The Arizona Diamondbacks' feel-good weekend ended on a sour note with injury concerns over starting pitcher Luke Weaver. Ketel Marte homered for the third time in three games, Eduardo Escobar had three hits, and the Arizona Diamondbacks tied a franchise record for scoring in a three-game series as they beat the San Francisco Giants 6-2 Sunday to finish a sweep. Weaver (4-3) left the game in the sixth inning with right forearm tightness after pitching five-plus innings of six-hit ball.
