Markakis swung at the first pitch he saw from Toronto ace Roy Halladay with one out in the frame, firing it into right field for a base hit. The 25-year-old has gotten at least one hit or walk in every game since July 5 in Anaheim.
Going into Sunday's game, Markakis was hitting .306 with a .364 on-base percentage over that span. Markakis, who was batting .299 with a .354 OBP on the season entering the game, has reached base in 96 of his 110 starts.
While Markakis' streak currently leads the big leagues, it's only the second-longest run of his career. The right fielder reached base in 35 straight games from late in the 2008 season through May 5.
"He's consistent, and he's consistent in all areas of the game," Orioles manager Dave Trembley said. "He kind of can go unnoticed if you don't have the privilege to watch him day in and day out, because he just goes about his business as a big leaguer.
"I think he has to be one of the best right fielders in the game. He's the total package and a very good player."
