A rundown of games and events to watch for locally and nationally from the world of sports (all times Pacific):


Running, 2019 Boston Marathon, 5:30 a.m. (NBCSN): More than four hours of TV coverage is planned for the 123rd edition of the world’s most famous marathon. This year’s race is the first that will take place on the actual anniversary of the deadly bombing in 2013. The city of Boston has declared April 15 as One Boston Day to honor the memories of those killed and injured six years ago.


NBA basketball, Oklahoma City at Portland, 7:30 p.m. (TNT, NBC Sports Northwest): Sunday’s Game 1 win was the first for the Blazers over the Thunder after dropping all four regular-season meetings. It also helped erase the memory of being swept by New Orleans in the first round last year. Games 3 and 4 in the best-of-seven series are set for Friday and Sunday nights in Oklahoma City.


NHL hockey, San Jose at Vegas, 7:30 p.m. (NBCSN): After dropping the opening game of this spirited first-round Western Conference playoff series, the second-year Golden Knights bounced back to win two straight and can take a commanding lead in the best-of-seven series with a home win in Game 4. Vegas eliminated the Sharks in the second round last season.


Major League Baseball, Cleveland at Seattle, 3:40 p.m. (Root): From out of nowhere, the Mariners got off to the best start in the majors and close out a three-game series against the reigning AL Central champions at T-Mobile Park. Could the M’s be on their way to the playoffs for the first time since 2001, and thus end the longest current postseason drought in American professional sports?


Prep track and field, Summit Invitational in Bend, 10 a.m.: Many of Central Oregon’s finest runners, hurdlers, jumpers and throwers will be showcased in this midseason measuring-stick meet at Summit High School. In addition to the host Storm, area teams expected for the meet include Bend High, Mountain View, Redmond, Ridgeview, La Pine and Madras.
