Arizona, which has the worst record in the major leagues at 35-79, has lost 24 of its last 28 games and 42 of 51. The Diamondbacks have been outscored 35-13 in their last five games.
Brandon Webb will be trying to avoid his 14th loss for the Diamondbacks. Webb is just 3-13 after going 10-9 last season with a 2.84 ERA in 29 games. He has a 3.68 ERA in 24 starts this year, but poor defense and run support have plagued him all season.
Webb has given up five unearned runs over his last two starts and 22 on the season. The young right-hander, loser of his last nine decisions, hopes the Diamondbacks offense rebounds after a poor performance on Tuesday.
Livan Hernandez and Luis Ayala combined on Montreal’s ninth shutout to lead the Expos over Arizona and Randy Johnson 4-0 Tuesday. Hernandez struck out eight in eight innings, allowing seven hits and two walks. Ayala pitched a one-hit ninth as Montreal won its third straight.
“I wasn’t thinking about a complete game,” said Hernandez, who leads the majors with six. “It’s better to save my arm a little bit.”
Johnson hasn’t won consecutive games since winning six straight from May 18-June 13 and is 1-4 in his last seven starts.
“We haven’t given Randy enough run support,” Diamondbacks manager Al Pedrique said.
Arizona will try to get the bats going against Expos starter John Patterson on Wednesday. Patterson has not qualified for a decision in five starts since coming off the disabled list on July 16. The 26-year-old righty has a 5.01 ERA over that span.
Patterson has walked 13 and yielded six home runs over his last four starts.
The Expos have won 10 of 13 at Olympic Stadium, where they play 27 of their final 51 games.
