Hector Santiago reads FanGraphs and throws a screwball. The former puts the Chicago White Sox southpaw in the minority among big-league players. The latter makes him quite unique.
A handful of present-day hurlers pull the occasional screwball out of their back pocket, but none feature the pitch. Santiago doesn’t either, but if he wins a job in the starting rotation next season — a distinct possibility — there is a good chance it will become his signature offering.
The 24-year-old New Jersey native worked out of the bullpen in 42 of his 46 appearances this year, which impacted his repertoire. As he explained during a visit to Fenway Park, “It‘s tough to come in for one inning and throw screwballs. As a starter, you have more opportunities to throw it.”
Santiago wants to start, and knows what he needs to do to earn that role. Along with reintroducing more screwballs to his mix, he said he needs to “work on a two-seam fastball, something that is going to sink down out of the zone, so I can get more ground balls.” His GB-rate was 38.2, which he’s well aware of. He hasn’t yet established himself as a starter, but he’s already a stat-savvy screwball artist.

Santiago on his repertoire and approach: “I basically try to go after hitters and hit my spots. I’m a guy who is mostly on the inner half to right-handers and away to lefties. I try to get it down and in to righties and down and away to lefties, and let them basically get themselves out. How my ball moves is a big part of how I pitch.
“I watch at a lot of video, especially when I’m getting hit, or when I’m missing and think some of the pitches are balls or strikes. I go back and check the k-zone to see how the pitches were moving and where they finished up. That’s especially true on my off-speed. I feel that I can see pretty well on my fastball — where it’s going to go and where it lands — but with my off-speed, sometimes I think it’s a good pitch, just off the plate, and when I go back in, it’s more on the plate than I expected. When I get hurt is when I‘m missing over the middle of the plate. That‘s when they‘ll run into it.
“When I came into pro ball, I was a one-pitch guy. They helped me develop a changeup, and I started to be able to spin a slider in there. I can work in other pitches now. I can throw my changeup for a strike, or out of the zone, I have a cutter now. I can throw my slider early in the count or behind in the count, although it’s still a work in progress. And then there’s my screwball.” Read the rest of this entry »
