Worth noting

• Jake Arrieta threw a bullpen session for Triple-A Norfolk on Tuesday, and once he started throwing, he didn't have any right shoulder discomfort. Showalter said he wasn't sure if Arrieta, who missed Sunday's scheduled start, would pitch for Norfolk this weekend or not.

• Had the Orioles tied the game on Tuesday night, Showalter said Chris Davis -- who was pinch-run for -- would have been replaced at first base by Nick Markakis.

• Three Orioles have 13 or more doubles -- Adam Jones, Manny Machado and Davis -- the most of any Major League club. Machado hit three more in Wednesday's 8-4 loss to San Diego to up his season total to 17, Davis hit one and now has 14 on the year.

• Machado went 1-for-4 in Tuesday's loss to the Padres, but that ended his streak of three-hit games at three. Machado was the first Orioles player to do accomplish that feat since Melvin Mora in 2008. But he stayed hot on Wednesday, tying his career high with four hits.

According to Elias, the last Major League player under the age of 21 to have three straight three hit games was Pittsburgh's Rennie Stennett (Sept. 3-5, 1971).

The Orioles have had just three players get three hits in four straight games -- as Machado tried to do Tuesday -- Don Buford (1970), Eddie Murray ('81) and Cal Ripken, Jr. ('90).

Machado is hitting .343. He has 12 career homers and, according to STATS, if Machado can get one more homer before July 6, he'll pass Boog Powell for the most home runs by an Orioles player before the age of 21.
