SAN FRANCISCO -- The hits keep coming for the reeling Giants. Joaquin Arias was diagnosed with appendicitis Sunday night and had surgery. Arias was placed on the disabled list on Monday morning and infielder Nick Noonan was recalled from Triple-A Fresno.

No immediate timetable was given for Arias' return, but the surgery usually keeps big leaguers out for two to four weeks. Atlanta Braves right fielder Jason Heyward missed 23 games earlier this season after having the procedure but St. Louis Cardinals left fielder Matt Holliday missed just nine days in 2011. In 2010, Andres Torres missed two weeks after having an appendectomy.

Arias is hitting .282 in limited action this season. He has started to see more starts against left-handed pitchers, but has been hampered in recent weeks by a hamstring strain.

Noonan is driving up from Fresno and is expected to be available for Monday's series opener with the New York Mets. Noonan is hitting .212 this season while bouncing back and forth between the big leagues and Triple-A.
