Jason Vargas SP KC 8 Hrs

Jason Vargas (appendectomy) could rejoin the Royals' rotation on Saturday in Oakland.

Vargas threw a four-inning simulated game on Tuesday with no issues. "He threw four innings, 15 pitches each inning. He had much more life on his pitches, much better command on his pitches, so he looked really good," manager Ned Yost said. Yost said "we'll see" when asked about Vargas starting Saturday, but it sounds like the club is leaning that way. We'll know for sure in a day or two.

Jason Vargas (appendectomy) will throw a simulated game on Saturday.

Vargas didn't feel quite right during a bullpen session Wednesday, so the Royals are pumping the brakes on him a bit rather than activating him to start Sunday. He's not expected to need a rehab assignment, so Vargas could conceivably rejoin the rotation sometime next week.

Jason Vargas (appendectomy) is unlikely to start Sunday.

Vargas still doesn't feel quite right after undergoing an appendectomy in early July. The left-hander will aim to return to the Kansas City rotation late next week.

Jason Vargas (appendectomy) threw a 20-pitch bullpen session Monday.

Jason Vargas (appendectomy) could rejoin the Royals' rotation later this week.

Vargas played catch up to 110 feet Saturday and is expected to throw a short bullpen session Wednesday. He might only need one additional 'pen session after that before rejoining the rotation, as he's not expected to go out on a rehab assignment. "He still feels a little stretching sensation in there," manager Ned Yost said Saturday. "He'll be fine." Vargas is just 11 days removed from his projected 3-4 week timetable, so a return later this week would be sooner than expected.

Jason Vargas (appendectomy) is not expected to need a rehab assignment before rejoining the Royals' rotation.

He's not close to returning, however, as Vargas is only a week removed from a 3-4 week timetable following an appendectomy. The left-hander is not with the Royals on their road trip but has been playing catch.

Royals head trainer Nick Kenney said the team is prepared to be without Jason Vargas for three to four weeks.

It was discovered Wednesday that Vargas needed an emergency appendectomy, and it appears the tam isn't expecting him back before the end of July. Bruce Chen will likely start in his place during his absence.

Jason Vargas allowed two runs on six hits over 5 2/3 innings in a loss to the Rays on Tuesday.

Vargas kept the Rays off the board until the sixth inning, when an Evan Longoria two-run single did all the damage he would allow. The left-hander walked two while striking out three. It's generally been a good first half for the 31-year-old, as he owns a 3.31 ERA and 1.23 WHIP heading into his last start of the first half against the Tigers on Sunday.
