Hot – D.J. Peterson – 1B

2015 has been extremely concerning for D.J. Peterson, however he has performed much better in July. Peterson is hitting .266 with 3 doubles, 1 home run, 8 RBI’s and 1 stolen base across 16 games this month. The 23-year-old is falling well short of expectations this season, as he is hitting just .222 with 6 home runs and 40 RBI’s. He remains one the M’s most promising prospects, but it is hard to overlook his problems at the plate this year.

Hot – Edwin Diaz – RHP

This talented young hurler represented the Mariners at the recent Futures Game in Cincinnati, and it is obvious why he was selected to participate in the event. Edwin Diaz is only 1-2 in July, but his 2.45 ERA across 18.1 innings is very impressive. The 21-year-old has fanned 18 and walked 3, while allowing 0 home runs. Diaz is one of the most exciting young players the M’s have, and I have a feeling his name could come up in trade rumors as July 31st approaches.

Not – Julio Morban – OF

Julio Morban has had a rough season. Originally thought to have an outside chance of making an impact with the M’s in 2015, Morban’s stock has fallen fast. The 23-year-old has posted a miserable .170 batting average in July, with 2 doubles and 3 RBI’s. The Mariners have made it clear this year that Morban’s long term future with the organization in tentative at best.

Hot – Tyler Marlette – C

Tyler Marlette has turned it on with the Generals in July, registering a .353 batting average with 2 doubles, 1 home run and 4 RBI’s. Marlette’s 24% caught stealing percentage is not very good, but his .994 fielding percentage suggests he is strong behind the plate defensively. 2015 has been a an up and down season for the top prospect, but hopefully he can build on his recent success going forward.
