Jacob Lamb: Everything you need to know

Lamb (quadricep) will serve as the Giants' designated hitter and No. 5 batter in Sunday's Cactus League game against the Cubs. Before striking out in his lone at-bat as a reserve DH in Saturday's 7-3 win over the Royals, Lamb hadn't played since Feb. 27 while managing a left quad strain. He hasn't resumed playing defense, but his presence in the starting lineup Sunday suggests the quad injury isn't anything that will make or break his chances of winning a spot on the Opening Day roster. Lamb is attending Giants camp as a non-roster invitee after signing a minor-league deal in January.

Lamb will be shut down until at least Tuesday after being diagnosed with a left quad strain, Justice delos Santos of The San Jose Mercury News reports. Lamb will be re-evaluated Tuesday for a potential return to baseball activities. The veteran infielder is in camp as a non-roster invitee and is likely to begin the season at Triple-A Sacramento.

Lamb was removed from Thursday's Cactus League game against the Mariners due to left quad tightness, Justice delos Santos of The San Jose Mercury News reports. Lamb suffered the injury while trying to field a ball at first base in the seventh inning and had to come out of the game immediately afterward. Manager Bob Melvin said after the game that the team will know more about the severity of Lamb's injury Friday.
