ON DECK

A look at what’s happening all around the majors today:

A VIEW FROM THE TOP: The Cleveland Indians open a four-game series at Texas, with Josh Tomlin (11-7, 4.39 ERA) facing Rangers lefty Cole Hamels (13-4, 2.80). Both clubs lead their division — the last time these teams met so late in a season with both in first place was 1999.

DODGER DADDY: Rob Segedin is expected to return to the Dodgers for a game against San Francisco following a one-day paternity leave and a wild start to the week. The rookie hit his first major league homer on Monday in Cincinnati, then homered off Giants ace Madison Bumgarner on Tuesday before leaving in the eighth inning and rushing to the hospital to meet his wife, Robin, for the birth of their first child. Manager Dave Roberts had to convince Segedin to take the one day of paternity leave.

EMERGING ACE: Blue Jays left-hander J.A. Happ (17-3, 3.05) goes for his 18th win in a game against the Angels. Happ is 11-0 with a 2.53 ERA in his past 12 starts.

HEALED UP: Mariners lefty James Paxton (4-5, 3.53) is expected to come off the disabled list to pitch the opener of a series against the White Sox. Paxton took a line drive off his pitching elbow Aug. 7 and has been out since.

LUCKY MOUND: Orioles righty Ubaldo Jimenez will get his first start since July 28, facing NL East-leading Washington. He’ll pitch in place of ace Chris Tillman, who was put on the 15-day disabled list with bursitis in his shoulder.
