For all of the buzz that's been rightfully bestowed upon Mariners top pitching prospect Kade Anderson, let's not overlook their No. 2 pitching prospect Ryan Sloan, because he is having a fantastic season as well. That continued Saturday.

Kade Anderson has reached the point where dominance in his starts is no longer a surprise but rather the expectation. Baseball's top-ranked pitching prospect twirled 5 2/3 scoreless innings and struck out seven on Friday night, extending a scoreless streak that dates back more than five weeks for Double-A Arkansas,

HOUSTON -- Colt Emerson was indeed removed from the Mariners’ active roster ahead of Friday’s huge series against the Astros at Daikin Park. However, it was for a stint on the injured list and not being optioned to Triple-A Tacoma, as was initially the club’s plan.

SEATTLE -- The midseason re-ranks are out at MLB Pipeline, and although the Mariners didn’t have a significant shakeup like last year, the takeaway from the top of the farm is those players’ closer proximity to the Majors. And the headliner of this group -- left-hander Kade Anderson -- remains

If changes in scenery can create a spark, Boston Smith has been completely energized by his first week in a new organization. The Mariners acquired Smith at the Trade Deadline in the deal that sent Luis Castillo to the White Sox. And Seattle’s No. 14 prospect has been showing off

Kade Anderson is on another level this season. MLB’s No. 5 prospect turned in yet another masterful performance, punching out nine over 5 1/3 scoreless innings in Double-A Arkansas’ 4-0 win over Amarillo on Friday at Dickey-Stephens Park.

Lazaro Montes continued to show off his big-time power on Tuesday, reaching the 30-homer mark for the second consecutive season, and he did it in an emphatic way. Montes whacked a pair of home runs, his first multi-homer game since a July 7 promotion to Triple-A, to go along with

SEATTLE -- The Mariners are on the board in this Trade Deadline season, and they made the move that they’d hoped to make all along. Seattle is sending veteran right-hander Luis Castillo to the White Sox, the club announced on Saturday night, shortly after multiple sources confirmed to MLB.com that

The number of adjectives that can properly describe Kade Anderson's dominance in his first pro season is dwindling faster than his WHIP. The Mariners' top-ranked prospect continued his mastery on the mound with seven strikeouts over five perfect frames to spearhead Double-A Arkansas' 8-0 blanking of Tulsa at Dickey-Stephens Park

SEATTLE – T-Mobile Park has never carried the reputation of being an appealing environment for hitters. Quite the opposite, actually. Ace Reese, however, seemed to have no problem ripping a few out over the wall during batting practice Tuesday before the Mariners’ game against the Reds.
