OAKLAND -- What goes up must come down. No one expected the A's to win every single game for the rest of the season, even after tallying nine wins in a row. That being said, the 7-1 loss resulting in the three-game home sweep at the hands of the Angels is mildly troubling. The A's have much more to worry about than Wednesday's loss. The more immediate concern is the health of pitcher Brandon McCarthy after he took a line drive off the head in the fourth inning. Starting Pitching ReportThe ball hit McCarthy just above his right ear. He was eventually able to walk off the field under his own power. According to the A's, McCarthy never lost consciousness and was taken to a local hospital for precautionary reasons.The ball hit by Angels' shortstop Erick Aybar ricocheted off McCarthy to third baseman Josh Donaldson, who threw to first to make the out. After being struck by the liner McCarthy dropped to the ground and laid prone for a moment. Soon after impact the right-handed pitcher was able to sit up and speak with trainer Nick Paparesta. As the Coliseum went completely silent, McCarthy's teammates and coaches stood around him on the mound before he was able to get up and leave the field. McCarthy's ability to leave the field without assistance was an encouraging sign and surely a relief for many. The frightening moment is a reminder just how vulnerable pitchers are when on the mound. On Tuesday night relief pitcher Sean Doolittle was also hit by a line drive. He was struck on the left shin and was reportedly hobbled after the game. McCarthy allowed three runs, all earned, prior to his departure. The runs all came in the third inning. He gave up a leadoff single to Alberto Callaspo, who was moved to third on a sacrifice bunt and a Mike Trout ground out. Callaspo scored on a Torii Hunter single to right field. The next batter was Albert Pujols, who extended his hitting streak to 14 games after he squeezed a double down the third base line that got past a diving Donaldson. The A's chose to take their chances with Howie Kendrick, walking Kendrys Morales to load the bases with two outs. Kendrick came through for the Halos, driving a two-run single to right field, but Morales ran into an out on the play to end the inning. Bullpen ReportTravis Blackley entered in relief of McCarthy. He was given as much time to warm up as needed. The A's long reliever and spot starter kept them in the game. He threw 44 pithes in three innings of scoreless relief. He was able to strand two runners in scoring position in the sixth inning. With runners on second and third with no outs he struck out Mark Trumbo looking and got Aybar to fly out to end the threat. Pat Neshek retired one batter to end the seventh inning. Ryan Cook took over in the eighth frame. He struck out Pujols, walked Morales, then got Kendrick to ground into an inning-ending double play. Cook remained in the game for the ninth, but allowed the Angels to load the bases with no outs.Grant Balfour inherited the bases loaded situation. He walked pinch hitter Maicer Izturis on a close pitch that was called ball four. Balfour responded by striking out Trout looking on a 94-MPH fastball. Hunter then broke open the game with a two-run single up the middle past the outstretched glove of a diving Adam Rosales. Now a 6-1 game, A's manager Bob Melvin brought in Jim Miller. The right-handed pitcher struck out Albert Pujols swinging on a 92-MPH fastball. The Angels then executed a double steal with Hunter taking second and Izturis successfully taking home. Miller eventually ended the inning by getting Morales to ground out to second. At the PlateThe A's put together a third inning rally in response to the Angels' runs. It started with some control problems by Dan Haren. With one out he walked both Derek Norris and Cliff Pennington. The next batter, Coco Crisp, reached on a force attempt after Howie Kendrick didn't even try and touch second after receiving first baseman Kendrys Morales' throw. The Angels argued that Pennington obstructed the throw to no avail. Seth Smith came up next and made the Angels pay for their mistake by driving the first pitch he saw into right field for an RBI single. With the bases loaded Josh Reddick struck out swinging and Yoenis Cespedes grounded out to end the threat. Norris scored the A's first run after a free pass. He ended up with three walks on the day. After Norris' third walk, Brandon Moss entered the game as a pinch hitter and smashed a single to right field. The Angels countered by putting in rookie Nick Maronde. He struck out Crisp and Smith swinging to end the threat. Maronde also struck out Reddick to start the eighth inning. He has retired four batters in his career, all via strikeout. Kevin Jepsen picked up where Maronde left off, striking out Cespedes and Carter to end the eighth inning. A span of five consecutive batters retired via strikeout. In the Field With two on and no outs in the ninth inning, Callaspo laid down a perfect bunt. Donaldson briefly charged the ball before back tracking to third base, while Norris attempted to grab the ball barehanded but couldn't get a grip on it. Norris was charged with an error and the Angels loaded the bases. In the ninth inning with runners on the corners and two outs, the Angels executed a double steal. Miller had the right idea, faking a throw to third as Hunter broke for second, but Drew was late to the bag. As Miller threw the ball to Drew, Izturis broke for home.
