And according to Oneri Fleita, that point will come when Prior can throw in the neighborhood of 5 innings/100 pitches. Makes perfect sense to me. No point in burning out the Iowa bullpen while Prior regains his armstrength and endurance. Agreed with the bullpen, but if he threw 4 innings/75-80 pitches that shouldn't be too much for a bullpen to cover, and he was getting to that point when he left spring training. One start isn't too big of an issue, but I hope it doesn't turn into more. 4 innings? I'd want my starters being able to at least six for my pen. Thats still five innings to make up, and while you usually carry a long reliever, it still puts unnecessary stress on a bullpen. Prior doesn't need to face AAA competition, he's proved he can get ML batters out, he just needs to keep pitching. How do you know that? How do you know there isn't still an injury that's sucking some velocity? An undetected one, perhaps? How long did Borowski try to pitch while doctors said nothing was wrong, only to eventually find out there was a shoulder problem? We don't really know what the deal with Prior is. He's at AAA because he's not up to the standards expected of him. I'd love to see him up too, but mostly I'd like to figure out why he never comes to ST ready to play.
