"We felt like he has gotten to the point of the season where we are moving into the All-Star break," Banister said. "If we can limit him an inning here or there, the benefit is we need this guy as strong as possible and have him fresh throughout the season and down the stretch."
Hamels is 4-0 with a 0.65 ERA in his last four starts, and he has been under 100 pitches in his last three outings. He is fifth in the American League with 103 2/3 innings and ninth in the league with an average of 102.1 pitches per game.
"If there is an opportunity where we don't have to push him an extra inning, it would be nice," Banister said. "The benefit is to keep him fresh the whole year."
Surkamp adds starting depth
The Rangers added more starting depth when they claimed left-handed pitcher Eric Surkamp off waivers from the Athletics. Rangers general manager Jon Daniels said Surkamp will be used as a starter with Triple-A Round Rock.
Surkamp has done both in parts of five Major League seasons with the Giants, White Sox, Dodgers and Athletics. He is 2-8 with a 7.15 ERA in 16 career starts and 2-0 with a 5.53 ERA in 36 relief appearances.
"We like the guy, we like the arm," Banister said. "He's obviously an experienced guy who adds depth."
Surkamp was 0-5 with a 6.98 ERA in nine starts for the Athletics and 3-1 with a 3.07 ERA in five starts at Triple-A Nashville.
