For Patrick Corbin, Monday's finale of the D-backs' four-game series with the Marlins is one of the biggest events in his 22-year-old life -- his debut as a Major League player.

For Mark Buehrle, a 33-year-old veteran who has pretty much done it all and seen it all in 13 Major League seasons, Monday's game is another opportunity to get his Marlins career on the right track in his fifth start of the season.

Corbin arrived in Miami on Sunday fresh off a lights-out four-start performance at Double-A Mobile, but because he was not yet on the D-backs' 25-man roster, he had to watch the game from the stands with general manager Kevin Towers.

On Monday, he will be smack in the middle of the action.

"It's showtime," D-backs manager Kirk Gibson said Sunday. "It's a very exciting time whenever you're making your Major League debut. It's what you dream about, it's what you work hard for. It's what you earn, you earn the opportunity."

Corbin got the opportunity thanks to a strong Spring Training and a 2-0 record and 1.67 ERA through his first four starts at Mobile.

Buehrle comes off a hard-luck loss in New York against the Mets, where he gave up two runs on five hits in seven innings in a 5-1 Marlins defeat. Buehrle is 1-3 with a 2.63 ERA this season after signing with the Marlins in the offseason.

After winning 161 games and pitching two no-hitters, including a perfect game, in 12 seasons with the White Sox, Buehrle has pitched well with little to show for it this season.

The veteran has gone at least six innings in all four of his starts, and his lone win was on April 18, when he gave up one run in eight innings against the Cubs at Marlins Park.

D-backs: Hill extends on-base streak
• Aaron Hill had two hits Sunday and now has reached base safely in 17 straight games and 19 of 21 overall.

• A D-backs victory Monday would give them their first series win since they took two of three from the Padres April 10-12. They won their first two series of the year, then dropped four straight.

Marlins: Multiple walk-offs for Ramirez
• Hanley Ramirez's game-winning hit in Saturday's 3-2 Marlins victory was his second walk-off hit of the season. He also had one April 15 against Houston. Going into Sunday's games, Ramirez was the only player in the Major League with two walk-off hits this season. It marked his third career game-ending hit, with the other on Aug. 7, 2010.

Worth noting
• The D-backs are the lone team in the National League West that Buehrle has never faced.
