1) “American Ninja Warrior” (shown here), 8-10 p.m., NBC. The semi-finals begin. In five weeks of qualifiers, only seven people conquered the “Mega Wall.” Now they – and others – move on; they’ll face up to 10 obstacles, including the new Kaleidoscope, Ghost Town and Spin Zone.
2) All-Star preview, ESPN. On Tuesday, baseball’s best will collide in Dodger Stadium, for the All-Star Game. ESPN surrounds that with events – the Espy awards Wednesday (on ABC) and other things today. It starts its “Baseball Today” and “Sports Center” marathon at 4 p.m., then shows the Home Run Derby (an annual All-Star lead-in) at 8. At 10, it has the opener of “The Captain,” a seven-part documentary on Yankee great Derek Jeter.
3) “Better Call Saul,” 9 p.m., AMC, rerunning at 10:20. This was ideal timing: Last Monday, “Saul” returned from a break, to start the final six episodes of its final season. The next day, it got Emmy nominations for best drama series and for its stars, Bob Odenkirk and Rhea Seehorn. Last week, those two were held at gunpoint, as a crafty (but failed) diversion, in an attempt to kill Gustavo. Now they’re supposed to act like nothing happened.
4) “Bob (Hearts) Abishola,” 8:30 p.m., CBS. On a show that usually thrives on understated wit, this was one of the more offbeat episodes. Abishola’s mother has clearly overstayed her welcome. Now there’s a scheme to fake a séance, with a message from the grave.
5) “In the Dark,” 9 p.m., CW. This wraps a two-parter, with Murphy – the show’s protagonist, who is blind – is on trial. That’s preceded at 8 by “Roswell, New Mexico”: While Kyle and Isobel face fall-out for their actions, Liz wants scientific answers and Bonnie wants Max, the cop, to protect her.
