The Mariners have agreed to sign right-hander Hisashi Iwakuma to a one-year contract worth $1.5MM, reports ESPN's Jerry Crasnick (all Twitter links). The deal includes $3.4MM in incentives based on starts and innings pitched. We heard the two sides were closing in on a deal earlier this week. Iwakuma is a Sosnick-Cobbe client.
The Rakuten Golden Eagles posted the 30-year-old righty a year ago and the A's won the rights to negotiate with him for $19.1MM. However, the sides didn't work out a deal and Iwakuma re-signed with Rakuten. He posted a 2.42 ERA with 6.8 K/9 and 1.4 BB/9 in 119 innings in 2011 and became a true free agent after the season. He figures to join Felix Hernandez, Jason Vargas, and Michael Pineda in Seattle's rotation with Blake Beavan and Charlie Furbush as candidates for the fifth spot.
