Rick Porcello: What’s Gone Wrong?
No one expected Rick Porcello to repeat his 2016 Cy Young season besides maybe his mom. And she probably had some doubts. Before the season started, I thought he was getting punished too much especially after some second half changes. So far, I have been wrong with Porcello maintaining his 2016 production with a 3-9 record and a 5.05 ERA. Here’s what has gone wrong.
Less Help
Last season, quite a bit of Porcello’s fantasy value came from his 22 Wins. While 22 Wins was out of the question this season, owners expected more than three. Porcellos has giving up an extra run per game and the Red Sox offense has dropped off.
Last season, they average scoring 5.4 R/G and this season that number has dropped to 4.7 R/G. With the league scoring up, the Red Sox have gone the other direction.
BABIP Jump
Porcello posted a .269 BABIP last season which could be explained by his high flyball rate leading to easy outs. This season, his flyball rate has increased from 38% to 41% and his BABIP has jumped to .366 (2nd highest value among qualified starters).
Part of the blame can be place on the defense behind as the team BABIP has jumped 20 points from .293 to .313. Additionally, the team’s UZR/150 has dropped from 4.3/150 to 2.7/150. The defense can take some of the blame, but not all of it. Which is obvious with the next factor.
Giving up Home Runs
When Porcello transitioned to be a flyball pitcher in 2015, he posted a career high 1.3 HR/9. In 2016, he was able to suppress home runs and keep his HR/9 under 1.00. That is not the case this season with a possible new career high 1.6 HR/9.
A high HR/9 rate is somewhat expected as he gives up more and more flyballs. Also His 2016 HR/FB isn’t completely out of place at 13% with his career rate of 12%. The problem is that he is not getting any of BABIP advantage from non-home runs flyballs turning into easy outs.
All of his projections and ERA estimators place his ERA near 4.00. With scoring up again, a 4.00 ERA is acceptable with overall league average starter ERA at 4.51. I think owners are having a tough time coming to grips with the new scoring environment.
Striking Out Fewer Batters …
Porcello is pulling the ol’ my strikeouts look like they are improving but aren’t because we are still using K/9.
Here are Porcello’s K/9 and K% over the past two seasons.
Season: 2016, 2017
K%: 21.2%, 20.5%
K/9: 7.6 K/9. 8.3 K/9
With all the extra hits Porcello is giving up, he is getting to see more hitters every inning so his strikeout rates looks to be going up but isn’t.
… And Walking a Few More
Historically, Porcello has been stingy with the walks (5.3% career mark) and this season he is at 4.3% which is a small increase from 3.6% last season.
Bring All It Together
Everything is working against Porcello at this moment driving his price down. Finding an area for positive regression is tough to find. Are the Red Sox going to hit and play defense better? Is he going to quit giving up so many hard-hit flyballs (home runs)? Can he strike out more batters? The only item I feel good about is some BABIP regression and hope for a near 4.00 ERA for the rest of the season.

I learned nothing from this.

Other than the fact that Porcello has been pretty bad this year, returning to his career norm of just average to not good.
Drop him for Homer Bailey?
MLBs Jim Kaat claims hes pushing off,that and the factors listed above
He seem to throw more freely.last night.
His ball had much better movement.
Porcello still probably carries enough name value that even if one tried to buy very low on him, the other person would still demand something of decent value. However, I don’t get the impression that the author suggests buying Porcello at all given all of the negative evidence. Looking at the Red Sox schedule for the rest of the season, there aren’t even many streaming opportunities that the current version of Porcello should be used. Sounds like there is not much of a reason to consider Porcello at all this year unless one likes to gamble on miracle turnarounds.
All of this and we don’t even talk about him giving up a career high (and MLB high) 43.2% Hard Contact. Not understanding the why is outside of my knowledge base. Could just be changes in pitch locations.
“With all the extra hits Porcello is giving up, he is getting to see more hitters every inning so his strikeout rates looks to be going up but isn’t.”
Is he claiming that Porcello is giving him up more hits and therefore seeing more batters and *that’s* why he’s striking out more batters per nine innings? If so, that’s insane–no matter how many batters you face, the total number of strikeout opportunities (i.e., outs) is unchanged per nine.
Jim Bouton and Gene Brabender had exactly this argument in Ball Four.
So, I don’t like to be a troll etc… but looking at Porcello’s career, 2016 looks like the outlier. He not a horrible pitcher but he is not the pitcher from last year. He has never been that pitcher. He is more than likely only ever going to be the guy he was before 2016. 2017 seems a little on the bad side but by the end of 2017 it’ll even out and he’ll be back to his career norms. He is the data point that breaks the equation for FIP and other metrics and he is worth a a lot to a baseball team but he’ll never be that great pitcher it seems like his number say that he should be.
