Funky Jon Duplantier is Dbacks’ Ace pitching prospect

Reno Aces pitcher Jon Duplantier has funk in his arm.

“He’s just funky, no other way to put it,” Aces pitching coach Jeff Bajenaru said. “He has some nastiness to him and hitters don’t like it.”

The Arizona Diamondbacks top pitching prospect went three innings, surrendering one earned run on three hits and three strikeouts in the Aces’ 9-5  loss to the Fresno Grizzlies on Wednesday. He has a 1.04 ERA and 10 strikeouts with Reno this season.

Duplantier’s unconventional approach on the mound all starts with his long-arm, low three-quarter slot delivery. Once the right-hander winds up, he hides the ball behind his head before he delivers a strike to the plate, a routine he’s developed growing up in Katy, Texas.

“I’ve been throwing this way forever,” he said. “There’s pictures of me at 10 years old throwing the way I throw now. I didn’t realize it was all that weird until one of my teammates told me in college.”

Opposing batters can’t hide from his devastating four-pitch arsenal. He gets ahead of the count with a mid-90s two-seam fastball with plenty of sink that runs off the plate. In two-strike situations, he’ll showcase a hard-breaking slider to whiff right-handed hitters. Duplantier also has developed a mid-80s change up and effective curve to force ground balls.

His third strikeout on Wednesday night was an 85-mph slider that broke at the hands of Fresno third baseman Matt Reynolds.

“My off-speed stuff is huge,” he said. “Guys are throwing real hard so my slider can and breaking ball can take a load off my fastball and it can add to it. It’s all just a means of keeping the hitter off balance. … They have to honor one or both, and they complement each other really nice in the way they move.”

Duplantier, 24, who pitched with Double-A Jackson last season, made his big-league debut for the Diamondbacks on April 1. He posted a rare three-inning save with two strikeouts against the San Diego Padres.

“I had no idea I even got the save,” he said. “Now it’s one of the coolest moments of my life.”

Duplantier appeared in two games with the Dbacks before being optioned to Triple-A Reno on April 9. He’s returned to his  starting role with the Aces on a limited pitch count, throwing 97 total pitches in 8.2 innings pitched this season.

“The mentality is different between the two,” he said. “In the bullpen, it’s about getting the out at all costs and go to work. Starting, it’s a little bit more like a chess game. You have to go back to the at-bat before and the next (player) in the order. It’s a whole different ball game.”

Duplantier’s arm hasn’t only been seen on a diamond. He was a Houston high school quarterback for the Silver Lakes High School Spartans in 2012 and 2013. The two-sport star lettered in football and baseball during his junior and senior seasons.

Duplantier had a smooth touch with the football compared to his mechanical release on the mound. His 6-foot-3, 224-pound frame was a good size for the gridiron.

“I never threw footballs the way I throw a baseball,” he chuckled. “I had a tight, compact quick stroke with it. My arm was pretty stock when I launched (the ball) downfield. I could stand in there and take a hit, as well.”

Multiple injuries to his collarbone and wrist forced Duplantier to stick with one pair of cleats. A torn meniscus ended his senior football season with the Spartans and forced him to permanently stick to baseball.

“It was a tough decision, but I couldn’t take the beating of both (sports),” he said. “Football was fun, but baseball was my real passion. So I just stayed with that.”

The decision paid off handsomely. Arizona selected Duplantier in the third round of the 2016 MLB Draft after three college seasons with the Rice University Owls.

The right-hander has been and up-and-coming star since he was assigned to the Dbacks’ minor league system. Duplantier has not recorded a higher ERA than 2.69 over three seasons in High-A, Advanced-A and with Double-A Jackson. He was a Futures Game Selection during his time with the Visalia Rawhide in 2017.

Currently bouncing between the Dbacks and the Aces, Duplantier is getting used to the Biggest Little City.

“When you drive around here, the scenery catches your eye,” he said. “It’s beautiful out here. I’m not used to seeing so many mountains coming from Texas, let alone mountains with snow on them. … I’ve sent my parents a bunch of pictures.”

Duplantier may not be with the Aces for long. His strong arm and impressive stuff can help Arizona’s depleted bullpen or slot in the back-end of the team’s starting rotation.

He is the 69th ranked prospect by MLB Pipeline.

“He had a great spring training and opened a lot of eyes,” pitching coach Bajenaru said. “He works his butt of and is a competitor at heart. … I hope I don’t see him that much this year. I want to see him up there.”

Tomas goes yard in Aces loss

Yasmany Tomas’ eighth-inning homer was too little too late for the Aces.

Yasmany Tomas

Tomas jumped on a hanging fastball and launched it over the party zone in right field. He has six home runs on the season, tied with Kevin Cron for the team lead. Tomas went 1-for-4 with two RBIs on Wednesday.

The Aces had nine hits. Tim Locastro went 1-for-4 with a triple and RBIs. He made a diving catch in center field in the second inning. Locastro was optioned back to Triple-A on April 20.

Reno catcher Tyler Heineman made his first home start, going 2-for-3 with one RBI. Like Benito Santiago throwing from his knees, he erased two baserunners attempting to steal third base.

Second baseman Juniel Querecuto went 2-for-4 with an RBI. The ex-San Francisco Giant, shortstop Kelby Tomlinson, added two hits.

Fresno scored three runs in the first and fifth innings. Carter Kieboom heated things up on a breezy 75-degree night. The No. 24 ranked prospect by MLB Pipeline, Kieboom went 2-for-4 with a homer, double and two RBIs.

Grizzlies center fielder Collin Cowgill made a return to Greater Nevada Field. The outfielder had 13 homers and 70 RBIs at a .354 clip in 2011 for Reno. Cowgill finished 0-for-4 on Wednesday against his former team.

Fresno plated three runs in the first inning off Kieboom’s RBI double. The Aces responded with a two-run third inning off Locastro’s RBI triple to right-center.

The Grizzlies added two more in the fourth. Reno chipped into its deficit with another run in the bottom of the fourth. Fresno pulled away with three runs in the fifth and another in the seventh. Tomas’ two-run blast in the eighth marked the final runs for the Aces.

Today’s Game: Diamondbacks’ No. 2 pitching prospect, RHP Taylor Widener, will square off against veteran pitcher, Henderson Alvarez III, as the Aces look to even the series tonight against Fresno. Widener has struggled out of the gate, but holds a 3.17 career MiLB ERA and is due for a bounce back start. On the flip side, Alvarez has been down this road before starting his professional career back in 2007 in the Toronto Blue Jays system. He’s appeared in the big leagues six different seasons with his best season coming in 2014 where he was named an All-Star with the Miami Marlins going 12-7 with a 2.65 ERA. Alvarez threw a no-hitter for the Marlins in 2013.

NFL Draft: The First-Round of the NFL Draft kicks off tonight at 5 p.m. Pacific Time. The Aces have two baseball first-rounders on their team. Travis Snider is the highest draft pick with Reno being taken 14th overall in 2006 by the Toronto Blue Jays out of Mill Creek High School in Washington State. Snider has appeared in the big leagues eight different seasons for Toronto, Pittsburgh, and Baltimore. Right-handed pitcher, Braden Shipley was drafted 15th overall in the 2013 MLB draft out of University of Nevada, Reno by the Arizona Diamondbacks. He is the highest baseball draft pick from the University. He’s spent parts of three seasons with Arizona from 2016-2018. Archie Football:  Former Ace, Archie Bradley (’14-’16), was quite the athlete on the gridiron himself. In 2011, he was committed to play both football and baseball at the University of Oklahoma. He decided to forgo his OU scholarship after he was taken seventh overall in the first round of the 2011 MLB draft by the Arizona Diamondbacks out of Broken Arrow High School. He was committed to play quarterback and even competed in the 2010 Elite 11 QB camp for the nation’s top quarterback recruits. Teddy Bridgewater, Everett Golson and Cody Kessler were also at Elite 11 that year.

Yas-Bomb: Yasmany Tomas homered for the second consecutive game last night in the eighth inning. He now is tied for the team lead in home runs with Kevin Cron at six. However, Cron’s longest 2019 home run streak is three games from April 15-April 18. He was 7-for-14 with three home runs, seven RBI, and five runs scored during that stretch against El Paso and Albuquerque. T.G.I.T: The Aces have two wins this young season on Thursdays, tied for the most with Tuesday for their most of any single day in 2019. Reno also won their most games on Thursdays in 2018 with a 15-7 record and the second most games in 2017 with a record of 14-8.

On this Date – Honus Wagner: A Honus Wagner T206 baseball card, rated as a three on a scale from one to 10, is auctioned for $1.32 million in online bidding to an anonymous buyer. Robert Edward Auctions of New Jersey announced the same card, sold by an unnamed owner, fetched $791,000 at auction in 2008.

Summer is Coming: The forecast in Northern Nevada is saying it’s officially baseball season. Reno is slated to be 80 degrees or warmer both tonight and Friday. The weekend will cool off slightly, topping out at 78 Saturday and 73 Sunday according to weather reports.

Important Dates for Homestand: On Friday April 26, the Aces will welcome a number of Miss USA contestants to Greater Nevada Field. The contestants will sing the National Anthem, throw out ceremonial first pitches, and participate in in-game promotions. The Miss USA contestants will also participate in a meet-and-greet in the upstairs bar area prior to the game starting at 5:05 p.m. On Sunday, April 28, against Fresno, the club will hold its first Youth Baseball Day of the season welcoming Northern Nevada Little Leagues with first pitch slated for 1:05 p.m. The little league players will go through a chalk talk with an Aces player followed by an on-field parade. On Tuesday, April 30, it’s Education Day at Greater Nevada Field as the team will welcome various K-12 schools around Northern Nevada with first pitch set for 11:05 a.m.
