For years, Robert Guerrero was among the top fighters in his division, whether it was during his two reigns with a featherweight world title between 2006 and 2008 or when he held a junior lightweight world title in 2009 before moving up in weight.As a lightweight and welterweight, he also made a name for himself, winning interim belts in both weight divisions and facing some of the best opposition around and usually engaging in entertaining fights -- with Joel Casamayor, Michael Katsidis, Selcuk Aydin, Andre Berto and the one and only Floyd Mayweather.However, since beating Berto by decision in a memorable battle in November 2012, Guerreros record has been spotty. He is 2-3 since, with lopsided decision losses to Mayweather and Keith Thurman in welterweight world title bouts and a slightly more competitive decision loss to Danny Garcia for a vacant welterweight belt on Jan. 23, his most recent outing.The two wins came in a hellacious slugfest with Yoshihiro Kamegai and a decision against journeyman Aron Martinez, who dropped Guerrero in the fourth round and lost a split decision in a fight in which many thought Guerrero received a gift from the judges.Now Guerrero (33-4-1, 18 KOs), 33, of Gilroy, California, still with world title aspirations, takes a bit of a step back in terms of his opposition level in an effort to get back on track. He will face unknown David Emanuel Peralta (25-2-1, 14 KOs), who has faced abysmal opposition and will be fighting outside of Argentina for the first time, on Saturday (Spike, 9 p.m. ET/PT) in the 12-round main event of a Premier Boxing Champions tripleheader at the Honda Center in Anaheim, California.There also are two other scheduled 10-round bouts on the telecast. Mexican brawler Alfredo Angulo (24-5, 20 KOs), 33, will face countryman Freddy Hernandez (33-8, 22 KOs), 37, in the co-feature, and 2012 U.S. Olympian Terrell Gausha (18-0, 9 KOs), 28, of Cleveland, will face Steve Martinez (16-2, 13 KOs), 26, of New York City, in the junior middleweight opener.Peralta, who turns 34 on Wednesday, is the epitome of a hand-picked opponent brought in to theoretically make Guerrero look good.Still, Guerrero knows he cannot merely rely on the fact that Peralta, on paper at least, appears to be in way over his head.I got a chance to size him up, Guerrero said at the final news conference Thursday. I saw how tall he is. Picking my spots -- seeing where I have to go. After looking at him, I know hes coming to fight. Im expecting a war. Like all Argentine fighters, I know hes got that hunger to prove hes worthy of this big opportunity and make the most of it.Im focused and the fans can expect to see me leave everything in the ring like always. Ive seen some tape on him. Hes one of those guys that is durable, a durable tall, lanky guy. His height is going to help him. I am expecting a tough fight, for sure. This is like a world title shot for him. I dont know what he is going to bring to the table, and that is exciting for me.Peralta has not boxed in 15 months and is geared up for by far the most significant opponent of his 11-year professional career.This is the biggest fight of my career. It is very important, Peralta said. I have to go out there and put on a great show. I want to go down the same path as [successful countrymen] Marcos Maidana and Lucas Matthysse. They were given great opportunities in their careers and took advantage of them. I am going to take advantage of this opportunity.This is an opportunity to learn. Every fight and fighter is different. I have watched Guerrero fight, but every fighter is different. I have a game plan to beat him. I am well prepared. I came here to fight. I am prepared to go the distance. I am going to throw a lot of punches, move around and be ready to get the decision.Guerrero said he has studied what he could of Peralta, describing him as a laid-back counterpuncher. In other words, Guerrero is going to have to bring the fight to him, which is the way Guerrero likes to fight anyway.Im going to try and execute my game plan. We want to put pressure on him, he said. Ive had really good sparring for this, and Im ready to go. My opponent is kind of a laid-back fighter. Hes going to wait for me to come to him and try to counter. I saw a lot of him lying on the ropes, so Ill come inside and try to give the fans a great performance. Im excited to get in there.Ultimately, what Guerrero wants is another shot at a world title, preferably with Garcia -- although Garcia is in the process of lining up an expected October defense against Berto.Im ready for a world title shot now. I want the Danny Garcia rematch, Guerrero said. I feel like I won the fight. He had some flashy shots, but he didnt want to fight. It is what it is, and it motivates me to get back to that position.Its very important that I win this fight at all cost. The welterweight division has plenty of good fighters that I want to get in the ring with, so its a must that I win this fight. Im not taking Peralta lightly. Im coming to win and win impressively.Peraltas aim is to stop Guerreros quest for that title shot and perhaps get one of his own.Im physically and mentally prepared for this fight. Robert Guerrero is a great fighter and a great champion. Ive seen everything hes done, and I think this is my time, he said. The United States is a beautiful place, and Ive enjoyed being here very much. Im going to give a very hard fight on Saturday night. Im going to leave it all in the ring and come out with a victory.

BALTIMORE -- The Baltimore Orioles keep finding ways to remain in the playoff chase.They recorded shutout victories in the first two contests of this weekend series with the New York Yankees and will try to complete a sweep when the American League East rivals meet on Sunday.The Orioles (74-61) posted an 8-0 and 2-0 victory over the Yankees (69-65) and moved back to within two games of first-place Toronto and Boston.But the Blue Jays have dropped the first two games of their series with Tampa Bay, which let the Orioles pull closer. Theyre also now one game ahead of Detroit in the wild-card race as the Tigers fell on Saturday and three up on Houston, who also lost.Even though the Orioles have experience problems with consistency on offense and pitching, theyve been able to put things together enough times to remain close. They just keep fighting.Very quietly these guys have grinded out the things that theyre good at, Orioles manager Buck Showalter said. Thats why weve got a chance here in September.In this series, Dylan Bundy started and threw 5 2/3 shutout innings Friday while Kevin Gausman blanked New York for six frames the following day. The Orioles havent allowed a run yet in this series.Theyll try to keep rolling on Sunday.Wade Miley (8-11, 5.43 ERA) makes the start for the Orioles. Hes struggled since coming over from the Mariners on July 31 but pitched better in his last few starts, losing 5-1 to the Blue Jays last Monday.Michael Pineda (6-11, 5.112) will go for the Yankees, and hes also run into troubles this season.dddddddddddd The right-hander is winless in his last four starts, going 0-1 with a 4.84 ERA.The Yankees will get more news in a few days on right-hander Chad Green, who started but left Fridays game with elbow pain. They said hes dealing with a sprained right UCL, a strained flexor tendon and is going to see a doctor Monday.Manager Joe Girardi said Green probably wont be pitching for a while, and the Yankees will have to decide what to do when his spot comes up Wednesday.The next couple of days hell just undergo treatment, Girardi said. There could be a number of different scenarios we use Wednesday.Sundays game also is going to be the final one for first baseman Mark Teixeira, who comes from nearby Annapolis, Md., and played his high school baseball about 20 minutes from Camden Yards. Hes retiring after this season.Teixeira still gets regularly booed at the stadium but said it does not worry him.You know, honestly, when you play a long time, it really doesnt bother you at all, Teixeira said. I mean, the fact that they still understand that Im on the field is pretty good considering the season Ive had.Also on Saturday, rookie phenom Gary Sanchez won American League Rookie and Player of the Month honors for August, something no catcher had ever done before.
