For the next few weeks, the RotoGraphs staff will devote an entire week to each defensive position, including spotlights on particular players as well as trends throughout the 2015 season. This week, we’re highlighting shortstops.

I don’t claim to be a Tableau (or data visualization) whiz by any means, but I thought it would be cool to visually represent the shortstop landscape in 2015 — with some analysis sprinkled in.

Steamer and ZiPS represent premier player projection systems; FanGraphs’ Depth Charts combines the two, and the writing staff allocate playing time accordingly. The playing time part is less important relative to the combined projections, as aggregated projections tend to perform better than standalones.

I compared projected wOBA (weighted on-base average) from the preseason to actual wOBA (1) by team and (2) by player within team. Unlike WAR, wOBA is a rate metric, so it does not need to be scaled according to playing time.

You’ve read the title. Hold that thought.

The Toronto Blue Jays acquired second baseman Devon Travis from the Detroit Tigers last offseason. Having never played above Double-A prior to 2015, the Jays thrust Travis into major league action in a trial by fire. He held his own and then some, hitting a robust .304/.361/.498 with eight home runs and three stolen bases in only 238 plate appearances.

Travis may have experienced some good luck, benefiting from a .347 batting average on balls in play (BABIP) as well as a 16-percent rate of home runs per fly ball (HR/FB) — an impressive rate for a 5-foot-9, 195-pound 24-year-old. The 50-percent ground ball rate (GB%) and somewhat lowly 27.8-percent hard-hit rate (Hard%) don’t help his case in regard to the latter, either.

So Travis’ .194 isolated power (ISO) may not hold up under duress of the 2016 season. But he did post decent ISOs in the minors — .210 at High-A in 2013, .161 at Double-A in 2014 — and although the quality of competition pales in comparison to the real thing, it wouldn’t be unheard of for Travis to develop a modest power stroke. Kid’s something of a doubles machine, which would be a boon to any stat line.

For the next few weeks, the RotoGraphs staff will devote an entire week to each defensive position, including spotlights on particular players as well as trends throughout the 2015 season. This week, we’re highlighting first basemen.

I don’t claim to be a Tableau (or data visualization) whiz by any means, but I thought it would be cool to visually represent the first base landscape in 2015 — with some analysis sprinkled in.

Steamer and ZiPS represent premier player projection systems; FanGraphs’ Depth Charts combines the two, and the writing staff allocate playing time accordingly. The playing time part is less important relative to the combined projections, as aggregated projections tend to perform better than standalones.

Previously, I compared actual WAR (wins above replacement) to projected WAR. This is not entirely helpful in a fantasy context, however, given WAR is a catch-all component metric for offense and defense. Defense doesn’t do us a whole lot of good for fantasy purposes.

Thus, I figured out a way to compare projected wOBA (weighted on-base average) from the preseason to actual wOBA (1) by team and (2) by player within team. Unlike WAR, wOBA is a rate metric, so it does not need to be scaled according to playing time.

First: the difference between a team’s wOBA generated by first basemen and their projected wOBA. Blue represents the highest expected wOBA; yellow represents lowest expected wOBA. The size of the bar above (below) the line represents actual wOBA above (below) expectations.

The best of, worst of awards continue this week along with a spotlight on fantasy baseball’s catcher landscape in 2015. Last week, I awarded the 2015 Sigh Young — fantasy baseball’s biggest pitching bust — to Jeff Samardzija, who miserably underperformed expectations en route to a pretty awful season.

The 2015 Roto Overhyped Pitcher award is a bit different and probably more subjective. Rather than simply be bad, a pitcher must have also been over-hyped. Too much hype typically occurs for two reasons, neither of which are mutually exclusive:

1. The pitcher was once a top prospect
2. The pitcher broke out, or turned the corner, the previous season

For the next few weeks, the RotoGraphs staff will devote entire weeks to each defensive position, including spotlights on particular players as well as trends throughout the 2015 season. This week, we’re highlighting catchers.

I don’t claim to be a Tableau (or data visualization) whiz by any means, but I thought it would be cool to visually represent the landscape of all catchers in 2015 — with some analysis sprinkled in.

Steamer and ZiPS represent premier player projection systems; FanGraphs’ Depth Charts combines the two, and the writing staff allocate playing time accordingly. The playing time part is less important relative to the combined projections, as aggregated projections tend to perform better than standalones.

I compared projected WAR (wins above replacement) from the preseason to actual WAR (1) by team and (2) by player within team. I scaled the expected WAR by playing time to correct for injuries, trades, call-ups, etc. Ideally, it’ll be a little more accurate and, perhaps, fairer than comparing actual results to projections straight-up.

Back in April, the RotoGraphs staff made some picks for the season. Vague, I know, but I assume you understand what kind of picks I’m talking about.

And because I like competitions, I’m going to turn this into one. As the moderator of these picks, I’m judging it by my own silly subjectivity.

The rules are simple:

• One point for the winner of each category
• Most points wins
• No touching of the hair or face

That’s it! Now let’s do this!!!

It’s best of and worst of week at RotoGraphs. I’m here with 2015’s worst starting pitchers.

There’s a lot of ways to approach this. A lot of pitchers’ values are conditional upon their circumstances, so I’ve tried to keep this in mind when creating this list. When it comes down to it, though, this is all just one man’s opinion.

Fantasy Pros calculated the aggregate average draft position (ADP) using several premier fantasy baseball websites, so that’s the value upon which I’ve based my decisions.

But first, let us acknowledge 2015’s All-Injury Sigh Young Squad:

The 2015 season humbled me. In 2014, I reached the playoffs in all four of my leagues and won two of them. I cleaned up at each draft and I cleaned up on the waiver wire. I felt unstoppable. I felt like I had it all figured out.

Then 2015 happened. I botched my first (and most important) draft (“LOWV,” henceforth). Then I botched then next one. Then I botched the two snake drafts, as I always do. I botched the Birchwood Brothers‘ Birchwood Derby midseason draft as well. Botched. Botchy botch botched.

Right. So I learned some things. You’re never too old, nor too wise, to learn. Conveniently, I’m neither old nor wise, so I still have plenty of learning to do. And when Major League Baseball turns in a season as unpredictable as this one, well, everyone learns a thing or two.
