Athletics Rumors: Iwakuma, Matsui, Duchscherer

The San Francisco Chronicle's Susan Slusser has some updates regarding Oakland's offseason plans:

• Oakland increased its offer to Japanese righty Hisashi Iwakuma, but the two sides were still unable to agree on a deal. Iwakuma was looking for around $12MM per season, and the A's were unwilling to spend more than $36MM, including the posting fee. The A's will have interest in Iwakuma again next offseason, when he is a free agent and doesn't require a posting fee.  However, relations may be strained after Iwakuma's agent Don Nomura told the AP the A's "never showed any respect" toward his client.
• The A's may take the $19.1MM posting fee that will be returned and focus on other areas, including Hideki Matsui. Oakland GM Billy Beane met with Matui's agent, Arn Tellem, Monday at the Winter Meetings. According to Slusser, Matsui has "strong interest" in playing for the A's. Derrek Lee and Nick Johnson are potential alternatives.
• According to this tweet from Slusser, if the A's look to add a veteran starter, it may be a familiar face, coming in the form of Justin Duchscherer.
