4.65 ERA in 2012. He began the season well, going 5–1 and 3.12 through May 21, but as Houston's season went rapidly downhill so did Norris'. He proceeded to go 0–12 with a 6.34 ERA during a streak of 18 starts while he battled injuries and inconsistencies. He finally ended the streak of futility on September 26 with a scoreless start on his way to a win at home against the St. Louis Cardinals and wrapped up his season with another scoreless effort and win at Wrigley Field against the Chicago Cubs. He was the last pitcher to bat at Minute Maid Park prior to the Astros' transfer to the American League for the 2013 season. Just before the deadline for clubs and players to exchange numbers for arbitration on January 18, 2013, Norris agreed to $3 million for the 2013 season. Baltimore Orioles Norris was traded to the Baltimore Orioles on July 31, 2013 for L. J. Hoes and minor league pitcher Josh Hader. On the day after the trade, the Astros were already in Baltimore playing the Orioles, so Norris switched dugouts and won the game. Norris was ejected on May 12, 2014, when he hit Detroit Tigers outfielder Torii Hunter in the ribs with a pitch at Camden Yards, prompting both the Orioles' and Tigers' benches and bullpens to clear. Norris had also had run-ins earlier in the season with Boston Red Sox catcher David Ross and Pittsburgh Pirates infielder Neil Walker, but the Hunter incident resulted in his first major-league ejection. At the time of his ejection, Norris was tied for second in the American League (AL) with 5 hit batters in 43 innings, an average of 1 hit batter every 8.6 innings. In his prior career spanning 740 innings pitched since 2009, Norris had hit only 27 batters, an average of one every 27.4 innings. On January 26, 2015, Norris and the Orioles agreed to a $8.8 million contract. He would get a $25,000 bonus for 180 innings and $50,000 more for 200 under Monday's agreement. Norris also would earn $50,000 each for making the All-Star Game or winning a Gold Glove. Norris was designated for assignment on July 31, and released on August 8.
