Can Josh Johnson Rebound For Blue Jays

Josh Johnson’s first (and possibly only) season as a Toronto Blue Jay has been an unmitigated disaster. Between injuries and ineffectiveness, Johnson has been worse than what many imagined was the worst-case scenario thus far.
Or has he?
While it is indisputable that Johnson’s results have been anything less than horrendous, he’s currently sporting a 6.08 ERA to go along with his 1-7 record, what is disputable is why his results have been so poor.
Many reasons have been thrown out to give reason to Johnson’s grievous efforts, from his status as an “NL Pitcher”, to his penchant for ‘nibbling’ around the strike zone, and his very real fastball decline.
While contemplating Johnson’s season, and what exactly the Blue Jays should do with him for 2014 I ended up on his FanGraphs page. I started comparing Johnson’s career numbers to his numbers in 2013, and I was surprised what I found.Season
If you’re unfamiliar with the above stats, check out the FanGraphs Glossary here.
What the above chart tells us isn’t all that surprising for those that have seen both past and present Josh Johnson. He is throwing less pitches in the strike zone (8% less which is kind of a lot). By virtue of throwing more pitches out of the zone, Johnson is getting more swings at non-strikes, but his also giving up more contact on pitches outside the zone.
Aside from that, Johnson’s swinging strike rate, in-zone swings, and in zone contact are virtually identical. The pitches and contact outside of the zone are odd, somewhat concerning, but certainly don’t explain the ineffectiveness.
Off to chart number 2!
Josh Johnson has been a very similar pitcher this season to what he has been throughout his career. In fact xFIP has Johson has pitching slightly above his career average! If you didn’t spot it on your first time over, check out the above chart again…do you see the one anomaly that is causing Josh Johnson’s results to deviate from his peripherals?
DING DING DING
If you spotted that Johnson is giving up home runs on 18.7% of his fly balls, you’re correct!
In case you were wondering, which after seeing that statistic I certainly was, HR/FB rate is minimally under the control of the pitcher.
"While pitchers can control (to a certain extent) the type of batted balls hit against them, there is less skill involved when considering whether a long fly ball is hit into the seats or to the warning track…. extreme home run rates in either direction are likely unsustainable."
Alright, so Josh Johnson has an 18.7% HR/FB rate, which is a full 10% higher than his career average, maybe he was playing with fire his whole career and he’s now regressing to the norm right?
Wrong! The MLB average HR/FB rate is generally around 9.5%, FanGraphs tells us that anything above 13% is considered “awful”. So Josh Johnson’s 18.7% rate? Due for a nice big ol’ serving of regression!
You may now be wondering what if Josh Johnson’s HR/FB rate regresses, what can we expect from him? For that we can look at xFIP, a stat that takes FIP and “normalizes” the home run component, by replacing the pitcher’s HR/FB ratio with one of 10.5% (slightly below average). As mentioned earlier Josh Johnson’s xFIP for the year is 3.54.
Josh Johnson in his career has actually outperformed his xFIP in terms of ERA, whether that was due to defense or just plain luck is to be seen, but if Johnson can normalize that HR/FB ratio would it be some much to expect an ERA under 4.00 for the rest of the season?
I think not.
I’m going to go out on a limb here (but maybe not if you believe in the above statistics as I do) that Josh Johnson will be the Blue Jays best pitcher over the next two months. He’s going to pitch well enough that we Jays fans will feel silly for ever having doubted the fact we would extend him a qualifying offer, and will be extolling his effectiveness at this time next year when the Jays are in the middle of a pennant race.
That is unless he doesn’t, and in that case you can all make fun of me in the comments section or on Twitter.
