With a playoff berth in the balance, the Mariners might need 18 innings out of Felix Hernandez this week, which would be just fine for fantasy owners.

2014

Subscribe now to see our 2014 outlook.

2013

It's not often a player goes from a complete non-factor to a $14 million contract in six months, but that was Iwakuma's fate in 2012. Iwakuma signed with Seattle out of Japan as a starting pitcher but was relegated to the bullpen to begin the season. It took 15 games for him to see his first action, and by June 1 - 54 games into the season - he had made just five appearances, mostly in low-leverage long-relief situations. He finally got his chance to start, though, in July, when the Mariners jettisoned Hector Noesi, and he more than held his own. He has good control (2.65 BB/9) and a decent strikeout rate (7.39), posting a 2.65 ERA in 16 starts. While his season home/road split is stark, as a starter he fared much better (2.56/2.80 ERA, .243/.254 BAA), and as a groundball pitcher (65.4 percent) he shouldn't be impacted by Safeco Field's reconfiguration this season. In addition to his two-year contract signed shortly after the season ended, Iwakuma enters spring training with a rotation spot locked up and looks like a good fantasy value this season.

2012

Iwakuma is considered to be Japan's best pitcher behind Yu Darvish and signed a one-year deal with the Mariners after becoming an international free agent. He tried to move to MLB last season but he wasn't able to agree to a contract with Oakland after the A's won his rights via the posting system. Iwakuma posted a somewhat disappointing season in 2011, with his 2.42 ERA tempered by a 6-7 record over only 119 innings pitched. He missed two months last season with a shoulder ailment, but returned in July and remained in his team's rotation through the remainder of the season. When he's on his game, Iwakuma has proven capable of using his forkball to generate plenty of swinging strikes and groundballs against NPB competition. The key to his MLB success will be continuing to command his forkball with the slightly different Major League baseball. Iwakuma doesn't have a great strikeout rate (just 6.8 K/9IP last season), but could provide quality innings as Seattle's No. 3 or 4 starter.

2011

Iwakuma was made available via the posting system by his team, the Rakuten Golden Eagles, and Oakland won the negotiating rights to the Japanese star with a bid reportedly in the $19 million range. After an apparently contentious series of negotiations, the two sides were unable to work out a deal, so Iwakuma will remain with Rakuten and the A's got their money back. Iwakuma will meet the service time requirements for international free agency early in 2011, and has already announced plans to move over to MLB. The groundballer had a very good year in 2010 with a 2.82 ERA and 1.095 WHIP in 201 innings pitched. He's considered to be Japan's best pitching prospect behind Yu Darvish, so he's one to keep an eye on with 2012 in mind.
