BALTIMORE -- For all the good that came out of the Orioles' win in Game 1 -- including a dominant performance from Orioles rookie Zach Britton -- the second portion of Saturday's doubleheader against the Rangers was a 13-1 loss that could hardly have gone any worse.
"I am glad it only counts as one loss," Orioles manager Buck Showalter said. "I kind of dwell on Jake [Arrieta's] really good stuff, and [he] deserved to have a better outing than he did."
Arrieta had one of the worst outings of his career, putting the O's in a hole they couldn't escape in a game marred by the exit of shortstop J.J. Hardy. Hardy left with a left oblique strain and could be placed on the disabled list. The O's bullpen -- saved by Britton's start earlier in the day -- was forced to dip into its reserves early, including Chris Jakubauskas, who was a candidate for Sunday's start because Jeremy Guthrie has been slowed in recent days by pneumonia.
When the dust settled, the Orioles (6-2) had split the doubleheader, but the aftermath of the night game could have a ripple effect.
Arrieta, who won the O's home opener with a strong start on Monday, looked off balance early and struggled to establish any kind of rhythm with catcher Jake Fox, who was making his first start of the season behind the plate.
"They are a very good offensive team," Showalter said of the Rangers, who entered Saturday averaging seven runs per game. "He had some sequences that got a little out of whack and got them on him. And he couldn't quite make that pitch or get the sequences that should have been to get it done."
The 25-year-old Arrieta allowed a career-high eight earned runs over 3 1/3 innings, the second-shortest start of his big league career.
"I've got to develop the rhythm, keep the tempo up," said Arrieta, who agreed that his pitch sequences might have gotten predictable. "When they see guys ahead of them putting good swings on pitches and working the counts, it boosts their confidence."
His undoing was the third inning, in which Arrieta walked two of the bottom three hitters in the Rangers' order and paid dearly for it. Following leadoff hitter Elvis Andrus' two-run single, pitching coach Mark Connor came out for a brief mound meeting to try to get Arrieta back on track. But it was to no avail, because Josh Hamilton followed with a single, and Adrian Beltre followed with a two-run homer to complete the six-run frame.
Arrieta exited after allowing another run in the fourth, courtesy of Mike Napoli's homer. He was charged with his eighth run after reliever Josh Rupe gave up an RBI double to Ian Kinsler. Rupe tossed 2 2/3 innings for the O's and was followed by Jakubauskas' three innings, in which he allowed the Rangers to add on five additional runs.
"Both their guys have good stuff," Rangers infielder Michael Young said of Britton and Arrieta. "The kid in the first game [Britton] had good stuff and the kid in the second game did, too. We just did a better job locking in on the strike zone in the second game and stayed more disciplined within the plate."
The Orioles took an early lead on Adam Jones' homer to open the second. Jones' homer was the only blemish on Rangers lefty Matt Harrison's night, as the lefty tossed seven innings allowing just one other hit.
"It's the same on both sides," Jones said of Saturday's doubleheader. "They lost the first game, we lost the second game. Let's go get the series [on Sunday]."
