The homer was more celebratory than critical after Morton handcuffed the Brewers to end years of futility against Pittsburgh's biggest nemesis. Milwaukee has won more than 70 percent of its games against Pittsburgh since 2007 and came in 4-0 against Morton.
That run of dominance is now over. Morton, still finding his way back from Tommy John surgery, dominated after some early trouble. The Brewers put four runners on base in the first inning but couldn't score and Morton took care of matters from there. He retired nine straight at one point and would have worked deeper if not for a rare mental mistake by catcher Russell Martin.
Leading by four in the seventh, Martin tried to pick Yuniesky Betancourt off first. The ball sailed into right field, allowing Scooter Gennett to score.
Byrd's long ball restored order and the Pirates exhaled while clinching the season series against the Brewers for the first time since 2006.
NOTES: Pirates LHP Wandy Rodriguez continues to deal with left forearm inflammation but will not require surgery. Rodriguez, who has been on the disabled list since May, was evaluated by Dr. James Andrews in Florida on Tuesday after experiencing discomfort during a throwing session. Rodriguez will resume throwing later this week ... Brewers prospect Johnny Hellweg was named the Pacific Coast League Pitcher of the Year. Hellweg is 11-5 with a 3.16 ERA for Triple-A Nashville. The right-hander, who is 0-3 with a 10.97 in three starts with Milwaukee this season, will be recalled to the majors next month ... The series concludes on Thursday when Pittsburgh's Gerrit Cole 6-6, 3.81 ERA) faces Milwaukee's Yovani Gallardo (9-9, 4.61).
