goの用法
米大リーグ インディアンスの公式Web siteは、松坂大輔投手とマイナー契約を結んだことを発表しました。開幕メジャー（２５人枠）を勝ち取れば、メジャー契約に切り替わるスプリット契約と呼ばれる形をとったそうです。今度こそがんばって汚名を払拭してほしいものです。
ところで記事のgo（ing）はどのような意味合いになるのでしょうか。Othelloくん、シンプルにお願いします。（UG）
Matsuzaka signs deal with Indians
Matsuzaka pitched in Japan from 1999-2006, going 108-60 with a 2.95 ERA for the Seibu Lions. The Red Sox won a bidding war over several teams to sign him and he went 15-12 in 32 starts in his first season in the AL.
He was dominant in 2008, going 18-3 with a 2.90 ERA and recording 154 strikeouts in 167 2/3 innings. He finished fourth in voting for the AL Cy Young Award.
But Matsuzaka's numbers have dropped alarmingly in the past four years. He has gone 17-22 with a 5.53 ERA and underwent Tommy John reconstructive elbow surgery in June 2011. He began last year in the minors before joining the Red Sox and going 1-7 with an 8.28 in 11 starts.
