Two-Pitch Starters Needing a Third Pitch

by
February 20, 2018

Every year Jason Collette puts together a list of pitchers who are adding a new pitch. Last year, over 50 different pitchers said they were adding/changing at least one of their pitches. Once the season was over, the pitchers who made the biggest gains from adding a new pitch weren’t on the list. As much as I personally enjoy helping with the list during the spring, it doesn’t help fantasy owners. Instead of focusing on the list, I’m going to work propose a different method for finding pitchers to target.

Once every season ends, I go examine where the fantasy industry missed on players. Two top-15 pitchers who made the list were Robbie Ray and Luis Severino. In both cases, they began to effectively utilize a third pitch. For Severino, it was a changeup which generated a 13% SwStr% and his K/9 jumped from 8.4 to 10.7 and his ERA dropped from 5.83 to 2.98.

For Ray, it was a curveball which did even better with an 18% SwStr%. He didn’t see as much of an improvement with his strikeouts inching up from 11.3 K/9 to 12.1 K/9 but his ERA dropped from 4.90 to 2.89. Both pitchers toyed around with the pitch previously but never fully bought into it.

Both pitchers were being taken at the end of drafts or not at all. Each was the breakout owners strive to roster. I’ve been thinking of a possible solution.

Instead of waiting for reports on a pitcher adding a pitch, I’ll find the pitchers who are most likely to benefit from a third breaking pitch. They are already getting by with just a fastball and one breaking pitch but a second breaker may put them over the top.

With these pitchers, I’m going to try to put on my best scouting hat and see if they add a decent one during spring training. Scouting pitchers in Arizona is an advantage with three pitch tracking systems installed to see if they are using a new pitch. Otherwise, I’m going to have to watch some games and see what they’re utilizing. If I find anything out, I will let our readers know but I may not be able to watch every pitcher so I’m making a target list available for owners if they want to do their own investigation.

To find the targets, I grouped the pitcher’s fastballs together and then added the percentage use of their most used breaking ball. The pitcher with the highest total from just two pitches is Dinelson Lamet at 56% fastball and 40% slider. He toyed around with a change but hasn’t bought into a third pitch he trusts.

I’m not sure if this process will yield any positive results. Just going through the new-pitch mentions didn’t work.

Here are the pitchers (min 80 IP) who utilized two pitches 85% or more of the time. For fastballs, I grouped all the pitches labeled two-seam, four-seam, and sinker together.

Of these pitchers, I going to concentrate my efforts on the younger pitchers. I’m not going to hope the old dogs (Colon, Hill, Lynn) will learn new tricks.

Of the pitchers with the most to gain, here some information on the what the third pitch could be.

Dinelson Lamet

The pitch to look for will be his changeup. Its peripherals were fine but the results were horrible (vs .419 wOBA). He started the season using it more (14% in May) but drop its usage each month until he didn’t throw it at all in September.

Changeup
2017
13% SwStr%, 46% GB%
Baseball America (BA): “… projects average…”
2016
MLB.com (MLB): 45 grade, “…in its nascent stages…”
BA: no third pitch

Antonio Senzatela

Reading through his previous scouting reports, he seems to have just developed his slider to go with his fastball. His change just seems to be behind but its peripheral stats mimic his slider.

Changeup
2017
12% SwStr%, 33% GB%
BA: ” …showed flashes of being an average weapon…”
2016
MLB: 50 grade, “…second-best offering is a changeup that ranges from 45-55…”
BA: “… His straight, downward tumbling changeup has a chance to be plus.”

Luis Perdomo

Perdomo thrives by keeping the ball down in the zone with his sinker and curve. His groundball rate is elite (62%) but his lackluster strikeout rate (6.5 K/9) is keeping him from being among the league’s best. Developing an average change/splitfinger could put him over the edge. Right now it grades out to below average.

Change (label a splitter at times)
2017
8% SwStr%, 61% GB%
2016
12.4% SwStr%, 52% GB%
BA: “… firm changeup…”

Chris Archer

Archer always seems to be developing his change and keep usage around 10%. Besides its low Zone% (35%), he should just keep throwing the pitch. It performs better than his fastball. For him it’s not developing the pitch, it’s using it.

Change
2017
14% SwStr%, 48% GB%
2016
13% SwStr%, 65% GB%
2015
15% SwStr%, 60% GB%

This is a fun exercise and a great starting point list. I especially appreciate the sourced notes & stats on the potential third offspeed pitch – thanks!
