The Astros rewarded Pacific Coast League pitcher of the year Brady Rodgers with a September call-up.

The 25-year-old righthander will join the team at Globe Life Park in Arlington on Friday ahead of its series opener against the Texas Rangers, a source confirmed to the Chronicle. Rodgers, a Richmond native and Lamar Consolidated High School product, is expected to pitch out of the bullpen in his first big-league stint.

The Astros' first wave of September call-ups also included first baseman Tyler White and righthanders James Hoyt and Jandel Gustave.

Rodgers, the Astros' third-round draft pick in 2012, broke out this season with a 2.86 ERA over 22 starts spanning a career-high 132 innings. He struck out 116 opposed to 23 walks, improving in both categories from his first season in Class AAA (4.51 ERA in 21 starts).

Rodgers' fastball sits only 89 to 90 mph, so his success is reliant on command and effectively mixing his pitches. In addition to a slider he revamped in spring training with the help of Astros set-up man Luke Gregerson and pitching coach Brent Strom, Rodgers features a cutter, a curveball and a changeup.

The Astros added Rodgers to the 40-man roster, on which they had one open spot. They planned to roster the pitcher in the offseason anyway to protect him from December's Rule 5 draft, in which he went unselected last year.
