SAN DIEGO — Manuel Margot hit a three-run home run one batter after a crucial Houston error and made a spectacular catch in right field in his former home ballpark, and the Tampa Bay Rays beat the Astros 4-2 Monday to take a 2-0 lead in the AL Championship Series.

Margot homered off Lance McCullers Jr. with two outs in the first inning on an 87-degree afternoon. An inning later, he tracked George Springer’s long foul ball to right field while shielding his face from the sun and caught it as he tumbled over a padded railing atop a wall and landed on a walkway near the seats down the line at Petco Park.

Margot popped up and held up his glove with the ball in it after a 102-foot sprint. That ended the inning, stranding two runners.

Margot was an outfielder with the San Diego Padres.
