect major-league pitchers will feed Bellinger a steady diet of offspeed pitches, especially back-foot sliders, once they see the swings he takes…

Jeff Zimmerman has already dived into Bellinger’s defense in the OF, which may be better than expected. While defense isn’t really pertinent to our discussions for ottoneu/fantasy, (Bellinger has already secured OF eligibility for 2018), Jeff does good work. If you’re not reading it, you’re missing out. Read the rest of this entry »

If you’ve tuned in before, you know what this is about. If not: the Small-Sample Normalization Service (SSNS) seeks to, ah, normalize a player’s performance in the context of his own previous achievements (or lack thereof). Most of us are human, and our humanity leaves us vulnerable to the biases that cloud rational thought and critical analysis. Such vulnerability is eagerly exploited by the small sample size, never more so than in April. While midseason small samples cower under the cover of hundreds more plate appearances, April performances have no such luxury.

A month’s worth of playing time is certainly more worthwhile to assess than one week’s worth, but 30 innings or 100 plate appearances can still be pretty volatile. Here are a few still-small samples that recently caught my eye.

All graphs pulled prior to yesterday’s games.

It’s time to understand how ownership trends are playing out this year. I will start by breaking down one of the most common fantasy sites, ESPN. I will go over the batter ownership rates for different league sizes so owners know which players are applicable to them. Additionally, I will find the current replacement level player for each position.

With fantasy experts using ownership rates to help find potential waiver targets, it is important to know each league’s ownership level. Historically, I know I should only worry about players owned in 10% of leagues or less but not everyone plays in 15-team or deeper leagues.

At the time of this writing, there are 37 major league hitters with a wRC+ of 150 or higher. There are the usual suspects: Bryce Harper, Mike Trout, and Nolan Arenado are on the leaderboard to no one’s surprise. There are exciting young prospects, including Mitch Haniger, Aaron Judge, and Joey Gallo. Then there are unexpected names like Eric Thames, Cesar Hernandez, and Robbie Grossman.

Lengthy articles could be, and have been, written about any of the players above. One player who hasn’t received much publicity despite some relatively prolonged success is Grossman.

He checks in with a 158 wRC+ in 67 plate appearances so far this year. Steamer projects a .322 wOBA and 99 wRC+ for the rest of the season (ROS), and that projection puts him just a few ticks behind his highly-touted teammate Max Kepler. Although Kepler is three years younger and may have a higher ceiling, the point is that name recognition can play a pretty big role in how we analyze players.

Also, Grossman used to be bad. From 2013 to 2015, he had just a .281 wOBA and 77 wRC+ in 202 plate appearances against left-handed pitching, despite being a switch hitter. Since 2016, however, Grossman has a .417 wOBA and 166 wRC+ in 170 plate appearances against lefties. Even with his early-career struggles against lefties, Grossman now has a lifetime .344 wOBA and 118 wRC+ against them. Read the rest of this entry »

Last week, I inaugurated RotoGraphs’ Small-Sample Normalization Services, or SSNS. Said services attempt to contextualize good and bad starts within a particular player’s history of achievements (or lack thereof). Assessing player performance based on small samples seems distinctly difficult in April, when, for whatever reason, we perceive players with tattered histories as blank slates. Occasionally, there’s merit to these perceptions. More often, we find out a player’s April is no different than his May or June or July, for example, when a small-sample performance might go less noticed than it would when starting from zeroes.

Here are a handful of players that have caught my eye lately.

Name: Jason Vargas, KCR SP

Starling Marte was suspended for 80 games on Tuesday after testing positive for Nandrolone back in Spring Training and then losing the subsequent appeal. Let’s be honest, the first thought for most of you was how it impacts your fantasy league, whether you have Marte or not. Replacing him will be no easy feat. He was a firm second rounder all draft season, going at pick 23 on average and falling no lower than pick 36 in NFBC drafts.

Despite losing 10 homers off his 2015 total, he still finished as the fifth-best outfielder last year according to ESPN’s Player Rater. Over the last four seasons, Marte has averaged 13 HR and 37 SB with a .292/.349/.448 line despite only once playing more than 135 games (153 in ‘15). He is coming off a career-high 47 SB and has at least 30 in each of the four seasons. Speed is the driving force behind his value and will be the toughest aspect replace. We’ll look at the potential in-house replacements as well as a group of available outfielders at the various sites worth considering.

IN-HOUSE

Austin Meadows, the team’s top prospect, was the first name to cross everyone’s mind when they heard about the suspension. However, GM Neal Huntington has suggested that Meadows isn’t quite ready just yet:

Just before the season started, the FanGraphs staff (including RotoGraphs contributors) was asked to make its official predictions for the upcoming season. We took our best shot at predicting the playoff teams, MVP and Cy Young Award winners, and Rookies of the Year for 2017. Perhaps in the coming weeks we will check in with the top picks for MVP and Cy Young, but in this article, we’re going to look at the top rookies.

Our staff picks on the American League side had Andrew Benintendi (40 votes) as the overwhelming favorite to be named the league’s top rookie, with Jharel Cotton (4) and Mitch Haniger (4) rounding out the top three.

Over in the National League, Dansby Swanson (27 votes) was the favorite by a wide margin, followed by Robert Gsellman (12), Manuel Margot (5), and Hunter Renfroe (4).

While it’s extremely early and still much too soon to make any concrete statements about who will win this year’s awards, let’s take a look at the wide-ranging early season performances of the players we expect to be the game’s top newcomers: Read the rest of this entry »

With about a week of 2017 baseball data in the books, there are already thousands of innings, plate appearances, and batted balls to parse through. We’ve seen a perfect game bid, a cycle, multi-home run performances, and a huge lead blown in the ninth. Unfortunately, something else we’ve seen are injuries to key players. Like the crack of the bat and pop of the glove, injuries are a part of the spot. They’re bad for the player, the team, the fans — and fantasy owners.

When a key player on your fantasy roster gets injured, it often leaves you scrambling to fill the unexpected hole. The following exercise is designed to help you survive such situations. We’re going to look at viable players who are readily available in most fantasy leagues. To qualify for this list, a player must be owned in less than 50% of all Ottoneu fantasy leagues, based on the Ottoneu Average Salaries page. He also must be able to help your team right now (i.e., no prospects).

Getting right to the list, here are of five players worth a shot in an emergency who are owned in less than 50% of Ottoneu leagues, along with their positional eligibility, average salary, and owned percentage: Read the rest of this entry »

I don’t mean to over-hype anyone. Or maybe I do. I don’t know. I seek to provide an adequate amount of hype and keep things in perspective. That said, I’m pretty excited about Josh Bell. You may know him, you may not; he’s slated to be the Pirates’ primary first baseman, maybe with a little bit of backup outfielding thrown in. Josh Shepardson talked about him and his general skill set in November. Bell’s young and a several-time top prospect, although the highest he ever reached on any given list was MLB.com’s, at No. 34 overall prior to 2015. Nothing to sneeze at, but he never carried the same hype as, say, Yoan Moncada currently does. He’s Eric Longenhagen’s No. 50 prospect this year and KATOH’s No. 25. Knowing the gory math that goes into KATOH, I’m very partial to it. Also, all of this suggests I’m not early to any kind of party here. I’m reluctant to claim as much. I just can’t help but produce my own tributes every now and then.

Bell walked more than he struck out last year. As a rookie. That’s what gets to me. Not that it’s never been done before, and it’s not like it was a huge sample size — 153 plate appearances. I found plenty of examples in the last 25 years to compare; Bell’s rookie season is almost a dead ringer for that of Doug Mientkiewicz, a first-ballot Surname Hall of Famer but otherwise mediocre ballplayer with a decent three-year peak.

Where Bell diverges from Mientkiewicz — and everyone else, for that matter — is his hard-hit rate (Hard%). Mientkiewicz decidedly did not hit the ball hard. Among rookies since 2002 (because that’s as far back as our batted ball data from Baseball Info Solution dates) who notched at least a .130 isolated power (ISO), none hit the ball as hard as Bell. Again, small samples, but this is already a decent list to top.

When we expand the sample from rookies to all hitters in that same timeframe, things become even more interesting. Here’s a list of every hitter, in no particular order, who, in any given season, minimum 150 PAs, achieved (1) more walks than strikeouts, (2) an ISO better than .130, and (3) a hard-hit rate better than 33 percent.
