The Orioles are pushing back their rotation to make room for Chris Tillman, who is being recalled from Triple-A Norfolk and will pitch Sunday against the Tampa Bay Rays.

Brian Matusz, who was scheduled to pitch Sunday, will be pushed back to Monday, and Jake Arrieta, Monday's scheduled starter, is expected to pitch Tuesday in New York now.


Arrieta had his normal side session today scrapped by the team, which gives further proof that he won't be pitching until Tuesday at least.

So, at least for now, there will be a six-man rotation. Things will get complicated because the Orioles have three off days from Sept. 9 to Sept. 23, so, if they stayed with a six-man rotation, the pitchers would be on six days rest.

The Orioles would also like to get a look at Rick VandenHurk as a starter, so expect some shutting down and maneuvering over the next few weeks as some of the young guys near their career high for innings.

Here is a quick list, courtesy of the hard-working Jeff Z, on current innings and career highs for the four young Orioles starters:

ARRIETA: 73 IP at Triple-A; 88 at majors. Total now, 161; Previous pro high, 150 2/3 IP in 2009

MATUSZ: Total now, 150 2/3 IP; 157 2/3 last year in first pro season

BERGESEN: 136 2/3 IP this year in majors; Total now, 151 1/3 IP; Pro high is 165 1/3 in 2008.

TILLMAN: 121 1/3 IP this year in minors; Total now, 146 1/3 IP; Pro high is 161 2/3 in 09

One other thing: Adam Jones (shoulder) is unavailable today. He had a shot in his ailing left shoulder Thursday and is still being listed as day-to-day. No minor-league recall is imminent, but could still happen.
