Every lineup, every day, as they are made public by the clubs.

The Blue Jays activated outfielder Kevin Pillar from the 15-day disabled list prior to Tuesday’s series opener against the Angels.

Matt Duffy and Brad Miller have transitioned well to their new positions since the pair changed the complexion of the Rays’ infield.

Orioles right-hander Chris Tillman “did not have a good work day” on Tuesday, manager Buck Showalter said, and his start Thursday at Washington is in jeopardy. Showalter said Tillman would have his right shoulder examined before Tuesday’s game by Dr. Leigh Ann Curl. Showalter plans to make a decision on Thursday’s start on Wednesday.

The Mariners activated right-handed reliever Tony Zych from the 60-day disabled list Tuesday to fill the hole in their bullpen, and they optioned infielder/outfielder Stefen Romero to Triple-A Tacoma.

The 112th World Series on FOX will begin on Tuesday, Oct. 25, in an AL city to be determined.

That’s a pretty great day.

In the first inning of the Orioles’ 15-8 loss to the Astros last Friday, No. 2 hitter Hyun Soo Kim stood at first base with no outs following a single. For some teams, the situation might stir thoughts of a stolen base, which would move the runner into scoring position and take away the defense’s chance for a double play.
