Arizona Diamondbacks: Giving players their final letter grades

Arizona Diamondbacks: A breakout star

Ketel Marte: A+

This season was Marte’s coming out party.  He absolutely crushed the ball all season long, hitting .389 and slugging .592.  He had 32 home runs and 92 RBI’s, by far and away career highs.  He also made the first of hopefully many All-Star games to come.  (Note: While Marte did play in the infield I have him listed here as the D-backs official roster has him listed as an outfielder.)

Jarrod Dyson: B-

Dyson had a decent season, hitting .230, but it was one of the lowest batting averages of his career.  He was pushed into more service with both David Peralta and Steven Souza Jr. on the IL.  He was a speedster and stole 30 bases, but beyond that, he was simply average.

Adam Jones: B-

Jones gets this grade for filling the role the D-backs had in mind for him when joining the team.  He provided veteran leadership in the clubhouse and held his own at the plate.  He struggled at the plate compared to previous seasons, having the worst batting average of his career since his second year in the league.

Tim Locastro: C

Locastro appeared mainly off the bench and to give guys days off in his third season in the majors.  He played in 91 games, but only had 250 plate appearances although he hit a respectable .250.

David Peralta: C+

Peralta failed to meet some of the lofty expectations we had for him after his career year last season.  He did miss some time after being injured towards the end of the season so that really can’t be held against him too much, but he just wasn’t himself this year.
