“Last season, the Big Four broke hearts in the Southern League. The top-rated pitching prospects in the Seattle Mariners organization — Taijuan Walker, James Paxton, Danny Hultzen, and Brandon Maurer — combined for a 2.03 earned run average, striking out 424 batters and quashing opposing power with just 23 home runs allowed in 83 appearances.

The latest addition to the rotation, 20-year-old Walker, kissed his Double-A career goodbye last week with a 12-strikeout performance, granting six hits and an earned run in 6 2/3 innings pitched. The right-hander is slated to make his Triple-A debut on Tuesday against the San Francisco Giants’ Fresno Grizzlies — who, like the Rainiers, have had trouble harnessing run support in the first two games of the series.”
