Guilmet sent down to make room for Gonzalez

ANAHEIM -- Miguel Gonzalez was recalled from Triple-A Norfolk to start Tuesday's game against the Angels, with reliever Preston Guilmet optioned to Triple-A to clear a roster spot.

Gonzalez was optioned to Triple-A prior to the All-Star break to stay on track and to allow the O's to add another person to the roster during that time. He is coming off back-to-back eight-inning outings.

Guilmet, 26, has posted a 5.23 ERA and 12 strikeouts in 10 appearances for the Orioles this season.

Machado day to day with back tightness

ANAHEIM -- Manny Machado was a last-minute scratch from Tuesday's Orioles starting lineup with back spasms and the 22-year-old is day to day.

Machado first felt the issue creep up during his last round of pregame batting practice at Angel Stadium and after getting treatment, he was hopeful he'd still be able to suit up.

"It took a lot for me," said Machado, who has no history of back issues. "I was out there, and tried running more sprints to see if it was going to go away. But it kept getting tighter and tighter. I really didn't want to, but it was best for the team. In the situation I was at, I wasn't going to be able to be an elite player and help the team win. It was a better situation for me and the team."

Machado was replaced at third base by Ryan Flaherty, who moved down to the eighth spot in the batting order. Second baseman Jonathan Schoop moved up from ninth to Machado's original spot at seventh, with catcher Caleb Joseph moving down to hit last.

"[Machado] walked over to me and said, 'Skip, I don't think I can go.' and I looked and said, 'Are you serious?' We were ready to take out the lineup card," said manager Buck Showalter, who debated on moving first baseman Chris Davis over to third to keep Steve Pearce starting. "Talk about pressure to come up with a lineup."

While Showalter should have more time on Wednesday, it's unclear whether Machado will be back after just a one-day reprieve.

"We saw a doctor and he said it just spasm'ed up a little bit," said Machado, who had no plans Tuesday for an X-ray or MRI. "Took some pills and hopefully it gets better with some time. We'll see how it feels tomorrow."

Added Showalter: "I'll feel a whole lot better [Wednesday] if it manages itself. It's the old day to day."

Machado has played in 66 games for Baltimore this season, missing the first month recovering from offseason knee surgery and recently serving a five-game suspension. He also missed a couple games with a right groin injury in May.

Machado entered the day batting .267 with 10 homers and 23 RBIs.

Rebounding Bundy records best outing of season

ANAHEIM -- Orioles top pitching prospect Dylan Bundy turned in his best outing of the season on Tuesday, tossing six scoreless innings for Class A Advanced Frederick.

Bundy, who picked up the win, went a season-high six innings and was able to stay under his 75-pitch limit, which will hold for all of his outings this year coming off Tommy John surgery. The right-hander faced 22 batters and allowed three hits and two walks while picking up a strikeout.

Former Orioles pitch coach "Mark Connor texted me. He's at Myrtle Beach with the Rangers. ... He was watching Bundy's outing," Orioles manager Buck Showalter said. "He was doing real well through the fifth, started elevating the ball after that."

Bundy has made four starts for Frederick and is 1-1 with a 6.11 ERA. Showalter has said previously that he expected Bundy to struggle initially when he was moved up from Short-Season Aberdeen before finding his footing. The Orioles have not ruled out Bundy helping the big league club this season, although given his pitch count restrictions, it's unlikely.

Jimenez's ankle injury slow to mend

ANAHEIM -- Ubaldo Jimenez is progressing slowly from a right ankle injury and manager Buck Showalter said Tuesday there's a possibility Jimenez goes back to Baltimore or is sent to the team's spring facility in Sarasota, Fla.

"It's getting a little better each day, but it's been quite a while," Showalter said of Jimenez, whose DL stay started on July 8.

Jimenez is slated to throw his second bullpen session on Wednesday, with the team opting to give him an extra day. He was favoring his ankle too much in his last 'pen session to go out on a rehab assignment and the hope is he'll do much better in his next throwing session.

"Let's get through Wednesday and we will all sit back and step back and say what's the [plan]," Showalter said. "It may be he continues with us to Seattle. I'm hoping he gets a little better."

Jones honored for his 'Heart & Hustle'

ANAHEIM -- The Major League Baseball Players Alumni Association announced Tuesday that Adam Jones has been named the Orioles 2014 Heart & Hustle Award winner.

The award honors active players who demonstrate a passion for the game of baseball and best embody the values, spirit and tradition of the game. The Heart & Hustle Award is also the only award in Major League Baseball that is voted on by former players.

"A couple years ago I remember Buck [Showalter] getting on my tail for not giving 110 percent, and it's made me give 150 now," Jones said.

"I appreciate [the award]. Just want to do my part to help the team. I'm glad to see that people see that, not just myself but my team, we go out there every single day and give it our all."

"He represents all the best qualities of a teammate and competitor," said Brooks Robinson, Orioles Hall of Fame third baseman and Major League Baseball Players Alumni Association president in a press release. "The way he plays the game sets an example for young players to follow."

The MLBPAA formed 30 committees, comprised of alumni players with established relationships to each team. One player from each Major League team is chosen by the committees based on their passion, desire and work ethic demonstrated both on and off the field. These players will be recognized prior to an upcoming home game. As the season draws to a close, fans, all alumni and active players will vote to select the final winner from the 30 team winners. The previous overall winners are David Eckstein (2005), Craig Biggio (2006, 2007), Grady Sizemore (2008), Albert Pujols (2009), Roy Halladay (2010), Torii Hunter (2011), Mike Trout (2012) and Dustin Pedroia (2013).

The final winner will be announced on November 18,2014 at the 15th Annual Legends for Youth Dinner in New York City. This event is the primary fundraiser for the series of free Legends for Youth Baseball Clinics. These clinics impact more than 15,000 children each year at 110 clinics, allowing them the unique opportunity to interact with and learn from players who have left a lasting impact on the game of baseball.
