Sean O'Sullivan took a loss Friday against the Nationals after giving up four runs over five innings.

He fanned two and walked two in the loss. All of the runs came via the home run ball, as O'Sullivan served up a three-run shot to Bryce Harper in the first inning and a solo blast to Danny Espinosa in the fourth. The 27-year-old came into this season with a 5.91 ERA for his career, so there's not a lot of upside here. He figures to get the boot when Chad Billingsley (elbow) is deemed ready.
Apr 17 - 10:12 PM

Sean O'Sullivan pitched surprisingly well opposite Max Scherzer on Sunday, holding the Nationals to two runs over six innings in a no-decision.

Not to discredit O'Sullivan, but the Nationals entered the afternoon having scored the fewest runs in the National League with nine over their first five games. They managed two over the first nine innings on Sunday. Bryce Harper homered off O'Sullivan in the first inning and Wilson Ramos added a sacrifice fly in the fourth. Overall, the right-hander gave up five hits, walked one, and struck out five. The Phillies will have O'Sullivan pitch out of the fifth slot in the rotation while Chad Billingsley continues working in the minors, which means O'Sullivan is slated to take on the Nationals again on Friday, this time in Washington, D.C.
Apr 12 - 5:11 PM

Phillies purchased the contract of RHP Sean O'Sullivan from Triple-A Lehigh Valley.

He'll start on Sunday against the Nationals and Max Scherzer in what will be a pretty one-sided matchup. O'Sullivan will be the Phillies' fifth starter until Chad Billingsley (elbow) is ready.
Apr 12 - 10:13 AM

Sean O'Sullivan will start Sunday against the Nationals.

That was the assumption already, but it's now official that he'll be the fifth starter for the time being. O'Sullivan owns a 5.91 ERA over 231 1/3 innings in the majors and isn't a fantasy option.
Apr 9 - 4:11 PM

MLB.com's Todd Zolecki reports that Sean O'Sullivan "is the in-house favorite" to be the Phillies' No. 5 starter.

O'Sullivan was sent to minor league camp a couple weeks ago but is now back with the big leaguers, allowing four runs over four innings in a start versus the Blue Jays Tuesday. Many figure the Phils will find someone outside the organization, although general manager Ruben Amaro was being coy Tuesday, saying he didn't have interest in any of the recently released pitchers. O'Sullivan has a career 5.91 ERA over 231 1/3 frames in the majors and would be a candidate for worst starter in the big leagues should he make the rotation. Philly hopes to get Chad Billingsley (elbow) back by the end of April, so they might not need a No. 5 starter for more than a couple turns.
Mar 31 - 8:53 PM

Phillies reassigned RHP Sean O'Sullivan and C John Hester to minor league camp.

O'Sullivan had allowed seven hits and four earned runs in 3 2/3 innings this spring in the Grapefruit League. The 27-year-old righty is organizational relief depth.
Mar 16 - 9:05 AM

Phillies re-signed RHP Sean O'Sullivan to a minor league contract with an invitation to spring training.

O'Sullivan made three appearances with the Phillies this past season and posted a 4.30 ERA over 25 starts at the Triple-A level. The 27-year-old is useful depth to have around.
Mon, Dec 22, 2014 05:18:00 PM

Phillies released RHP Sean O'Sullivan.

O'Sullivan had been outrighted off the 40-man roster earlier in the week. He had a 4.30 ERA in 25 starts at Triple-A Lehigh Valley in 2014.
Wed, Oct 8, 2014 10:35:00 PM

Phillies sent RHP Sean O'Sullivan outright to Triple-A Lehigh Valley.

The move clears him from the 40-man roster. O'Sullivan made three appearances with the Phillies this season and had a 4.30 ERA in 25 starts at the Triple-A level.
Mon, Oct 6, 2014 04:24:00 PM

Phillies purchased the contract of RHP Sean O'Sullivan from Triple-A Lehigh Valley.

O'Sullivan has put up a 6.94 ERA over two spot starts for the Phils this season. He'll give them a mop-up man for the final month.
Fri, Sep 5, 2014 01:59:00 PM

Sean O'Sullivan has accepted his assignment to Triple-A Lehigh Valley.

O'Sullivan could have elected to become a free agent, but he will instead remain in the Phillies' organization. The right-hander was shelled for five runs over six innings in a spot start last Thursday against the Astros.
Wed, Aug 13, 2014 04:54:00 PM

Phillies sent RHP Sean O'Sullivan outright to Triple-A Lehigh Valley.

It's the second time he's been designated for assignment by the Phillies and cleared waivers in the last month. He seems likely to again accept the assignment rather than declare free agency.
Wed, Aug 13, 2014 08:52:00 AM

Phillies designated RHP Sean O'Sullivan for assignment.

O'Sullivan allowed five runs over six innings in a spot start Thursday. He'll be replaced in the Phillies' rotation by Jerome Williams.
Sun, Aug 10, 2014 02:04:00 PM

Sean O'Sullivan made an emergency start against the Astros on Thursday and struggled, allowing five runs over six innings but didn't factor into the decision as the Phillies came from behind late to win 6-5.

The Phillies traded Roberto Hernandez, slated to start Thursday's match against the Astros, to the Dodgers in the afternoon. O'Sullivan scrambled to get to Citizens Bank Park on time, and the Astros -- particularly Chris Carter, who homered twice -- had his number. The right-hander gave up seven hits and a pair of walks while striking out four. It's unclear if he'll stick in the rotation with Hernandez gone, but the two starts he has made for the Phillies this season won't help his cause.
