The odds were against the Milwaukee Brewers as they had to call up Eric Lauer from the alternate training site to make the start against the World Series champions Los Angeles Dodgers, but they prevailed 2-1.
Lauer entered the game with a 14-19 record in the majors but out-pitched last year's Cy Young Award winner Trevor Bauer in Milwaukee, scattering four hits in five shutout innings.
Despite his overall career mark, Lauer has had unusual success against the Dodgers dating to his two seasons in San Diego's rotation in 2018-19.
Thursday's game improved his career record against the Dodgers to 6-0 with a 1.89 ERA.
Bauer suffered from lack of run support, working eight innings for the first time this season and allowing only a two-run home run to Travis Shaw in the fourth that proved to be the difference in the game.
The Brewers' win to open the four-game series put them at 15-10 this season, trailing only the Dodgers (16-10) and San Francisco Giants (16-9) among National League teams.
Pitchers' duel in Houston
Yusei Kikuchi was brilliant for the Seattle Mariners against the Houston Astros, allowing one hit and two walks in seven innings while striking out seven in a 1-0 win over the Astros. The Mariners got their only run from a Taylor Trammell homer off Houston starter Luis Garcia in the third inning, and Trammell ended the game with a sliding catch in center field.
The Oakland Athletics split their series against the Tampa Bay Rays with a 3-2 thanks in large part to Matt Chapman, who hit a solo home run in the fourth and added the go-ahead double in the top of the ninth.
In Baltimore, the Orioles bounced back to beat the New York Yankees 4-3 in the 10th inning thanks to a one-out sacrifice fly by Cedric Mullins.
Phillies lose in heartbreaking 10th
The Philadelphia Phillies rallied to send their game with the St. Louis Cardinals to extra innings, but lost 4-3 in the 10th without allowing a hit in the inning. The frame began with Tyler O'Neill on second base thanks to MLB's rule designed to shorten games, and he moved to third on a groundout and scored the winning run on a wild pitch by David Hale.
The Yerminator strikes again
Who else but Yermin Mercedes would cap a White Sox doubleheader sweep of the Detroit Tigers with a monstrous 449-foot home run to center field in Chicago.
