Moore’s New Weapon | The Process Report

Moore’s New Weapon

Matt Moore’s last outing was statistically uneventful. He did not complete six innings, permitted nine baserunners, a home run, and fought his fastball command throughout most of the outing. What  did stand out was his unveiling of a new pitch.

Harry Pavlidis of BrooksBaseball and BaseballProspectus wrote about Matt Moore using a cutter. This was the first instance of Moore using a cutter while pitching for the Rays. Moore broke out the cutter to kick off his third full season, just as David Price did back in 2011. Price has predominately used his cutter to righties, using it 521 times against them while just 66 times to lefties. In both cases, Price prefers to work the outer corner (the back door) with his cutter rather than come inside with it.

For Moore, the plan appears to be slightly different as most of the cutters he threw in his last start were knocking on the front door and coming in and/or down to righties.


Given that it was the first time Moore brought the pitch with him into a regular season game, the inconsistent location of the pitch is understandable. Additionally, Moore fought his command most of the start so that would also show up in how he threw all of his pitches and not just his fastball. Jake McGee blamed his work on his cutter during spring training last season as one reason why his fastball command and early April results were so poor.

Moore’s career splits are rather small as there is just a 15-point difference in his wOBA to righties and lefties and his traditional slash line stats are within points of one another. He is more prone to home runs when facing righties, which accentuates the importance of locating his new toy. It is fine to miss on a front door cutter because it can back the batter off the plate to set up the next pitch low and away. Consider this 5th-inning sequence to Jonathon Diaz


  1. 1st pitch: fastball
  2. 2nd pitch: fastball
  3. 3rd pitch: changeup
  4. 4th pitch: cutter
  5. 5th pitch: changeup – ground ball out

A bad miss with a backdoor cutter, more often than not, results in four bases. As Moore continues working on this pitch, there will likely be some speed bumps. In the mean time, it gives hitters another pitch to think about while potentially allowing him to work deeper into games by inducing a few groundball outs rather than going for strikeouts.


  1. […] Throughout the spring, I tracked new pitches that were reported by the media. One flew under the radar because it went unreported until it showed up in the pitch f/x data last week. Matt Moore is now throwing a cutter. […]

    If you watch the replay of this pitch, it wasn’t supposed to be a backdoor cutter. He was trying to go in and just left it up (see attached screenshot – Molina set up inside). Regardless, good analysis and I’m interested to see if this pitch can be a positive for Moore this season.

      Right – his intention on his cutters appears to be to come in rather than try to go backdoor with it. The backdoor cutter requires strong command of the pitch so you don’t let it bleed back across the plate when it misses, and Moore does not have that (right now).
