He may be only one start into the season, but Mariners right-hander Blake Beavan is already having to remind himself to keep things simple.
Taking a no-decision against the White Sox on Friday in frigid 30-degree weather, Beavan allowed five runs on six hits in five innings. He looked good through the first four innings but unraveled in the fifth, surrendering four runs.
"I was using my fastball to put guys away in the first four innings, and in the fifth inning, I started using breaking balls in those situations and it was unnecessary," Beavan said. "It's just one of those things where you live and you learn.
"I shouldn't have changed what I was doing. It happens to a lot of guys. You just over think things sometimes instead of just sticking with what's working."
Beavan will look to get on track Wednesday at Safeco Field against the Astros, a team he's never faced.
Meanwhile, Brad Peacock makes his second start of the season after laboring through his first outing on Friday against the A's. He should see some added help from an Astros lineup that scored 16 runs in Tuesday's game against the Mariners.
Peacock allowed two runs on three hits in 4 1/3 innings for the loss in his first start since the end of the 2011 season with Washington.
Also walking three in the contest, the right-hander had trouble with his control, getting into too many deep counts that brought his day to an end after 89 pitches.
"With any team, you have to keep the ball down and that's what I have to focus on and make my pitches," Peacock said. "As the starts go on, I'll get more confident, and the biggest key for me is to breathe and calm down out there."
Astros: Porter, Mallee want hitters to work on patience
• Manager Bo Porter said before Tuesday's game that he believes the early-season hitting woes boil down to the Astros needing to be more selective at the plate.
John Mallee, Houston's first-year hitting coach, said the hitters were more patient during Spring Training than they had been in the first week of the regular season.
"We had a pretty good Opening Night, but our strikeouts are up and I think it's because we're chasing a lot early in the count," Mallee said. "We're trying to be more selective now and get better pitches to drive early in the count. I think in the spring we did a really good job of being a little more patient, being ready to hit from the first pitch on, but being selective enough to watch for a pitch we can drive. I think we're getting a little anxious to try to swing our way out of it and started expanding the zone."
Those words must have clicked for the Astros hitters, who had 22 hits in Tuesday's game against the Mariners.
Mariners: Wedge continues to mix up lineup
• Manager Eric Wedge used his ninth different lineup in as many games for Tuesday night's contest against the Astros.
"It's baseball," Wedge said. "You look around the league, and it's not just us. I think people get too caught up, and it's not 1975 anymore. You're not going to have the same nine guys out there every day, and they're not going to stay with the same team for 10 years. It just doesn't work that way.
"The flip side of that is that it's a healthy thing, because we've got 13 guys that we feel like can go out there and play and play regularly if they need to. And it'll definitely help us later in the year, but it's going to help us even here early on as they continue to play and stay fresh. And early on you've got to be careful. You come out of Spring Training where you've got them playing two in a row, three tops, and then you break and you're playing 14 in a row. You've got to be careful with all that, too."
• The Mariners have yet to allow an unearned run this season. Seattle has allowed 39 runs in its first nine games, and all have been earned.
• The Mariners are the only team in the Majors that has yet to enjoy an off-day. The Mariners' first off-day will not be until Monday, a string of 14 games to open the season without a day of rest.
