The Yankees' series finale in Detroit was one of three games rained out on Mother's Day yesterday. The game will be made up either July 24 or September 1. The former date would result in the Yankees playing 27 consecutive games coming out of the All-Star break.
The rainout gives the Yankees the option of bringing Ian Kennedy back to reclaim the fifth starters spot from Kei Igawa when it next comes due. Igawa was set to start on Wednesday, with Darrell Rasner pitching Thursday, but the rainout allows the Yankees to start Rasner on either Thursday or Friday with Igawa or a replacement starting the other day. Kennedy, who is eligible to be recalled on Thursday, was scheduled to start for Scranton Wilkes-Barre yesterday, but his game was also rained out. He'll start today, but if the Yankees pull him from the game early, could start on short rest against the Mets on Friday. It seems more likely to me that the Yankees will either start Igawa or a replacement on Thursday and let Rasner face the Mets on Friday.
The most likely Igawa alternate would be Steven White, who is on the 40-man roster and pitching well for Scranton (2.68 ERA, 1.21 WHIP), but White's extreme fly-ball rate and 4.02 BB/9 suggest he might just be a right-handed Igawa. It would be fun to see converted reliever Dan Giese get the call, but the Yankees would have to create room on the 40-man for him (possibly by calling up Francisco Cervelli and putting him on the 60-day DL, or better yet, by designating Chris Stewart for assignment). Me, I'd DFA Stewart and give the veteran Giese (1.05 ERA, 0.90 WHIP, 3.5 K/BB in six starts) a shot on Thursday with Rasner starting Friday.
