Gleaned from wire reports, all emphasis mine:

Reds rookie Homer Bailey looked like he belonged in the big leagues during his five innings, allowing only one run. The 21-year-old pitcher looked like an overmatched rookie in his last two times out, giving up 13 runs, 13 hits and eight walks in only 5 1-3 innings of resounding losses.

After the last pounding, he watched video of his performance and detected a small flaw in his delivery. With the problem fixed, he looked like a top prospect again.

With their rare rally, the Reds improved to 4-1 under interim manager Pete Mackanin.  They've won back-to-back series for the first time since they opened the season by going 4-2 against the Cubs and Pirates.

A sprained wrist forced Cincinnati Reds outfielder Josh Hamilton to leave for a pinch-hitter in the third inning of a game against Arizona on Saturday night.

Hamilton hit a grounder to Stephen Drew in the first inning, reaching safely on the shortstop's fielding error. He winced after he crossed the base but stayed in the game.

When it came time to bat again, he headed for the trainer's room instead. The Reds said he'd have a cast put on the wrist, and it will be examined again during the All-Star break.

Also, from The Blog That Shall Not Be Named:

Mackanin said he'd like to try to get Valentin about three starts a week behind the plate. Javy said his defense and confidence was hurt when Jerry Narron said he wasn't going to use him much as a catcher. He said now he feels like he's back at spring training. He was out before the game working and has been doing extra workouts before the game since Monday.

Josh Hamilton left the game with a sprained right wrist suffered while swinging a bat in the on-deck circle. He will wear a cast until Thursday, when he will be examined in New York by Kremchek.
