Vargas got a start at first base late in summer camp, Nick Piecoro of the Arizona Republic reports.

EDGE Analysis

Vargas displayed a big bat during summer camp and the exhibition games in Los Angeles, which has manager Torey Lovullo thinking creatively about how to get him in the lineup. The switch-hitting utility infielder has a career .968 OPS against left-handers, which Lovullo might be able to exploit. Vargas came up as a middle infielder and played third base, but he's blocked at those spots. That leaves first base -- already the domain of Christian Walker (groin) -- and designated hitter.
