It hasn’t been a strong year down on the farm for the Seattle Mariners. As I’m putting the finishing touches on the Mid-Season Prospect Rankings I’m reminded of the season-long struggles of many of the club’s better young talents. Tuesday, however, was one of the solid days of the year in that regard.

No, not every top prospect went 4-for-4, hit three homers or lasted seven shutout innings — heck, one of the affiliates didn’t even play (Double-A Jackson) — but there were a number of notable lines — enough to compel me to type a few hundred words to highlight them.

Tacoma (AAA)
Chris Taylor: 2-3, 2 BB, SB
Season: 47 G, .285/.359/.404, 9-2B, 4-3B, 2 HR, 23 BB, 34 SO, 12 SB

Jesus Montero: 4-5, 2B
Season: 76 G, .314/.351/.489, 11-2B, 2-3B, 13 HR, 18 BB, 61 SO

Bakersfield (A+)
Tyler O’Neill: 2-4, HR
Season: 62 G, .248/.282/.492, 10-2B, 3B, 16 HR, 10 BB, 83 SO

Everett (SS-A)
Corey Simpson: 3-4, 2-2B
Season: 12 G, .292/.327/.521, 5-2B, 2 HR, 3 BB, 14 SO

Alex Jackson: 2-4, HR, SO
Season: 11 G, .282/.364/.436, 3-2B, HR, 4 BB, 13 SO (Everett)

The status of the Mariners’ system is down, even from the start of the year when it was thin with which to begin. The club since has traded Gabby Guerrero and almost every one of the organization’s top hitters that opened the year with a full-season club has struggled. Ketel Marte and Tyler O’Neill are the two exceptions. O’Neill isn’t hitting for average yet and he’s swinging and missing far too often, but at 19 in Advanced-A, he’s holding his own.

D.J. Peterson is the biggest disappointment. More on that in the Mid-Season Rankings update later this week, and warning: It’s not pretty.

But for Tuesday, it was a solid day in the minors for the Mariners. Besides, as one of the closest friends in the game of baseball told me once, it’s a good day in the minors when the big clubs wins, and M’s shut out the Padres 5-0.
