Flu-like bug keeps O's on their toes with pitching

BALTIMORE -- Part of the reason the Orioles did not play a doubleheader Wednesday is that both clubs are still feeling the effects of flu-like symptoms. Rays pitcher Jake Odorizzi was sent home on Monday and the Orioles sent both Evan Meek and Adam Jones home on Tuesday afternoon.

Meek and Jones were back Wednesday, though clearly not 100 percent, and Jones was moved to designated hitter after originally being penciled in at center field.

The Orioles disinfected the whole locker room and shower area Tuesday in hopes of ending this highly contagious bug. Bud Norris was in the bullpen Wednesday, because manager Buck Showalter said a couple more players could be feeling the early stages of the illness.

"They went back over everything again. ... Ping pong paddles, pool sticks," Showalter said of the cleaning. "Everything is a carrier.

"Let's put it this way, I'm glad we didn't schedule a doubleheader for today."

Norris wasn't used on Wednesday, lining him up to start in Boston on Saturday. The Orioles kept Miguel Gonzalez on turn following Tuesday's rainout, pushing Chris Tillman to Friday's series opener following Thursday's off-day.

"Remember when you get something new for Christmas? And your parents were always like, 'Let's keep it new and see what it's like three or four years later.' It's kind of where I am with our pitchers," Showalter said of the decision to give Tillman an extra day and not let Gonzalez get too far removed. "Just thought Tilly could benefit, regardless of who we are facing or where we are down the road. The thing that's optimum is his health. And everybody's."

Jackie gets belated celebration in Baltimore

BALTIMORE -- Following Tuesday's rainout, the Orioles and Rays celebrated Jackie Robinson Day a day late, with both clubs honoring Robinson's legacy in wearing No. 42 for Wednesday afternoon's game at Camden Yards.

The April 15 date honors the anniversary of the former Brooklyn Dodgers infielder's Major League debut and his breaking of the color barrier. Ceremonies all around baseball on Tuesday honored Robinson. Orioles outfielder Adam Jones, who was sent home sick on Tuesday with flu-like symptoms sweeping through the clubhouse, took to his Instagram on Tuesday to show his appreciation for what Robinson has done.

Jones, still not at 100 percent, was able to serve at designated hitter on Wednesday and be part of the belated celebration. He also had "#42" written on his cleats.

"I recognize him every day with how I go out and play the game,"Jones said earlier this week. "Every day, to me, is a tribute to Jackie Robinson and Larry Doby and all the innovators for helping myself, countless other African-Americans, Latins, Asians to play this game. I don't just look at it as one day. I look at that [as] how I treat every single day in the Major Leagues."

Prospects Harvey, Giolito impress in pitchers' duel

In a South Atlantic League pitchers' duel that lived up to expectations Wednesday, the Orioles' No. 4 prospect Hunter Harvey slightly edged the Nationals' No. 1 prospect Lucas Giolito. But both young aces were long gone from the game by the time Delmarva defeated Hagerstown, 1-0, in walk-off fashion in the 15th inning.

Harvey, the Orioles' 2013 first-round pick, struck out seven batters in six shutout innings. The right-hander retired the first seven batters of the game before giving up the lone hit he allowed on the afternoon.

Through three starts this season with Delmarva, Harvey has a 1.06 ERA and an 18-to-4 strikeout-to-walk ratio in 17 innings.

Giolito, the Nationals' 2012 first-round pick, was also in peak form Wednesday. The right-hander allowed two hits in five shutout innings and struck out six.

But even with Harvey and Giolito out of the game, neither team's offense was able to break through for a run until the 15th inning. First baseman Trey Mancini started the winning rally with a two-out single and scored two batters later when third baseman Drew Dosch lined the game-winning hit to left field. Like Harvey, Mancini and Dosch are members of the Orioles' 2013 Draft class.

Worth noting

• There's two or three dates the Orioles are considering for Tuesday's makeup game with the Rays, including a mutual off-day in June. Some of those will have to go through the players' association, Showalter said.

• Kevin Gausman lasted less than four innings in his start for Triple-A Norfolk on Tuesday night, and Showalter said he developed a blister on his pitching hand.

• The grounds crew scraped ice off the field on Wednesday morning, with temperatures in the upper 30s and 40s for game time.
