Mariners LHP prospect Kade Anderson recorded nine strikeouts over 5 1/3 innings for Double-A Arkansas on Friday.
The time to stash Anderson was weeks, if not months, ago. Now, his arrival in Seattle appears imminent, especially after the Mariners jettisoned veteran Luis Castillo at the trade deadline earlier this week. The 22-year-old pitching phenom, who was selected third overall in last year’s draft, has authored one of the most dominant professional debuts in recent memory, posting a microscopic 1.13 ERA and 0.65 WHIP with a staggering 128/12 K/BB ratio across 87 2/3 innings. Seattle can promote Anderson later next week while preserving his rookie eligibility for next season. Mariners president Jerry Dipoto told reporters earlier this week that he will work as a traditional starter, and won’t pitch in relief, when he jumps to the big leagues. At this point, all signs point toward Anderson making his major-league debut next week. Simply put, he has nothing left to prove in the minors and represents a must-roster arm in all fantasy leagues.
