With a 9-2 loss to the Astros two days later, the Cubs lost their first series of the season.
For Dierker, 1969 was the peak of a steady career as he posted a 20-13 record and earned a spot on the NL All-Star team. However, it was his only 20-win season. He went on to compile a 139-123 record between 1964-1977.
Holtzman quickly rebounded for a pair of wins on the Cubs' western road trip, raising his record to 9-2. The Cubs are 4-4 so far against Houston, Los Angeles and San Diego. While Chicago may have cooled slightly on this trip, the squad's winning percentage remained a robust .762 for the season.
The Cubs' big three -- Holtzman, Fergie Jenkins (7-3) and Bill Hands (7-1) -- continued to lead the way. Ted Abernathy has three wins and four saves out of the bullpen. Overall, the team ERA stands at 2.34.
Among the Cubs' starters, leading hitters include Glenn Beckert (.337), Billy Williams (.321) and Randy Hundley (.313); RBI leaders Santo (33), Williams (30) and Hundley (18); and top scorers Don Kessinger (30), Beckert (28) and Santo (23). Santo and Willie Smith continue to lead the team in home runs with six apiece, followed by Williams with five.
Next up for the Cubs is a May 25 doubleheader vs. the Padres, then it's on to Candlestick Park for a pair of games against the Giants.

May 23: Cubs reliever Jim Colborn allows a pair of walk-off hits to lose two extra-inning games in two days. Ted Sizemore drove in Paul Popovich with a single for a 4-3 Dodgers win in the bottom of the 12th on May 22. The next day, San Diego's Tommy Dean hit one to the wall in the bottom of the 11th inning, bringing John Sipin all the way around from first base for an 8-7 win. At one point, the Padres trailed 7-1 before tying the game in the eighth, no thanks to Cubs reliever Phil Regan, who continues to struggle out of the bullpen.
