This post is primarily a list. It includes the rankings of the 109 pitchers who, as of the Memorial Day weekend, were on a pace to qualify for the ERA title.
The pitchers are divided into four relatively equal groups, or quartiles, in each of two statistics. Those measures are opponents' batting average (Hittability, or Hit) and strikeout:walk ratio (Strikeability, or Strike). The pitchers are assigned a number from 1 (top quartile) to 4 (bottom quartile). Those numbers are added for the total rating.
Thus, the best overall rating is 2 (1 in Hit plus 1 in Strike equals 2), and the worst is 8 (4+4=8).
The lists follow.

If you look closely at individual pitchers on the list, you can get some idea why some of them are doing well this season or why they aren't.
For example, look at C.C. Sabathia on the list of average pitchers rated 5. Why is he just an average pitcher, when he once was one of the majors' best. It's right there in his rankings. He's still difficult to hit, still in the first quartile. But he's in the 4 (bottom) group in Strikeability. That can mean he's having control problems, but it also could indicate that he's no longer able to put batters away by striking them out.
A note on Jeremy Guthrie: He ranked this badly even before giving up 11 runs in a start against the Yankees.
Also, I was listening on Sirius XM radio to a Twins game started by Kyle Gibson. During the pregame show, Minnesota's announcers were going on about his ERA and the wins he'd provided. I was thinking, without being able to look at my rankings, that he was pretty low in the Hittability/Strikeability combo. You'll see him on the 7 list. That portends struggles for him during the remainder of the season. Struggles the team's broadcasters never saw coming.
I'll have another post about what the collective individual rankings might mean in the pennant races. And this weekend, I intend to come up with similar rankings for batters, and what those might mean for them and their team.

Pitchers you should pick up, others you should avoid
Every year on the Memorial Day weekend, I study which pitchers are likely to improve their results based on two metrics that show how well they have been pitching. At the same time, I come up with a list of pitchers whose performance is likely to fall off during the final two-thirds of the season.
Some of the pithcers on the way up are pretty obvious. Clayton Kershaw and Corey Kluber weren't winning early. But they are Cy Young Award winners. And the metrics I use -- opponents' batting average, or Hittability, and strikeout:walk ratio, or Strikeability -- showed that both were pitching well during April and May.
In the study, I included the 109 pitchers who at that point were on a pace to qualify for the ERA title (1 inning per team game). I compared their Hittability and Strikeability ratings with their standing in strikeouts and wins. Pitchers ranking high in combined Hittability and Strikeability but low in the counting stats are likely to be rewarded with better results going forward.
Others on the good list are Jimmy Nelson, Wei-Yin Chen, Francisco Liriano, Aaron Sanchez, Chase Anderson and Michael Wacha.
If any of those pitchers are a product of a small sample size or luck, rather than talent, I'd suggest Nelson, Anderson and possibly Sanchez. The others all have a track record.
There are just two pitchers I would expect to fall this season. Usually, there are seven or eight pitchers, sometimes even more on the bad list. This year's players due for a fall are Mark Buehrle and Mike Fiers. Buehrle was easy to see coming. In recent years, he has started fast and finished poorly. I remember telling someone it was OK to draft him, but he should be traded by midseason or the first sign that he was faltering.
In my rankings, I divide players into four groups as equal as possible, based on where they stand in each category. Buehrle began the year as one of the majors' biggest winners, even though he ranked in the bottom quarter in both Hittability and Strikeability. That made him not only an obvious candidate to fade, but also one of nine pitchers who should be replaced in the rotation as soon as someone better could be found.
There are seven pitchers in the top one-fourth in both Hittability and Strikeability. They are also good bets for success between now and October: Jason Hammel, Max Scherzer (another Cy Young Award winner), Matt Harvey, Johnny Cueto, Jake Odorizzi, Felix Hernandez (Cy!) and Zack Greinke. The biggest surprises on that list are Hammel and Odorizzi, who is one of the reasons why the Rays still are contending in the American League East.
They are players you should seek to acquire in your fantasy leagues, if you don't already have them.
Pitchers to avoid or to dump, in addition to Buehrle, are Jeremy Hellickson, Alex Wood, Tim Hudson, Kyle Kendrick, Jordan Lyles, Jeremy Guthrie, Chris Tillman and Kyle Lobstein.
Hellickson has been at the top of the Hittability and Strikeability lists in years past. I'd suggest that he and Tillman might have previously undisclosed injuries. Hudson, Guthrie and Buehrle may simply be at the end of the line.
I'll have more posts on my Hittability/Strikeability ratings, and how they can be used to predict future performance.
