Mariners general manager Jack Zduriencik said Wednesday that prospect D.J. Peterson will get a "fair shot" to crack the Opening Day roster next spring.
Peterson, the M's first-round pick in 2013, posted a .912 OPS with 31 home runs and 111 RBI in 123 games this season between High-A High Desert and Double-A Jackson. "His age and experience might be working against him," Zduriencik said, "but this is also a pretty good hitter. You don't shut the door on it. You leave it open and see what he does." Peterson will likely be auditioning at first base, as he's blocked at third in Seattle by Kyle Seager. Oct 2 - 9:12 AM

Mariners prospect 3B D.J. Peterson was a combined 4-for-7 with two home runs and five RBI on Tuesday in a double header for Double-A Jackson.

The No. 12 overall pick in the 2012 draft, Peterson is batting only .224 in 17 games in August but still has clubbed five home runs. The 22-year-old has put up impressive numbers this season (his first full professional season) overall, with a .300/.365/.561 batting line, 28 home runs, 30 doubles and 102 RBI in 111 games between High-A High Desert and Double-A Jackson. The Mariners are aggressive with their top prospects, so a September call-up can’t be completely ruled out. However, a debut in mid-2015 seems more realistic.
Aug 20 - 2:40 PM

Mariners prospect 3B D.J. Peterson went 2-for-5 with a home run, double and two RBI on Sunday for Double-A Jackson.

Peterson was mired in a slump entering Sunday, as he was just 2-for-28 (.071) with one extra-base hit and 13 strikeouts over his previous eight contests. However, that shouldn’t detract from the 22-year-old’s impressive overall season. Through 97 games between High-A High Desert and Jackson, Peterson is batting .306/.363/.566 with 24 homers, 30 doubles and 92 RBI. The Mariners are aggressive with their top prospects (see Mike Zunino in 2013), so it’s conceivable that Peterson could get a look in the major leagues if the organization believes he can improve their offense down the stretch. That being said, a call-up during the 2015 season is probably more realistic.
Aug 4 - 4:49 PM

Mariners prospect third baseman D.J. Peterson (wrist) could return to action as soon as Tuesday.

Peterson left Saturday's game with a bruised left wrist, but it's not a major concern. The 22-year-old has batted .318/.375/.586 with 23 home runs and 89 RBI over 91 games this season between High-A and Double-A.
Jul 29 - 2:30 PM

Mariners third base prospect D.J. Peterson went 2-for-4 with a home run for Double-A Jackson on Wednesday.

After hitting .326/.381/.615 over 65 games with High-A High Desert, Peterson has hit .312/.363/.527 with five doubles and five home runs with Double-A Jackson. He has continued to hit at a high level despite playing in a more neutral offensive environment and the more advanced pitching in Double-A. Peterson profiles as a slugging corner infielder who hits for a solid average with good power, though he may need to move across the diamond to first base if he does not improve his defense. Either way, his bat has the potential to make him a perennial All-Star at any position.
Jul 24 - 9:22 AM

Mariners prospect 3B D.J. Peterson went 3-for-5 with a home run on Thursday for Double-A Jackson.

Peterson has continued to hit up a storm since his promotion to Double-A Jackson late last month, as he's batted .324/.360/.549 with eight extra-base hits (four home runs) in 17 games at the more advanced level. Furthermore, the 22-year-old is currently riding a nine-game hitting streak during which he's batting .410 with a 1.208 OPS and four home runs. On the season, Peterson has batted .326/.377/.602 with 22 home runs, 27 doubles and 81 RBI in 82 games between High-A High Desert and Jackson.
Jul 18 - 3:18 PM

Mariners 3B prospect D.J. Peterson went 2-for-4 with a double and a walk for Double-A Jackson on Friday, raising his Double-A line to .290/.333/.500.

After a slow start, Peterson is in the midst of a seven-game hitting streak during which he has hit .367/.406/.733 with two doubles and three home runs. He has the potential to be a middle of the order slugger who hits 20-plus home runs on an annual basis since Raul Ibanez in the mid-2000s. Peterson will likely spend the rest of the season in Jackson, and should be playing for the Mariners at some point in 2015.
Jul 12 - 11:18 AM

Mariners third base prospect D.J. Peterson went 2-for-5 with a home run for Double-A Jackson on Saturday.

The home run was his first home run in Double-A Southern League. Peterson has hit .268/.302/.390 in Double-A, and it will be interesting to see how he hits in the more neutral offensive environment of the Southern League and against better pitching. Peterson is likely to finish 2014 in Jackson, and could be in Seattle in mid-2015.
Jul 6 - 10:11 AM

Mariners third base prospect D.J. Peterson has been promoted to Double-A Jackson.

In his last game for High-A High Desert, Peterson went 1-for-4 with his 18th home run of the season, and has hit .442/.500/1.023 with seven doubles and six home runs during his 10-game hitting streak. He ends his time in the California League with a .326/.381/.615 slash line. Peterson's ability to adjust to better pitching in Double-A, particularly the higher quality off-speed pitches, will dictate how quickly he reaches Seattle, but the most likely outcome is a mid-2015 call-up.
Jun 24 - 8:48 AM

Mariners prospect 3B D.J. Peterson extended his hitting streak to nine games on Sunday, going 2-for-4 with a home run, double and three RBI for High-A High Desert.

The 22-year-old has absolutely terrorized California League pitching this season and especially as of late, as he's batting .462/.523/1.026 with seven doubles, five home runs and 20 RBI during his current hitting streak. He's also collected at least two hits and two RBI in eight of those contests. It's a safe bet that Peterson will receive a promotion to Double-A Jackson sometime soon, as he clearly has nothing left to prove at the High-A level with a .327/.383/.610 batting line, 23 doubles, 17 homers and 71 RBI through 64 games.
Jun 23 - 12:57 PM

Mariners third base prospect D.J. Peterson went 2-for-3 with a double and two walks for High-A High Desert on Friday, raising his season line to .323/.379/.596 with 21 doubles, one triple, and 16 home runs.

Peterson has 14 hits in his last seven games, and is hitting .393/.464/.803 with seven doubles and six home runs in the month of June. He has 49 total bases in 15 games, and sports an OPS of 1267. Peterson must be "working on something" in the California League, because he has shown a mastery of the pitching at this level.
Jun 21 - 11:31 AM

Mariners third base prospect D.J. Peterson went 2-for-5 with a double and a home run for High-A High Desert on Monday, raising his season line to .306/.359/.553 with 17 doubles, one triple, and 13 home runs.

Peterson's 56 strikeouts in 256 plate appearances (21.9%) are a bit of a concern, but he will need to be promoted to Double-A Jackson before he will be challenged. Peterson has the potential to hit 20-plus home runs and hit .300, but will need to improve his pitch recognition before he will be successful.
Jun 10 - 10:18 AM

Mariners third base prospect D.J. Peterson went 3-for-4 with a double and a walk for High-A High Desert on Wednesday.

Peterson has been on fire as of late, as he is in the midst of a 10-game hitting streak, and has hits in 12 of his last 13 games. He is hitting .415/.492/.887 with seven doubles and six home runs over his past 13 games, raising his season line to .313/.365/.551. Peterson was one of the most advanced college bats in the 2013 draft, and he should be in Double-A by the end of the month.
Jun 5 - 9:34 AM

Mariners third base prospect D.J. Peterson hit his 10th home run of the season as part of a 3-for-4 night for High-A High Desert on Wednesday.

Peterson has been on a power surge as of late, hitting five home runs in his past six games, putting up a .333/.429/1.000 line to raise his season line to .286/.335/.514. He has 10 doubles and a triple for the season. He has too much swing-and-miss in his game, as is indicated by 43 strikeouts in 44 games, but he frequently makes hard contact and has a lot of raw power which he is able to use in game situations. He has the potential to hit in the middle of a championship caliber line-up, but will have to work to make more contact to reach his potential.
May 29 - 9:35 AM

Mariners prospect third baseman D.J. Peterson hit his fifth home run of the season on Wednesday night to push his season line to .295/.331/.477 for High-A High Desert.

Since he missed a week due to a strained hamstring, Peterson has been hitting well, hitting .302/.323/.556 with 4 home runs, four doubles, and three stolen bases over 14 games. He has paired with Gabriel Guerrero to form a potent 3-4 punch, and they could be the next big sluggers in Safeco Field.
