Jose Quintana’s season is a little difficult to figure out. In three of his first four starts, he allowed 17 runs combined; in that fourth appearance, he pitched six shutout innings. Over four of his past five starts, meanwhile, he’s conceded one run total; he allowed six runs in the other.
Is he improving as the season goes on? He struck out 16 batters against 11 walks in 19.2 innings in those first four starts and struck out 29 hitters and walked 14 in 28.2 innings over the past five outings. His ERA is much lower in the latter of those two periods, but his FIP hasn’t moved a great deal, going from 5.15 to 4.37. These samples are small enough that it would be fair to conclude little to nothing had changed at all, but given his excellent track record, there has to be something to Quintana’s struggles.
A year ago at this time, there were some questions about Quintana’s trade value for the White Sox after the left-hander started slowly. Over his first 11 outings last season, Quintana had authored a 5.60 ERA and 4.40 FIP. Most of Quintana’s issues in terms of ERA stemmed from an increase in homers and a poor left-on-base percentage. After investigating Quintana’s numbers, I felt that most of Quintana’s issues were probably luck-based and unlikely to continue. Brushing off those concerns looks pretty good in hindsight, as Quintana put up a 3.30 FIP and 3.40 ERA and allowed just under one homer per nine innings the rest of the way, eventually helping a Cubs teams desperate for quality starter innings. This season, Quintana’s issues aren’t as easy to brush off.
While Quintana’s current FIP might resemble last year’s figure at roughly the same point in the season, his 4.68 FIP is nearly 20% worse than league average after accounting for the change in league and park. Additionally, there isn’t a gap in contact quality that suggests perhaps Quintana is just getting unlucky. So far, Quintana is giving up home runs because he has deserved to give up home runs. He’s striking out fewer batters than he did a year ago while his walks have gone way up. These are all bad things.
If there’s any cause for hope, it is twofold. One, Quintana has shown some flashes of being the very good pitcher he was before the season started, putting up four starts of at least six innings and zero or one run with at least five strikeouts. The second reason for optimism is that Quintana is still tinkering.
