Garcia will look to solve the Angels once again and help the Mariners make up ground in the AL wild-card race when the teams meet in the middle game of their series.
Seattle sits four games behind Oakland in the AL West and 2 1/2 back of Boston for the wild card with five games to play.
Despite its 5-1 victory on Monday, Seattle didn’t make up any ground on either of those teams. The A’s defeated Texas, and Boston beat Baltimore.
“It is pretty apparent what we have to do here, and that is win today and the next day,” said Mariners manager Bob Melvin, whose team won for the fourth time in six games. “We’re at a point now where we need a little help. We have to help ourselves and get help from someone else.”
Garcia is 1-1 with a 0.47 ERA in his last three starts, and is 3-0 with a 1.19 ERA in three starts against the Angels this year. In 15 career starts against Anaheim, he is 10-2 with a 2.46 ERA. The 10 wins are his most against any opponent.
Winn has a seven-game hitting streak, during which the left fielder is batting .407 (11-for-27). Boone is 14-for-32 (.438) over his last eight games.
The defending World Series champion Angels have dropped 10 of 13.
Garret Anderson returned to the lineup after tightness in his lower back forced him to miss his first two games of the season, and went 0-for-4 to snap an eight-game hitting streak.
STANDINGS: Mariners - 2nd place, 4 GB, AL West. Angels - 3rd place, 21 GB, AL West.
MARINERS PROBABLE STARTER: Garcia (12-14, 4.66 ERA). A rain delay forced Garcia to leave his start at Texas on Thursday after four innings, and the Mariners went on to lose 2-1. He gave up one hit, walked one and struck out three. Garcia is in danger of finishing with a losing record for the first time in his five-year career. He won 16 games last year, and is 72-43 overall.
ANGELS PROBABLE STARTER: Scot Shields (4-6, 3.11 ERA). Despite turning in his best performance in more than a month, Shields lost 2-1 to visiting Oakland on Wednesday. The right-hander went a season-high eight innings, giving up two runs and four hits while striking out six. He had allowed at least three runs in each of his previous five starts. Shields is making his first start of the season against the Mariners, after having no record and a 1.80 ERA in four relief appearances against them this year. Shields is 1-0 with a 2.29 ERA in nine games, including one start, against Seattle.
SEASON SERIES: Mariners, 11-6.
