Sean O'Sullivan has elected to become a free agent.

O'Sullivan was pushed off Boston's 40-man roster in August after registering a 6.75 ERA in 21 1/3 innings out of the Red Sox bullpen. The 29-year-old right-hander will likely have to settle for a minor league contract on the open market.

Red Sox activated RHP Sean O'Sullivan from the 15-day disabled list; sent him outright to Triple-A Pawtucket.

O'Sullivan is recovered from his left knee tendinitis, but the Red Sox don't have a spot for him in the major leagues at the moment. The right-hander holds a 6.75 ERA in 21 1/3 innings this season with Boston.

Red Sox placed RHP Sean O'Sullivan on the 15-day disabled list with left knee tendinitis.

That clears a spot for Brad Ziegler on the active roster. O'Sullivan must have suffered the injury Friday when he logged five innings against the Rays. The Red Sox haven't announced who will take his spot in the starting rotation, though Eduardo Rodriguez will probably get first crack at it.

Sean O'Sullivan was charged with four runs in five innings in a no-decision against the Rays on Friday, giving up seven hits and a walk while whiffing four.

His ERA rises to 6.75 with a hefty 1.69 WHIP to match. O'Sullivan was making his fourth start and probably won't get many more. The Red Sox are expected to shop heavily for starting pitching this month.

Sean O'Sullivan will start Friday against the Rays.

He'll get the nod over Clay Buchholz, who will head back to the bullpen for the time being. O'Sullivan allowed two runs over five-plus innings in a spot-start against the Angels on Sunday, but he doesn't come recommended in fantasy leagues.

Sean O'Sullivan pitched a serviceable game in Sunday's win over the Angels, allowing two runs on four hits over five-plus innings.

O'Sullivan was called up on Saturday to fill in for Eduardo Rodriguez, who fell out of starting favor earlier in the week. Against the Angels, he struck out two and walked three. Both runs on O'Sullivan's line scored after he trotted out to start the sixth inning. The 28-year-old right-hander has been splitting time between the Red Sox and Triple-A Pawtucket throughout the season. With the big league club, he holds a terrifying 6.61 ERA and 1.71 WHIP over 16 1/3 innings. There is no fantasy intrigue here.

Red Sox recalled RHP Sean O'Sullivan from Triple-A Pawtucket.

O'Sullivan will take the hill Sunday versus the Angels. He's filling in for Eduardo Rodriguez, who was dropped from the rotation earlier this week. Pat Light was sent to Pawtucket in the corresponding roster move.

Sean O'Sullivan will start on Sunday against the Angels.

He's getting the call over Aaron Wilkerson. O'Sullivan has posted a 7.94 ERA over three appearances -- two starts -- for the Red Sox this season and should be avoided as a streaming option even against a weak Halos lineup.
Fri, Jul 1, 2016 04:35:00 PM

Sean O'Sullivan was scratched from his scheduled start Thursday for Triple-A Pawtucket.

The Red Sox told their Triple-A affiliate to "stay away" from O'Sullivan on Thursday. The Red Sox need someone to start on Sunday after demoting Eduardo Rodriguez earlier this week. O'Sullivan will likely be considered for Sunday's start, though Aaron Wilkerson is also a possibility. Aside from Steven Wright, Boston's starting rotation has been a mess this year.

Red Sox sent RHP Sean O'Sullivan outright to Triple-A Pawtucket.

O'Sullivan was designated for assignment by the Red Sox on Sunday after allowing six runs -- five earned -- over 4 1/3 innings to the Astros. He had a 7.94 ERA and 1.85 WHIP in 11 1/3 innings with Boston.

Sean O'Sullivan was not long for Sunday's start against the Astros, surrendering six runs (five earned) on five hits over 4 1/3 innings.

O'Sullivan's parting gift for Sunday's horrendous start? The Red Sox designated him assignment. Ouch. He was shellacked for a three-run homer by Luis Valbuena in the second inning, a solo homer by Carlos Correa in the third and a two-run double by Valbuena (yet again) in the fifth before manager John Farrell mercifully pulled the plug. In 11 1/3 innings with the Sox this season, he held a 7.94 ERA, 1.85 WHIP and 7/2 K/BB ratio across 11 1/3 innings. He could pass through waivers without being claimed.

Red Sox designated RHP Sean O'Sullivan for assignment.

No corresponding roster move has been announced yet, but the Red Sox are expected to recall a position player on Monday (possibly Marco Hernandez). O'Sullivan registered a 7.94 ERA, 1.85 WHIP and 7/2 K/BB ratio over his 11 1/3 innings with the big league club. He's likely to pass through waivers unclaimed where he'll continue to function as organizational depth.

Sean O'Sullivan will start against the Astros on Sunday.

O'Sullivan surrendered four runs on 12 hits over six innings in Tuesday's win over the A's. Eduardo Rodriguez (knee) will make at least one more rehab start, affording O'Sullivan an extended look in the rotation. The 28-year-old right-hander is not fantasy relevant.
Wed, May 11, 2016 04:39:00 PM

Sean O'Sullivan was good enough to pick up a win Tuesday, yielding four runs over six frames in a 13-5 victory over the Red Sox.

O'Sullivan didn't walk anyone, but he gave up 12 hits while striking out three. It was far from a tidy outing, which was to be expected, but with the Red Sox blowing the A's out they got what they needed from O'Sullivan. It's unclear whether he'll get another start, but if he does it will be against the Astros this weekend.
