Mariners pitching prospect Taijuan Walker made his major-league debut Friday, allowing just one unearned run on two hits and one walk while striking out two in five innings and picking up the win as the Mariners defeated the Astros, 7-1.
While the low strikeout total is a little surprising with the Astros' free-swinging ways and Walker's 10.2 K/9 ratio in the minors this season, he acquitted himself well in his debut. Next up should be the Royals Wednesday.
