Dear Giants,
Eugenio Velez cannot hit left-handed pitching. He was unable to hit left-handed pitching in the minors, and he's been unable to hit it in the majors. Considering this, and considering that he isn't Ryan Howard against right-handed pitchers, he should not start for the Giants at any position.
Also, Velez's second half wasn't as good as you think it was.
Sincerely,
McCovey Chronicles
