OAKLAND -- Perhaps A's pitcher Jarrod Parker should have considered taking another sick day.
Parker, scratched from his scheduled start Sunday in Texas because of illness, returned to the mound at the Coliseum on Monday night. But things did not go well at all, for him or the A's.
Parker not only saw his streak of 19 consecutive games without a loss come to an end, it was a rude ending in a 12-1 defeat to the Los Angeles Angels before a crowd of 14,629.
Parker (11-7) hadn't lost a game since May 22, a 3-1 loss to the Texas Rangers in Arlington, but this was a quick knockout of the right-hander by the Angels -- two runs in the first, an unearned run in the third and then a big five-spot in the fifth.
The final line wasn't pretty. Parker gave up eight runs -- seven earned -- in 41/3 innings, walking two and striking out three. It was a stark contrast to the pitcher who was 9-0 during the streak and 5-0 with a 2.40 ERA since Aug. 1.
"It was a good run," said Parker. "It was one of those things where all good things come to an end. I guess if you're going to do it, you might as well give it up and get it over with."
Even on such a dour night for Parker and the A's, there was still some good news. With Texas' 6-2 loss to Tampa Bay, Oakland reduced its magic number to clinch the American League West to seven and still leads the division by 61/2 games with 12 to go.
A's manager Bob Melvin said Parker had recovered from whatever bug knocked him for a loop Sunday. But Parker didn't sound as though he was feeling so healthy as he reflected on his performance afterward.
"I'm not going to put it on that or make an excuse, but whatever," he said. "I was throwing up yesterday. I was trying to take liquids and eat and hydrate. I felt better today, and I wanted to keep it going. But I'll just turn the page and move on."
Parker said nothing was working on this night.
"Early in the game, I was all over the place," he said. "It felt like it'd been forever since I was out there. There was very little execution, not too many pitches down in the zone. Even the off-speed was up. It was just not a very good game."
After Parker departed in the fifth, it didn't get any better. Before it was over, young Angels phenom Mike Trout hit perhaps the longest home run of the year at the Coliseum -- a mammoth shot off the window of a luxury suite in straightaway center field against reliever Pedro Figueroa.
Trout's blast was estimated at 421 feet, but without Mount Davis to stop it, the ball surely would have traveled much farther. The ball cleared the center field fence by at least 30 feet and was hit on a line.
"I think Yoenis hit a ball off the glass last year," said Melvin, referring to the A's Yoenis Cespedes. "But he hit it a long way, yeah."
If all that wasn't enough, A's nemesis C.J. Wilson (17-6) did a number on them once again. The left-hander allowed just four hits and one run over seven innings and upped his record to 4-0 against Oakland this season.
The A's recommend that ticket holders enter the stadium gates when they first open to allow ample time for this new security procedure. Gates will open at 5:35 p.m. Thursday, 4:30 p.m. Friday, and 11:05 a.m. on both Saturday and Sunday.
