Alvarez's across body motion is similar to Jake Arrieta's while he was in Baltimore. Upon his arrival in Chicago, Arrieta began to exaggerate his cross body motion which led to a Cy Young season. If Alvarez can move closer to the 1st base side of the rubber and exaggerate his cross body throwing action it could create more deception and possibly a greater break on his slider. This would also open the door for an effective two seam fastball or an increased use of a changeup that would break away from the left handed hitter and break into the right handed hitter's fists.
Henderson Alvarez could see a career revival with the proper tutelage and in the proper situation that would allow him to be most effective. The American League East, though loaded with talented power hitters, is a good match because of his break from the norm of high velocity pitchers in the division. Alvarez could become a quality bottom of the rotation starter for a cheap price this offseason.
