Taylor Teagarden singled home the tiebreaking run off Aroldis Chapman with two outs in the ninth inning last night, completing the Chicago Cubs' biggest comeback of the season for a 6-5 win and a doubleheader split with the host Cincinnati Reds.

"I knew he was coming after me," said Teagarden, who had only one RBI heading into that at-bat. "I wasn't looking for anything off-speed -- 100 mph, something I could get my barrel on."

The Cubs overcame a five-run deficit to get the split, completed with Teagarden's pinch-hit single off Chapman (3-4).

The Reds won the opener, 9-1, behind another strong showing by righthander Mike Leake (8-5). Todd Frazier extended his post-home run derby surge with three more hits, including a two-run double in the first inning off Kyle Hendricks (4-5).

Dodgers 3, Braves 1: Mike Bolsinger (5-3) pitched seven innings and visiting Los Angeles scored three runs in the fifth. Alberto Callaspo, Jimmy Rollins and Joc Pederson each drove in a run for the Dodgers.

Giants 7, Padres 1: Brandon Belt hit a tying solo home run in the sixth inning and Buster Posey hit a go-ahead, two-run double in the seventh to back Matt Cain (2-1).

Tigers 9, Mariners 4: Nick Castellanos hit a grand slam off the brick facade in left-centerfield, part of an eight-run third inning for host Detroit. Anibal Sanchez (10-7) won his seventh straight decision and Ian Kinsler had four hits for the Tigers.

Astros 4, Red Sox 2: Preston Tucker homered twice and Evan Gattis added a solo shot to back Collin McHugh (11-5) for host Houston.

Phillies 5, Rays 4: Pinch hitter Odubel Herrera's RBI single with two outs in the 10th inning lifted host Philadelphia. The Phillies lost a franchise-record 62 games before the All-Star break but are 5-1 since.

Cardinals 3, White Sox 2: Yadier Molina hit a bases-loaded triple off David Robertson with two out in the eighth inning for visiting St. Louis.

TJ surgery for Vargas?

The Royals have placed lefthander Jason Vargas on the disabled list with a torn ligament in his elbow, an injury that typically requires season-ending Tommy John surgery. Vargas left his start against Pittsburgh on Tuesday night after throwing only 26 pitches. An MRI yesterday that revealed the extent of the injury. -- AP
