The Phillies need at least one innings eater, whether Pedro signs or not. Arroyo wouldn't do well in that bandbox, but Harang might.
The Dodgers have two bullpen guys on the shelf and also need another starter. Cordero, Rhodes, and Weathers would look good there, as would Harang or Arroyo.
The White Sox need an IF with pop or a CF. This may be the only team that would take gamble on Willy Taveras. Please, for the love of God. He's fast, Mr. Williams. Perhaps Taveras and Phillips?
The Yankees need a fifth starter. Arroyo might lead the AL in HR allowed in half a season. Harang would look good in pinstripes, too.
The Rays need a catcher and a couple pitchers. Hernandez for Brignac?
The Tigers need a fifth starter and a closer. Arroyo would likely thrive in Detroit. So could Cordero. Can they afford the contracts?
The Twins need a 2B in the worst way, but don't like to spend the cash. Phillips fits their needs like a glove.
The Mariners need a catcher. Hernandez would be a nice fit out there.
The Rangers need a fifth starter. They have no cash to spend, though. How about Maloney and Ramirez for a catcher?
The Angels need an OF and a starter. Arroyo could be league average or better innings eater in the AL West and Gomes might also appeal to them.
The Giants need a 2B. Phillips for Posey? I'd do it.
The Mets needs relievers and starters. Arroyo and Cordero or Rhodes or even Weather would be a good fit.
