Giants pitcher Tim Lincecum is being sued by his former landlord, who accuses him of trashing his furnished San Francisco apartment — stealing and destroying at least $200,000 worth of household items.

In a lawsuit filed Wednesday in San Francisco Superior Court, landlord Mindy Freile alleged that shortly after Lincecum’s lease expired at 141 Hampshire St., the star pitcher returned to living in the apartment where he later “broke, stained, defaced, tore, injured or destroyed” her property.

Lincecum’s Los Angeles-based agent Rick Thurman called it an “unwarranted lawsuit,” adding, “I’m not going to dignify it with a response.”

Among the items damaged or taken were “bedding, doors, carpet, pillows, kitchenware, linens, furniture, household appliances, art work, decorations, patio furniture, lights, lamps, and mirrors, among other things,” according to the complaint.

“My belief is there was some kind of party that left it in really bad condition,” said Freile’s attorney Jonathan Bornstein. “Maybe there’s a perfectly good explanation on his side, but we haven’t heard it yet.”

The complaint, which seeks $350,000 in damages, also states that Lincecum failed to pay rent on time and stole and destroyed his landlord’s personal property and papers. “Things were missing,” Bornstein said. However the attorney added that he didn’t know if Lincecum had taken the items or somebody else had.

The Giants wouldn’t comment on the lawsuit.

According to the complaint, Lincecum signed a lease in May 2010 to rent a unit in the Mission District townhouse. Shortly after the lease expired Feb. 28, Lincecum reoccupied the unit without his landlord’s permission and stayed through May 13, Bornstein said.

The landlord, who had been trying to evict Lincecum, then entered the unit to find it damaged. Bornstein said the landlord filed suit after failing to get a resolution from her insurer and hoped the lawsuit could be settled through mediation.
