Former A's reliever Johnson works out for O's

WASHINGTON -- There are plenty of reasons why Orioles manager Buck Showalter would like Jim Johnson to return to the club. With several teams showing interest in him, Johnson may have more reasons not to make a Baltimore homecoming.

The relief pitcher, who was formally released by the Athletics on Friday, worked out for the O's in Sarasota, Fla., on Monday and spoke to Showalter later in the day.

Showalter said that he and vice president of baseball operations Dan Duquette "have painted the picture very bluntly" to Johnson about a potential role within the organization. With the Orioles' bullpen pitching well, there's not an immediate need for Johnson on the big league roster.

"He's got to make the decision. He's earned that right," Showalter said. "People are wanting his services. We'll see. He's very respectful of our situation here and how well our guys are pitching in the bullpen, too. You can never have too many."

Johnson threw for Minor League pitching rehab coordinator Scott McGregor and coordinator of medical services Dave Walker in Sarasota, where Johnson has a home, before he went to work out at another facility.

There's nothing imminent between Baltimore and Johnson, but Showalter expects his former closer to make a decision about his future "sooner rather than later."

The O's dealt Johnson to Oakland during the offseason in exchange for infielder Jemile Weeks and catcher David Freitas. Johnson began the season as the A's closer, and after allowing five runs in his first two outings -- a total of one inning -- he was dropped from the role.

When the Athletics designated him for assignment on July 24, Johnson had a 7.14 ERA and two saves.

"I think the mistake you make is thinking that you've got some magic dust that you sprinkle on him," Showalter said. "There are some very capable people in Oakland, Jimmy being one of them, but I know [pitching coach] Curt Young, I know [manager] Bobby Melvin -- they're really good at what they do. Jimmy's got some work cut out for him, but he's certainly got a good pedigree and a history of having success.

"He's got a tough decision to make, but a good one. He's got people interested in him."

Ubaldo likely to return to O's rotation this week

WASHINGTON -- Ubaldo Jimenez feels good after making his second rehab start and expects to return to the Orioles later this week.

The starting pitcher, who has been on the disabled list since July 13 with a right ankle injury, threw 94 pitches for Triple-A Norfolk on Sunday and allowed one run on five hits and two walks with three strikeouts.

"He got his work in, got his pitch count up," Orioles manager Buck Showalter said. "Not a lot better [than last time], just better, which you expected."

Jimenez will travel with the O's to Toronto for their three-game series with the Blue Jays that begins on Tuesday and could be activated any time after Thursday.

The Orioles haven't officially announced any starters past Thursday. Chris Tillman would be slotted for Friday if Baltimore stays on schedule with its current five-man rotation. Jimenez could pitch on Friday on regular rest as well, although he could get some extra rest ahead of his first Major League start in more than month.

"[We'll] see how he feels tomorrow with it, take his work day when he needs to and we'll see how it slots out after Thursday," Showalter said.

Neither Showalter nor Jimenez envisions a scenario with Jimenez in the bullpen, but the O's starters have been excellent in Jimenez's absence. Since June 10, Orioles starting pitchers rank sixth in the Majors with a 3.13 ERA.

Jimenez, who signed a four-year contract for $50 million this offseason, is 3-8 with a 4.52 ERA and leads the American League with 60 walks this season. Last season, Jimenez posted 1.82 ERA in the second half after struggling to a 4.56 mark before the All-Star break.

"I wouldn't call it a problem to have a good situation," Showalter said of his apparent pitching surplus.
