By and large, spring training numbers are meaningless and not at all predictive. There’s too much noise. Pitchers are often working on specific things rather than trying to get outs, and so many at-bats and innings go to minor league players.
That said, every year there are spring numbers that jump out at you, and this year Angels reliever Blake Parker managed to strike out 24 batters in 12 1/3 Cactus League innings. He walked two. Furthermore, at one point he recorded 17 straight outs via strikeout.
With numbers like that, Parker had to make the team, right? Right. Parker did indeed win a spot in the Angels bullpen. He spent most of last season in Triple-A, though he did throw 17 1/3 innings with the Mariners and Yankees. Parker fanned 15 and had a 4.67 ERA (96 ERA+) in those 17 1/3 innings.
