"I felt really good," Lewis said. "I stunk, that's about it. I walked five guys, that's uncalled for. This one is definitely on my back."
Lewis was sidelined from June 22 to Sept. 10 with a strained lat in the back of his right shoulder. In his first start back against the Angels, he allowed three runs on seven hits and two walks in 5 1/3 innings. This time he allowed just three hits, but walked five.
Lewis said he can't remember the last time he walked five batters in a game. In fact, it has happened just three times in 159 starts for the Rangers over the past six years. The last time was Sept. 25, 2014, against the Athletics.
"I hold myself responsible," Lewis said. "I hold myself to a higher level. At this stage of my career, I shouldn't be doing this."
Lewis took a 2-1 lead into the sixth. At that point he had allowed two hits, including a fourth-inning home run to Khris Davis, and two walks while striking out four.
That was it for Lewis, who left the game having thrown 92 pitches, including 48 for strikes.
"The challenge for me was just over 50 percent of his pitches were strikes," manager Jeff Banister said. "He was erratic with his fastball on the edge. The five walks were a bit of a challenge for us. We know his body of work, he is a strike thrower. These guys made him work and didn't chase. I chalk this up to a guy working his way back."
Lewis did not.
"It doesn't matter," Lewis said. "I'm in the big leagues. I've got a responsibility no matter what the situation. I'm not putting it on anything, on my second start. … I didn't do my job. I didn't do what I have to do in the sixth inning. That's it."
Alex Claudio took over and pinch-hitter Renato Nunez hit a chopper to second baseman Rougned Odor, who had to settle for a force at second as the go-ahead run came across. Claudio got the Rangers out of the inning by getting Brett Eibner on a grounder to second, but the damage was done.
"If I did my job, it's a different course," Lewis said.
