Pablo Sandoval will almost assuredly not be one of the 26 players the San Francisco Giants choose for their Opening Day roster when they travel to San Diego in three weeks. The Giants already have a logjam of currently-good MLB players at the infield corners and designated hitter, happily exacerbated by the recent signing of Matt Chapman. They also have a logjam of intriguing unproven players and prospects on the 40-man roster who can hold down first and third base. And Sandoval’s comeback hasn’t gotten off the ground the way he envisioned: so far he’s 0-10 with two walks and seven strikeouts in Spring Training games.
