Pennington, 30, hit .406 (13-for-32) with a double, 5 RBI, 6 walks and 5 runs scored in 9 rehab games with Triple-A Reno and Rookie AZL D-backs. In 33 games with Arizona this season, he has hit .243 (18-for-74) with 4 doubles, 1 triple and 6 RBI. He last appeared in a game with the D-backs on June 1 vs. Reds.
Schultz, 28, pitched in 4 games for the D-backs this season, going 0-1 with a 7.88 ERA (7 ER in 8.0 IP). Schultz, who threw 4.1 innings last night vs. Royals, made his Major League debut on March 23 vs. Dodgers in Sydney, Australia.
For Arizona, the move redresses the non-standard set-up of an eight-man Diamondbacks bullpen, which was created on July 29th, when the team sent Alfredo Marte down to Reno and called up Schultz. This was needed due to the heavy workload sustained by the bullpen over the preceding games, which had left it sorely taxed. Schultz hadn't exactly impressed in his second stint, and after working 4.1 innings last night, wouldn't have been able to pitch for a few more days either. With no-one else in the bullpen having had to work since Sunday, our relievers should be recharged enough to be able to cope once more.
