It was a disappointing start for Weaver, who fell to 12-4 on the year. Half of his losses this season have come at the hands of the Orioles.
Things started out bright for Weaver, as the Angels' offense tallied two runs in the first inning off of Orioles rookie starter Chris Tillman. Vladimir Guerrero swung at a pitch that hopped before it got to him and hit a single to left field, sending Maicer Izturis, who reached on a walk two batters earlier, sprinting around the bases.
The play compounded when Orioles outfielder Felix Pie made an errant throw back to the infield, sending Izturis in to score and putting Guerrero on second. Guerrero scored on the next play on a double by Juan Rivera, giving Weaver an early two-run cushion.
That cushion disappeared in the span of just four batters. After Brian Roberts and Adam Jones reached base to begin the bottom of the first, Aubrey Huff hit a double to left-center, tying the game at 2. Weaver's struggles were just beginning, however.
Baltimore added four more runs in the first inning, forcing Weaver to throw 38 pitches through one frame.
"It's one of those games," Weaver said. "Those guys came out swinging. I didn't have command very much, fell behind and left pitches up so they hit the ball. It's just one of those things where they came out swinging. Our offense did a great job getting us some runs, but you have to tip your hats."
The second inning went smoothly for Weaver, but the right-hander ran into more trouble in the third. Pie hit his third home run of the season, a solo shot, increasing the Halos' deficit to 7-2. After another Orioles run in the fourth, Weaver's day was done. It was the shortest outing this season for Weaver, and the eight runs and four walks were both season highs.
The Nos. 8 and 9 hitters for the Orioles went 7-for-10 Friday, and every Baltimore starter scored at least one run. For Pie, who was in the eighth spot, it didn't matter who was on the mound for the Angels, he was still finding success. Pie set a career high with four hits, and with a two-run triple in the seventh completed just the fourth cycle in Orioles history, joining Huff, Cal Ripken and Brooks Robinson.
The Angels offense attempted a comeback late in the game, however. Gary Matthews hit a double to center field, scoring catcher Mike Napoli from first. Matthews scored on the next at-bat, as Chone Figgins singled to right field, cutting the deficit to 9-5.
Any hope gained from the mini-rally was extinguished during the next half inning, as the Orioles put seven more runs on the board.
For Weaver and the Angels' pitching staff, it's been a season of ups and downs, compounded with injuries to several key starters. Pitchers Kelvim Escobar, John Lackey, Ervin Santana and Joe Saunders have all spent time on the disabled list, with Escobar and Saunders currently inactive.
After the game, Scioscia maintained his level of concern with his pitching staff hasn't increased following Weaver's disappointing outing.
"Pitching is huge for us," Scioscia said. "That's been one frustrating part about where we are at this point in the season, the fact that it's been a little hit-and-miss. But if you look at that core group, those guys all have the potential to be as dominant as they were over the last couple of years. There's a level of concern no matter what your rotation is or what your pitching staff is like."
