* The Cubs have yet to win a road series this season, and their 8-17 road record is third worst in baseball. However, they swept their last series at San Francisco, outscoring the Giants 6-3 in the lowest-scoring series ever between Chicago and San Francisco.
* The Giants have the best May record in the NL at 15-7. The last time San Francisco won more than two-thirds of its games in May was 1983 (19-7). The key to San Francisco’s success has been its pitching: the Giants’ 2.83 ERA (65 ER/207.0 IP) leads the majors this month.
* Anthony Rizzo has gone just 2-for-22 (.091) over his last seven games, but he still leads the team and ranks sixth in the league with 84 times on base, thanks in large part to his 37 walks, which lead the NL.
* Michael Morse drove in four runs yesterday, giving him 33 RBI after he had 27 RBI in 88 games last season. Morse’s improvement from 11.6 AB/RBI last season to 5.0 AB/RBI this season is the second-biggest improvement in the NL, minimum 2 PA/team game (Jimmy Rollins).
* Jeff Samardzija’s 1.46 ERA (11/68) is by far the lowest in the last 100 years for a pitcher with no wins in his first 10 starts of a season. The next-lowest ERA since 1914 was Bill Piercy’s 2.69 for the 1923 Red Sox.
* Yusmeiro Petit has faced the Cubs six times in his career, all from 2006-09. In two appearances at Wrigley Field, Petit went 1-0 with a 0.00 ERA, allowing three hits in seven innings. In four home appearances against the Cubs, Petit is 1-1 with a 7.90 ERA (12 ER/13.2 IP).
