Rapid Reaction: Astros 3, Cubs 0

CHICAGO -- The Chicago Cubs couldn’t avoid the century mark, falling 3-0 to the Houston Astros on Monday at Wrigley Field for their 100th loss of the season.

How it happened: The Cubs were handcuffed on offense in the opener of the final series of the season. They entered the final inning with just two hits, and one of those was from David DeJesus, the first Cubs batter of the game. It was the 15th time the Cubs were shut out this season after not getting their first shutout until May 20.

What it means: It was just the third time in franchise history a Cubs team lost 100 games. No matter what happens over the final two games they won’t match the club record for 103 defeats set in both 1966 and 1962.

Outside the box: Reliever Shawn Camp made his 79th appearance of the season, but remained one behind Dodgers reliever Randy Choate for the most in baseball. Camp, who was considered by manager Dale Sveum to be the Cubs’ first-half MVP, has now pitched 10 consecutive scoreless innings (over 11 outings) going back to an appearance Sept. 2 against the San Francisco Giants.

Off beat: Like leap year, regular-season games in October don’t take place all the time. The current series against the Astros is the first time the Cubs have played a regular-season game in the month at Wrigley Field since 2009 when they went 1-2 against Arizona. The Cubs began play Monday with a 33-27 record in regular-season games at home in October.

Up next: The Cubs will send right-hander Chris Volstad (3-11, 6.64 ERA) to the mound in the middle game of the final series of the season. The Astros will counter with right-hander Bud Norris (6-13, 4.82) in the 7:05 p.m. start from Wrigley Field.
