Mariners 1B prospect D.J. Peterson plated four runs Monday in a win for Triple-A Tacoma.

Peterson's three-run homer in the first inning was his first since July 17. The 24-year-old entered Monday's game in a 1-for-15 rut that dropped his average from .309 to .277. Despite the recent power outage, Peterson has had a fine season, hitting .275 with 17 round-trippers and 72 RBI over 103 contests for Tacoma and Double-A Jackson. Peterson has played exclusively at first base this year after spending the bulk of his early minor league career at the hot corner.

Mariners 3B prospect D.J. Peterson went deep for the third straight game Tuesday in a win for Triple-A Tacoma.

Peterson pounded a three-run homer in the eighth inning and also contributed an RBI groundout. The 24-year-old has hit a ridiculous .440 with six homers and 20 RBI during his 13-game hitting streak. He hasn't missed a beat since his promotion to Triple-A last week, batting .417 over his first 24 at-bats. Before his call-up, the 2013 first-round pick was fifth in the Southern League in doubles (21) and sixth in slugging percentage (.466).

Mariners 3B prospect D.J. Peterson finished a triple shy of the cycle Monday in a win for Double-A Jackson.

He's hit .500 with four RBI during his four-game hitting streak. Peterson has upped his average from .213 to .242 over that span. The 24-year-old smacked 31 homers in 2014 but came crashing back to Earth with only seven in 2015. The former first-round pick is a .269 career hitter in the minor leagues.

Mariners prospect 3B/1B D.J. Peterson went 2-for-4 with a home run, double and two RBI on Wednesday for Double-A Jackson.

The home run was just his third of the season, and it was his first since May 27. Peterson is off to a rough start this season back at Jackson, batting .212/.292/.317 with 15 extra-base and 25 RBI through 55 contests. It is worth noting, however, that the 23-year-old’s strikeout (22.7%) and walk rates (9.4%) are close to his career averages, and his current .268 BABIP suggests his triple-slash line is bound to improve. Plus, Peterson has at least shown some improvement at the plate with each month, posting a .510 OPS in April (18 games), followed by a .632 OPS (26 games) and now a .731 OPS in June (11 games).

Mariners prospect 3B/1B D.J. Peterson went 2-for-4 with a home run and four RBI on Wednesday for Double-A Jackson.

The home run was just the second of the year for Peterson, who slugged 31 in 2014 between High-A High Desert and Jackson. Even more concerning is the fact that the 23-year-old is batting just .213/.282/.305 with a 44 strikeouts through 42 games. But while it’s been a slow and disappointing start to the season for the 2013 first-round draft pick, his strong track record as a professional suggests his production will eventually pick up.

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.

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.
Wed, Aug 20, 2014 02:40:00 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.

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.
Tue, Jul 29, 2014 02:30:00 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.

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.

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.

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.

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.
