The A's officially called up pitchers Jesús Luzardo and Daniel Mengden on Monday ahead of their four-game series against the league-leading Houston Astros.
Luzardo, 21, is ranked as the A's top prospect and is considered one of the best pitching prospects in all of baseball. The left-hander threw 91 pitches on Friday for Triple-A Las Vegas, so he doesn't figure to be available until Wednesday, at the earliest. Oakland plans to use Luzardo out of the bullpen down the stretch.
Meanwhile, veteran right-hander Mike Fiers will get the start Monday night as he looks for his 13th straight win, which would tie the Oakland record. The 34-year-old is undefeated in his last 21 starts, already matching the franchise record.
For the season, Fiers is 14-3 with a 3.51 ERA in 29 starts. The former Astro is 1-2 with a 5.63 ERA in seven career starts against Houston.
Fellow right-hander Zack Greinke will take the hill for the Astros. In six starts since joining the club in a trade from Arizona, the 35-year-old is 4-1 with a 3.86 ERA.
Overall this year, Greinke is 14-5 with a 3.09 ERA. He has enjoyed great success against the A's throughout his career, going 7-2 with a 2.97 ERA in 17 outings, including 13 starts.
A's centerfielder Ramón Laureano will miss his second straight game after leaving Saturday's contest with a right leg cramp. He is considered day-to-day. Mark Canha will start in center field and bat fifth.
