Jose Quintana’s Steady Improvement

It’s been an improbable ride for Jose Quintana. After signing with the White Sox as a minor-league free-agent last season, Quintana held his own in 22 starts in the majors. While nothing about his game stood out, and the advanced stats were bearish on his ability to repeat, it was nonetheless a win for the club. Quintana entered 2013 as the team’s fourth starter, a position he was capable of filling given his skill set. But a the midway point, Quintana has emerged as the team’s second-best starter. While that may not be impressive given the club’s injuries, it’s clear that Quintana has taken a significant step forward.

Quintana succeeded in 2012 with a solid, yet unspectacular, skill set. He wasn’t able to strikeout many hitters, instead relying on solid control and a steady diet of ground balls. That approach can be effective, but is generally reserved for back-of-the-rotation starters. That was Quintana’s future unless he magically started striking out hitters.

That’s exactly what happened this season. Quintana’s strikeout rate his jumped from 14.3% to 19% due to an improved fastball. The biggest reason for Quintana’s effectiveness with his heater is a rise in velocity. This was actually somewhat evident last season, as his average fastball velocity increased every month, ending up at 91.42 mph in September, according to Quintana didn’t stop there. The pitch has been even faster this year, with an average velocity of 92.25 mph.

The increased velocity has helped Quintana garner more strikeouts. His whiff rate with the four-seamer has jumped from 6.75% to 10.57%. That’s hardly an elite rate, but it’s a significant improvement. Looking at his pitch usage numbers, it’s clear Quintana is aware of his increased effectiveness with his fastball. He’s started using his four-seam fastball more often in two-strike counts.

Year FB All Counts FB Two Strikes
LHH 2012 46% 34%
LHH 2013 47% 47%
RHH 2012 49% 40%
RHH 2013 44% 49%

The biggest change can be seen against left-handed hitters. Quintana shied away from using the pitch with two-strikes against lefties in 2012, with his usage falling to 34%. That’s jumped 13% in 2013. Quintana’s overall fastball usage has dropped against righties, but not in two-strike situations. His usage has jumped nine percent in those situations. Hitters performed well against Quintana’s fastball in 2012, hitting .283, with a .474 slugging percentage. Those numbers have dropped to just .205 and .351 respectively. Quintan’s PITCH f/x pitch type value with his four-seamer is 10.7, making it the ninth best fastball this season. In 2012, the pitch rated 41st among pitchers who tossed at least 100 innings.

In the grand scheme of things, Quintana’s outlook has only improved slightly. Instead of being a back-of-the-rotation guy, Quintana has shown enough ability to probably survive as a three-starter. On a White Sox team lacking young pitching talent, Quintana has emerged as a viable future contributor. Given that he isn’t set to be a free-agent until 2019, Quintana can be a mainstay in the rotation as the team rebuilds, or can be used as a controllable asset in a trade. Considering Quintana wasn’t worth a major-league deal last offseason, his rise is nothing short of meteoric. His overall upside may not be significant, but that shouldn’t take away from what he’s already been able to accomplish.

    Chris, thanks for this. Keep watching him but have yet to pick him up. In a 12-team 5×5 redraft, can you please rank Hudson, Griffin, Erasmo and Quintana ROS? Thanks so much.

    Setting up those fastballs with more curveballs and changeups and fewer sliders. Also, can you shine my shoes please.

    Not sure how the White Sox lack young pitching talent. Their rotation next season could likely consist of Sale, Santiago, Quintana, top prospect Erik Johnson, and Danks. They lack just about everything other than young pitching talent.

    Looking at the White Sox’ system reveals deep pitching stables.

    SP- Sale, Quintana, Santiago, E. Johnson, Danks. Maybe even Leesman and Axlerod as lower ceiling, #5 types

    RP- Reed, Jones

    Looks like they have a kid Webb in the high minors just blowing people away with a polished 100 mph

    Probably the envy of 29 other teams. At least arguably.

    Every organization has young pitching talent. I think he meant the Sox lack “good” young pitching talent.

    • Yinka Double Dare says:

      3 out of the 5 guys in their rotation now are 25 or under, and all of them are at worst mid-rotation kind of guys. One of them is undeniably a #1. And hell, John Danks is still only 28.

      Young pitching talent is one thing. Young, effective, major league talent is another. This is why I don’t think the White Sox rebuild will last as long as some people seem to believe. They can pitch.

    In that context, “good talent” is very redundant.

    The White Sox pitching staff ranks 3rd in team pitching WAR this year. It is a young staff that is built on Chris Sale, Hector Santiago, Jose Quintana, and has even had contributions from Dylan Axelrod. John Danks is only 28 and Peavy is obviously a great piece of the rotation, though he’s now missed significant time. Jesse Crain has contributed to the WAR value, but not much. Addison Reed in the pen has done very well and Nate Jones has reclaimed this season as well (though his FIP has always been good). They have well-regarded starting and relieving prospects.

    Author just made a flip comment, so it’s not a huge deal. It’s still extremely inaccurate, though.
