Mariners shortstop prospect Ketel Marte putting together nice season

Seattle Mariners shortstop prospect Ketel Marte is quietly putting together a very impressive season at Double-A Jackson – one that could get him ranked as one of the Mariners top-ten prospects going into 2015.

The 20-year-old switch-hitter has been Jackson’s starting shortstop since opening day, and he has maintained a .300 batting average all season long while playing against older competition in the Southern League.

Marte had four two-hit games this week, improving his season average to .304 while raising his league-leading hits total to 133. He’s hit 27 doubles, four triples, and two homers while stealing 23 bases.

Marte makes contact at a good rate, striking out just 63 times in 467 plate appearances. He hasn’t walked much, drawing just 19 free passes.

A look inside the numbers reveals a lot of consistency. His statistics are nearly identical from each side of the plate: he’s batting .290 with one homer right-handed, and .306 with one homer from the left side. He hit .302 in the first half, and is batting .306 in the second half. His home/road splits are also close to even.

The Dominican is listed at 6-foot-1, 180 pounds. The Mariners are hoping that he continues to build strength which would result in additional power.

Defensively, Marte has worked to cut down his errors as the season has progressed. He made 29 errors this season, but 25 of them came in the first three months of the season. He has just four miscues in his last 35 games.


After a brief journey to the International League, W.F West High School graduate Brock Peterson is back in the PCL.

The Chehalis native was playing for Syracuse until early July, when the parent Washington Nationals sold his contract to the Los Angeles Dodgers. The Dodgers assigned Peterson to Triple-A Albuquerque, where he found himself in a new situation.

Peterson played for Memphis in 2013, where he hit 25 home runs to lead the PCL and earn his first major league call-up. He spent all of September with the National League Champions St. Louis Cardinals, collecting his first two major league hits.

“After playing for 12 years, last year was the first year I played west of Iowa,” said Peterson, who signed with the Minnesota Twins in 2002. “It was really cool to have friends and family get a better opportunity to come see me play.”

In his first 33 games for Albuquerque this season, he’s batting .368 with six homers and 26 RBIs.
