The San Francisco Giants said Tuesday that second baseman Marco Scutaro underwent a nerve block for his balky back, a procedure likely to land him on the disabled list to open the season.
According to MLB.com, Scutaro had the procedure—during which a specific nerve or nerve group is numbed—after missing almost all of spring training because of pain in his back.
Scutaro played three innings in one Cactus League game against the Los Angeles Angels on March 17.
The Giants open the regular season at Arizona on Monday and a DL assignment could be retroactive for up to 10 days, meaning Scutaro might only be sidelined for the first four games of the season.
Among potential replacements for Scutaro in the short term, Joaquin Arias had hit .319/.333/.319 in 47 spring at-bats with six RBI, Ehire Adrianza is at .250/.283/.523 in 44 at-bats with three homers and Brandon Hicks—a non-roster invitee to camp—is second on the club behind Buster Posey, hitting .381/.491/.762 in 42 at bats with seven doubles and three home runs.
