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.
May 15 - 8:31 AM

Mariners prospect 3B D.J. Peterson went 2-for-5 with two homers and four RBI Sunday for High-A High Desert.

The 22-year-old hit a solo homer in the first inning, and then added a three-run shot in the fifth. Peterson, the No. 12 overall pick in last year's draft, has started to get hot at the plate since returning from a minor hamstring injury. He's batting .348/.375/.565 with six extra-base hits and 13 RBI in his last 10 games, including five multi-hit contests. Overall, Peterson has hit .298/.336/.468 with seven doubles, four home runs, 25 RBI and a 25/7 strikeout-to-walk ratio in 29 games for High Desert.
May 12 - 10:33 AM

Mariners prospect 3B D.J. Peterson was 2-for-5 with a double and three RBI Thursday for High-A High Desert.

The No. 12 overall pick in the 2013 draft, Peterson missed several games last week with a minor hamstring injury, but he's swung the bat well since returning, with a double, home run and four RBI in his past three contests. Overall, the 22-year-old is batting .277 with a .740 OPS, seven extra-base hits, 15 RBI and 17/5 strikeout-to-walk ratio in 20 games. Peterson is an advanced hitter with good bat-to-ball skills and above-average power, and therefore has the potential to reach the major leagues quickly. However, there's doubt as to whether he'll be able to remain at third base long term.
May 2 - 2:14 PM

Mariners prospect 3B D.J. Peterson left Tuesday's game for High-A High Desert with a tight hamstring and is considered day to day.

Peterson, 22, was off to a good start at High-A High Desert, batting .290 with one home run and 11 RBI in 17 games. Selected by the Mariners with the No. 12 pick in the 2013 draft, Peterson had his professional debut last summer come to an abrupt end after he was struck in the face by a pitch and required season-ending surgery for a broken jaw.
Apr 22 - 11:26 PM

Mariners 3B prospect D.J. Peterson is hitting .348/.400/.652 through six games with High-A High Desert.

Peterson has five errors in those six games, which could expedite his positional shift to first base. However, he is absolutely raking in his first full professional season, with two doubles, one triple, and one home run. Look for him to move up to Double-A in the next few months. High Desert is one of the best offensive environments in professional baseball, so his numbers will be inflated while he is there. Peterson has the potential to be a middle of the order slugger who could hit .300 with 25 home runs on an annual basis.
Apr 10 - 10:04 AM

Mariners prospect D.J. Peterson left Saturday's game against the Giants with an upset stomach after logging a single and a walk in his first two plate appearances.

"Won't play in night game," reports the Tacoma News' Bob Dutton, referencing the contest against the Dodgers. Peterson put up an impressive .303/.365/.553 slash line in the lower levels of Seattle's system last year, prompting Baseball Prospectus to ordain him the game's No. 65 prospect. The No. 12 pick in the 2013 draft should return to action shortly.
Mar 8 - 6:52 PM

Mariners prospect D.J. Peterson underwent successful surgery on Friday to repair a broken jaw.

Peterson sustained the injury in Thursday's game after being hit in the face by a fastball at Low-A Clinton. He will have to have his jaw wired shut, and will be out for at least the next six weeks, putting his availability for the Arizona Fall League in jeopardy.
