Reds right fielder Jay Bruce entered Sunday on one of his patented Jay Bruce hot streaks. The streak sort of continued, as the game featured both Bruce extremes.

Bruce hit a three-run homer for the Reds' only runs in a 7-3 loss to San Diego, but he also struck out three times.

"It's one of those things, you guys have seen it," Bruce told reporters. "When I'm good, I'm good. When I'm not, I'm usually not."

Bruce entered the day with four consecutive two-hit games, but his only hit Sunday was his homer. Bruce now has homered in three straight games and four of his last five.

Entering Sunday, Bruce for the past week was leading the majors in RBI (12), slugging percentage (1.143) and runs scored (eight).

The streakiness both thrills and irritates Reds fans, with Bruce seemingly either scorching hot or ice cold. Bruce was NL Player of the Month in May, when he had 12 homers, 33 RBI and hit .342. Bruce then totaled only five homers and 19 RBI for June and July, while hitting just .236.

"One of the things I've always been trying to get is more consistency, and it's something I think comes with experience," Bruce said. "As I get older, I'll learn what it takes to minimize those funks."
