Walker was recently promoted from Double-A and has been turning heads all year. In his first start at the Triple-A level, Walker pitched an absolute gem. He lasted just six innings, but surrendered only three total hits, walked two batters, and didn’t allow a single run.
In his second start, Walker had a very similar outing. He threw five more innings of scoreless ball, while giving up just two hits and two walks. The righty struck out eight batters as well, which gives him 12 K’s through his first 11 innings of Triple-A ball.
Walker was 4-7 before his promotion, but it wasn’t because of his individual performance. He had a sizzling 2.46 ERA in Double-A and was limiting hitters to an embarrassing .195 batting average. He struck out a ridiculous 96 batters through 84 innings of work and quickly proved that he deserved to be promoted.
The only thing standing in Walker’s way is his aging competition. Starters Joe Saunders, Aaron Harang, and Jeremy Bonderman all occupy the bottom of Seattle’s rotation at the moment. Walker is clearly the better pitcher among the four, so it is basically up to when the organization feels the kid is ready.
The righty is perhaps the most promising pitching prospect yet to make his major-league debut. However, the way he pitching right now, it is only a matter of time until Walker is striking out major league hitters.
