So can Jake Arrieta pitch more often than once every five days? Probably not. But the 24-year-old rookie right-hander is now 2-0, 2.77 after two Major League starts. Pitching vs. a Giants team that had won four in a row and had scored 10 runs the night before, Arrieta gave up just three hits and one run over seven innings and one batter on Tuesday night. He walked two, fanned three and threw 95 pitches. Here is a pretty remarkable stat. O's starting pitchers have just two wins over the last 19 games and they are the two starts by Arrieta. Just like vs. the Yankees, he looked composed at the start and retired the side in order in the first. He gave up a Pablo Sandoval homer in the third inning and that was the only hit he allowed over the first five innings. He did this vs. a Giants team that had scored six runs or more in nine of their last 16 games. David Hernandez pitched the ninth to get his second save. One of his fastballs registered 99 on the radar gun. Adam Jones hit a solo homer, Miguel Tejada had three hits and Ty Wigginton drove in a pair for the Orioles. The Birds ended a four-game losing streak and a nine-game road losing streak. They can win the series in San Fran if they can win Wednesday afternoon vs. Tim Lincecum. O's pitching: Previous two games: allow 21 runs on 27 hits. Tonight vs. SF: allow one run on three hits. O's starting pitching: Previous two games: 7 1/3 IP, 14ER, 17H, 4 HR. Tonight vs. Giants: 7 IP, 1ER, 3H, 1 HR. Hitting notes from the win: *Nick Markakis had two doubles Tuesday.
