Weeks makes immediate impact with O's

BALTIMORE -- Jemile Weeks was penciled into the leadoff spot as the designated hitter for the second straight game on Sunday after being recalled from Triple-A Norfolk.

Weeks went 2-for-4 with a triple and a run scored in Saturday's 3-2 walk-off victory in 10 innings over the Royals. He started a two-run rally in the first inning with a leadoff single off of Jeremy Guthrie.

Weeks also laid down a sacrifice bunt in the 10th inning and reached on pitcher Danny Duffy's second throwing error of that frame, which set up Nick Markakis' walk-off single. Weeks wound up having a hand in both of the team's scoring rallies.

Manager Buck Showalter said second base is the best position for Weeks, who also could help out in the outfield. Plus, he has plenty of speed and some power.

"Jemile has some versatility," Showalter said. "I know from trying to defend him in the past, he's got a little more pop than people think he does. He makes people hurry in the infield."

The Orioles acquired Weeks in trade with Oakland for Jim Johnson during the offseason. Weeks didn't make the club out of Spring Training, and Saturday was his Baltimore debut.

In Sunday's 9-3 loss to the Royals, Weeks went 1-for-4 and scored on Nelson Cruz's two-run homer.

Machado goes 4-for-4 in third rehab contest

BALTIMORE -- Orioles third baseman Manny Machado went 4-for-4 with three runs scored, two RBIs and one walk on Sunday in his third rehab appearance for Class A Advanced Frederick.

Machado also played in games on Friday and Saturday -- going a combined 4-for-8 with three extra-base hits. He's now 8-for-12 overall and has played two games in the field at third base plus one as the designated hitter.

"We'll see where we are at the end of [Sunday]," Orioles manager Buck Showalter said prior to the Orioles' 9-3 loss to the Royals. "I think the biggest part of that equation is what Manny thinks. We're a lot closer than we were."

Showalter said Machado will likely be the DH at Frederick again on Monday.

"Who knows? Manny might be another four or five days, six days [or] a week," Showalter said. "I don't think it's fair to say it's going to be in this realm. It's not fair to Manny, [and] it has nothing to do with the Chris Davis move, in my mind."

Worth noting

Nick Markakis was in the starting lineup at first base on Sunday for the second straight day following the Chris Davis injury. Markakis, who went 1-for-3 and scored on a wild pitch in a 9-3 loss to the Royals, made his fifth career appearance at first and fourth start at the position.

• Showalter said Bud Norris was fine after a side session on Sunday and will make his scheduled start on Wednesday against the Pirates. The skipper also said they are going to take a look at everything on Tuesday before announcing the rotation order for next weekend's series with the Twins. Norris was testing his right hamstring, which bothered him during his start in Toronto.

• Pitcher Johan Santana will pitch in a simulated game on Monday in Sarasota, Fla. He's slated to throw three innings or 45 pitches.
