The Athletics will be looking for better results on Sunday as they host the Houston Astros in West Sacramento, Calif., with each team vying for its first series win against a divisional opponent in 2026.

It's been a tale of two blowouts so far in this first meeting between American League West rivals this season, with the A's taking the opener 11-4 on Friday night and Houston responding with an 11-0 shutout on Saturday.

Athletics manager Mark Kotsay is looking for a better effort from his team after that big loss.

"We didn't do anything well today," he said postgame on Saturday. "That game was reflective of, in my opinion, past performances that we feel like we have put behind us, and we need to put behind us as a team."

He was critical of the pitching staff's performance after five pitchers combined to give up 18 hits, walk 13 batters and strike out only five.

"This is not reflective of the expectation level of our staff right now," Kotsay said. "We talk about beating ourselves all the time. Today, we completely beat ourselves."

The A's are second in walks in the majors with 47 as a staff in eight games, trailing only the Los Angeles Angels (48). Kotsay said his pitchers need to start locating their offspeed offerings better.

"You've got to be able to keep big-league hitters off-balance," he said. "You've got to have some type of secondary (pitch) you can throw in the zone for a strike and land it and get ahead."

He'll also be hoping for an improvement from Jacob Lopez as he makes his first home start of 2026.

Lopez (0-1, 6.75 ERA) struggled for control as he walked five batters and gave up three runs in four innings of a 4-0 loss to the Atlanta Braves on Monday.

He did not take a decision in either of his previous two career starts against Houston, putting up a 0.87 ERA in 10 1/3 innings, allowing one run on six hits.

If the A's are able to pull out a victory, they will win their first series of the young season after starting 1-5 against the Toronto Blue Jays and Atlanta Braves.

Lance McCullers Jr. (1-0, 1.29 ERA) will take the mound for Houston for the rubber game. McCullers picked up the win in his season debut on Monday against Boston, striking out nine and allowing one run over seven innings. Over 15 starts against the Athletics in his career, McCullers is 7-3 with a 3.32 ERA.

"He kept attacking," Astros manager Joe Espada said after McCullers' outing against the Red Sox. "He set the tone from the very beginning. He was going to control the at-bats."

McCullers has been in the Houston organization for his entire career, drafted in 2012 and debuting in 2015. He was an All-Star in 2017 when the Astros won the World Series, but he has thrown more than 100 innings in a season just once since 2018 while battling multiple injuries. He missed the 2019, 2023 and 2024 campaigns.

He will be looking to build on the work of Tatsuya Imai, who worked 5 2/3 scoreless innings and struck out nine in Houston's win on Saturday to set up Sunday's decisive Game 3.

Last season, the Athletics won the head-to-head series with Houston 8-5.
