McFarland activated from bereavement list

BALTIMORE -- After spending three days on the bereavement list and missing the first two games of the Orioles' series with the Angels, T.J. McFarland was activated on Thursday and was available to pitch in the series finale.

Relief pitcher Preston Guilmet was optioned to Triple-A Norfolk.

McFarland, who has appeared in 23 games this season and started one, is 4-2 with a 3.07 ERA, 23 strikeouts and 11 walks this season. The lefty has served as the O's primary long reliever this season, giving the Orioles 10 multi-inning relief appearances.

Since the start of June, McFarland has a 2.10 ERA, 16 strikeouts and six walks.

Guilmet didn't pitch during his latest stint in the Majors -- his fifth time on the 25-man roster this season.

"I love being the guy that they know they can rely on me," Guilmet said. "I just take the opportunities when I get them and make the best of them."

McFarland's return to the active roster may not last long. Baltimore added relief pitcher Andrew Miller in a trade with the Red Sox on Thursday and he is expected to report by Friday's series opener against the Mariners. At that point, the O's will option a relief pitcher.

Brad Brach and Ryan Webb are also candidates to be optioned.

Davis comes off bench after bout with illness

BALTIMORE -- When Buck Showalter was drawing up Thursday's lineup card for the series finale against the Angels, Chris Davis was an option. The first baseman, who had missed the past two games due to an illness, was back with the team and an option to make his return to the starting lineup.

When it finally came to it, though, the manager opted to take caution. Davis was available, but wasn't on the field to start the game. But he did finish it, entering in the ninth inning as a pinch-hitter to replace Delmon Young. Davis stuck out and walked in two plate appearances.

"Chris was moving around with his gloves on from about the seventh inning on," Showalter said of Davis, who remained in the game as the designated hitter. "He was ready to get that out of the way. I asked him how he felt, coming down here. He said, 'All things considered, OK."

Davis had battled nausea and a fever since Monday and was sent home from Camden Yards early on Tuesday. He made it to the stadium for the end of Wednesday's game and was ready to resume baseball activities on Thursday.

Davis declined to elaborate on his illness, although he doesn't seem to worried about his recovery.

"I'm here, I'm healthy, I'm not in the lineup," Davis said.

Worth noting

• Starting pitcher Ubaldo Jimenez will make another rehab start on either Sunday or Monday for Triple-A Norfolk before returning to the Orioles.

• A win on Thursday would have given Baltimore its first three-game sweep of the Angels since 2010.
