Hot Stove Scouting Report

Attacks the zone with two primary pitches—fastball and slider; has shown ability to throw consistent strikes with all pitches in the past (51.4% in 2013), but regressed in this regard in 2014 (47.7%); worked slowly between pitches and rarely seemed truly comfortable on the mound this year; still attempted to attack the strike zone but could not always execute; lacked attempts at challenging inside with pitches and was rarely successful when he tried to move the fastball to the inner third; needs to regain strike-throwing ability that should enable him to be more aggressive in all parts of the strike zone, as well as out of the strike zone.

Confident on the mound; carries himself with professionalism one would expect of a seven-year veteran; shows some frustration on the bump, mostly with himself, but controls aggravation well and regains composure quickly; displays quality makeup on field.

Slider is still a high-quality offering; calm, cool and collected on the mound; big, durable frame with good strength; track record of durability and chewing up quality innings; movement on fastball can be occasional strength but was not consistent in 2014.

Fastball velocity backed up in 2014 and was not the type of pitch that could consistently beat MLB hitters; changeup remains below average; command and control regressed and was a weakness in 2014; arm speed and ability to keep arm with rest of body throughout delivery must improve/return going forward.

Assuming minimal improvement in ability to command fastball, hitters can remain patient and wait for fringy fastball to come into prime hitting zone, or wait for a walk; have to lay off slider as the pitch represents his only reliable offering; hitters should attack changeup if identified and left up in the strike zone; pitches above mid-thigh can be lifted and driven with authority consistently due to lack of movement in 2014 sample.

Will pitch entire 2015 season at 30-years old; potential bargain on the free agent market; experienced somewhat mysterious drop in velocity in 2014 and if only temporary could result in a strong resurgence during the coming season; worthwhile gamble for any team looking for options at the back of the rotation, and may have even greater likelihood of success if tasked with navigating National League lineups; for relatively minimal cost and likely short-term contract, Masterson represents a low-risk, high-reward signing.
