The Phillies called up outfielder Greg Golson and lefthander Josh Outman to Double-A Reading Thursday, adding some prospect bulk to the R-Phils’ roster.

Golson, the 21st overall pick in 2004, has scuffled over his first two full seasons, compiling 266 strikeouts and in 921 at-bats heading into this year at high Class A Clearwater. And while Golson will likely top his career-high 160 strikeouts from last year, he is showing more of what the Phillies expected out of him than ever before–hitting for average with some emerging power to go along with some of the best speed in the system.

In 416 at-bats in the Florida State League this year, Golson batted .286/.324/.452 with 12 homers, 52 RBIs and 25 steals in 33 attempts.

“He’s grown up a lot, and we still have to remember this kid’s just 21 years old,” Phillies farm director Steve Noworyta said. “What he did (in the FSL) is pretty darned impressive. I think he wanted to be a little further along the path than he is, but we’ve been patient and he’s come around nicely.”

Outman, a 10th rounder in 2005 out of Central Missouri State, went 10-4, 2.45 with 117 strikeouts in as many innings for the Threshers. The 22-year-old’s fastball has sat in the 90-94 mph range with improved tilt on his slider and his changeup has improved to an above-average pitch.
