Halladay (16-5, 3.22 ERA) has turned in another terrific season for Toronto (74-68) and is poised to capture another Cy Young Award after winning his first in 2003.
Weaver (10-2, 2.16) worked seven innings to win his major league debut with the Angels (76-66) on May 27, and went on to record victories in his first seven starts. He’s been extremely impressive at home, going 4-1 with a 0.90 ERA in six starts at Angel Stadium.
The 23-year-old right-hander bounced back from his shortest outing of the year—when he lasted 4 2-3 innings in a 6-4 loss at Seattle on Aug. 29—to win his outing Monday. Weaver yielded six hits over seven innings in a 1-0 victory over Baltimore.
“Coming off that start last time, I knew that I needed to bounce back and have a good one tonight,” he said. “You’re not going to be perfect every time. You’re going to get banged around, and Seattle got me pretty good. My command wasn’t really that great in that game, so I’m happy to be able to bounce back from that.”
Weaver is facing Toronto for the first time.
Los Angeles remained 5 1/2 games behind first-place Oakland in the AL West after a 2-1 loss to Toronto on Saturday ended a six-game winning streak. The Angels managed only six hits—none after the sixth inning.
Halladay is enduring his longest winless stretch of the season, as he is 0-2 with a 3.52 ERA in his last three starts. He did not receive a decision his last time out when he surrendered one run and five hits over seven innings in a 7-2 loss to Cleveland on Tuesday.
The right-hander is 1-0 with a 2.81 ERA in two starts against Los Angeles this year. He has struggled in his career at Angel Stadium, though, compiling a 1-2 record and an 8.19 ERA in five outings there.
Angels slugger Vladimir Guerrero is 6-for-22 with no extra-base hits in his career against Halladay.
Slumping Chone Figgins batted ninth for the third straight game for Los Angeles and is hitless in six at-bats in this series. Figgins is 5-for-33 against Toronto this year and is 3-for-37 in his last 10 games overall.
Garret Anderson also went 0-for-3 in Saturday’s loss and is just 2-for-18 in five games versus the Blue Jays this season. He’s 8-for-21 with seven RBIs against Halladay in his career.
Toronto improved to 6-3 against Los Angeles this season, clinching the season series with the Angels for the fourth straight year. Gustavo Chacin pitched seven strong innings and Frank Catalonotto doubled in the go-ahead run in the fifth inning.
Catalonotto went 2-for-4 after entering the game with just four hits in 21 at-bats against Los Angeles.
