Monday's MLB roundup

One moment, Bryce Harper was getting ejected from the dugout. The next, teammate Clint Robinson was hitting a walk-off homer.

And seconds after that, Harper was rushing onto the field — to join the rest of the Washington Nationals in celebrating a dramatic 5-4 victory over the Detroit Tigers, yes, but also to scream what he acknowledged were "a couple choice words" at the umpire who tossed him in ninth inning Monday night.

Told that TV cameras captured him cursing in the direction of umpire Brian Knight after Robinson's one-out drive off Mark Lowe, Harper replied: "Absolutely. I was pretty upset. … So let him hear what I have to say — and let him hear it again. And, you know, so what?"

Asked whether he expects to be fined, Harper said: "If I do, I do. I'll pay it. Maybe he'll get fined, too. So we'll see."

He was ejected after Danny Espinosa struck out looking. "Everybody was up on the steps and preaching about what they thought was going on," Harper said. "And [Knight] picked me and said, 'See you later.' "

Manager Dusty Baker went out to argue with Knight after the ejection. Afterward, Baker said the umpire told him he had considered kicking out Harper earlier in the game.

Once play resumed, Robinson connected with the second pitch he saw. Robinson did not realize what was at stake: He had lost track of the inning and was sure it was the eighth.

Not until he touched third base did Robinson figure out what had happened, that he had ended Washington's four-game losing streak and extended Detroit's skid to seven.

"Everything's not going our way," said Tigers manager Brad Ausmus, whose team blew a 4-1 lead. "It'll change."

Chicago 8, Texas 4 (12): Todd Frazier hit a tiebreaking grand slam in the 12th inning for his second homer of the game, powering the White Sox over the host Rangers.

Frazier had four hits and a career-high six RBI to help the White Sox win after the bullpen blew leads in the eighth and ninth innings.

Last year's All-Star Home Run Derby winner in front of the home crowd in Cincinnati, Frazier has 10 homers with Chicago after an offseason trade. His go-ahead blast to left came off lefthander Cesar Ramos.

New York 6, Kansas City 3: Carlos Beltran hit two of host New York's five solo homers in the first three innings off Chris Young, and Aroldis Chapman gave up a run in his Yankees debut before closing out the slumping Royals.

Chapman, a four-time All-Star with a fastball that often exceeds 100 miles per hour, was eligible to pitch for the first time with the Yankees after serving a 29-game suspension under baseball's new domestic violence policy. The lefthander from Cuba was obtained from Cincinnati in December.

Brian McCann, Brett Gardner and Aaron Hicks also went deep to help New York win the opener of a four-game set vs. the World Series champion Royals, who have lost 10 of 13.

Boston 14, Oakland 7: Jackie Bradley Jr. hit a grand slam and drove in six runs, and the host Red Sox overcame a four-run deficit against Sonny Gray to blow out the Athletics.

Houston 7, Cleveland 1: Jose Altuve drove in three runs and the host Astros chased Indians ace Corey Kluber during a five-run third inning.
