Arizona Diamondbacks: Giving players their final letter grades

The 2019 season was filled with ups and downs for the Arizona Diamondbacks, but there were plenty of individuals who turned in solid performances for the year.

The 2019 version of the Arizona Diamondbacks was at times incredibly frustrating and incredibly exciting to watch.  It seemed like every time they were close to something special after a long winning streak, they were brought back to earth by a losing streak.

Now while we did not give out letter grades for the half-way point of the season, we are going to go over everyone’s performance.  There will be players who weren’t with the team for the entire season, who were traded away or acquired and as long as they played a significant role for the team, they will be included here.

The rating will follow your typical A, B, C, D, F grading system and several things will be taken into consideration.  Individual statistics compared to past seasons, filling their specific role on the team and how well each player contributed to the team as a whole.

As per usual these letter grades are up for debate, they are merely my opinion.  Make sure you comment below and let me know what you think!

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.

Arizona Diamondbacks: some inconsistent starting pitching

Zack Greinke: A-

Greinke had a phenomenal season pitching for the D-Backs.  It just so happened they needed to get out of his contract and were able to pull off a trade to the Astros.  He went 10-4 with a 2.90 ERA in 23 starts.  I’m just sad to see him go.

Robbie Ray: B

Ray gets a B because I still feel like he is underperforming.  He shows flashes of brilliance with the strikeouts but also gets in trouble walking batters.  He went 12-8 with a 4.34 ERA with 235 strikeouts compared to 84 walks.  He could be so much better.

Merrill Kelly: C+

Kelly gets this grade because he was a little bit better than okay. Keep in mind he was a rookie this past season.  He struggled giving up the long ball this year and went 13-14 in 32 starts with a 4.42 ERA.  His 14 losses led all of baseball.

Taylor Clarke: C

Clarke, another rookie pitcher like Kelly also had an okay season.  He went 5-5 with a 5.31 ERA in 15 starts.  He also struggled giving up the long ball, giving up 23 of them and walking 30 batters.

Alex Young: B-

Young was another rookie pitcher who made 15 starts.  He went 7-5 with a 3.56 ERA and was able to keep the walks and home runs allowed to a minimum.

Luke Weaver: B+

Weaver made 12 starts, going 4-3 with a 2.94 ERA.  The third-year pitcher acquired from the St. Louis Cardinals showed great promise and will be a centerpiece of the rotation for the next few years.

Mike Leake: D

Leake flat out did not impress at all during his time with the team.  He went 3-3 in 10 starts with a 4.35 ERA.  It’s hard to justify having him in the lineup taking starts away from some of the young promising starters.

Zac Gallen: A

Gallen is the pitcher I am most excited about of this bunch.  He has the potential to be a great starter.  He didn’t make many starts after coming over from the Miami Marlins, but what he did do was impress.  He went 2-3 with a 2.89 ERA in 8 starts, striking out 53 and only allowing 5 home runs.

Arizona Diamondbacks: The bullpen was a mess

Archie Bradley: B-

Bradley came into the closer’s role late in the season and did okay.  He had a 3.52 ERA and was 18 for 21 in save opportunities.  The problem is he could be so much better.  That is too many blown saves for one closer especially with the fact he wasn’t the closer the whole season.

Greg Holland: C-

More from Call to the Pen

• Philadelphia Phillies, ready for a stretch run, bomb St. Louis Cardinals
• Philadelphia Phillies: The 4 players on the franchise’s Mount Rushmore
• Boston Red Sox fans should be upset over Mookie Betts’ comment
• Analyzing the Boston Red Sox trade for Dave Henderson and Spike Owen
• 2023 MLB postseason likely to have a strange look without Yankees, Red Sox, Cardinals

The Holland experiment was a failed one, much akin to the Leake one.  He had a 4.54 ERA and was 17 of 22 in save opportunities.  Combined with Bradley they went 35 for 43 in save chances.  That is an extra 8 games the team could have won.  That is why he was released in August by the Arizona Diamondbacks.

Yoan Lopez: B

Lopez was pretty good throughout the season.  He was 2-7 but carried a 3.41 ERA in 70 appearances.  He is a good young player who should develop nicely for the team.

Yoshihisa Hirano: C

Hirano struggled this season after pitching really well last season.  He carried a 4.75 ERA in 62 games.  Compare this to 2.44 ERA last season and you’ll understand the letter grade here.

Andrew Chafin: B

Chafin was a stalwart in the pen.  He went 2-2 with a 3.76 ERA and only 18 walks in 77 games.  He should continue this production moving forward.

Matt Andriese: C

Andriese went a palsy 5-5 with a horrible 4.71 ERA in 54 appearances.  Not exactly the kind of ERA you want from one of your relievers.

T.J. McFarland: C

McFarland also struggled with a 4.82 ERA in 51 games.  Again really struggled when it really mattered.

Kevin Ginkel: A

Ginkel, a rookie emerged as a star in the bullpen.  He only appeared in 25 games, but had a 1.48 ERA and ended with 2 saves throughout the year.  If he can cut down on his walks, he will be a major contributor at the end of games.

Stefan Crichton: B

Crichton, in his first action since 2017 went 1-0 with a 3.56 ERA in 28 games.  Given this was his first time back, I’d say that was pretty good.
