ANAHEIM, Calif. (AP) — Two people with knowledge of the trade tell The Associated Press that the Oakland Athletics have acquired infielder 2019 All-Star infielder Tommy La Stella from the Los Angeles Angels for infielder Franklin Barreto.The sources spoke on condition of anonymity Friday night because the clubs hadn't announced the deal.La Stella has a $3.25 million, one-year contract that pays $1,203,704 prorated with the Angels, who acquired him from the Chicago Cubs in November 2018. He is batting .273 with four homers and 14 RBIs this season while playing second base and first base for struggling Los Angeles, which began Friday in last place in the American League.The trade adds another potent veteran bat to the AL West-leading A's, along with depth and versatility at key infield positions. La Stella also was an exceptional pinch-hitter for the Chicago Cubs before emerging as an everyday player with Los Angeles, and that skill could be valuable once again in a postseason run.La Stella became a first-time All-Star at 30 last season with the Angels after a career spent mostly as a pinch-hitting specialist with the Cubs. He didn't get to play in the All-Star Game because he broke his leg on a foul ball shortly after being selected, but he fought to return to the Angels' lineup late in the season.La Stella batted .295 with 16 homers and 44 RBIs in just 80 games last season for the Halos.Barreto has barely played recently for the A's, with the former elite prospect struggling to be consistent in the majors. He is only 0 for 10 at the plate this season with Tony Kemp playing almost every day at second base, although Barreto remains a solid defensive player.Barreto has a $568,500, one-year contract that pays $210,556 prorated. He could be eligible for arbitration for the first time after the 2021 season.Barreto doesn't have a clear role with the Angels, who already have budding star David Fletcher playing every day at second base after shortstop Andrelton Simmons' return from a sprained ankle. Luis Rengifo backs up at both spots.___AP Baseball Writers Janie McCauley and Ronald Blum contributed to this report.___More AP MLB: https://apnews.com/MLB and https://twitter.com/AP_Sports
