A big reason for Carlos Beltran's run production with the Mets this season has been a healthy Jose Reyes who is in a contract season of his own.
Reyes, even after the departure of Beltran, is having a good offensive season, leading the league in batting average (.336), and having a productive year all around with 26 doubles, 16 triples and 34 stolen bases so far in 2011.
Reyes' .377 on-base percentage meant that Carlos Beltran often had runners on base while at the plate, resulting in more RBI chances and more RBI for Beltran.
Now that Beltran is with the Giants, the hitters that precede him in the lineup are not at all Reyes-like.
So far this season Giants Manager Bruce Bochy has had Andres Torres and Aaron Rowand platooning in the leadoff spot, mostly due to Torres' injuries this season.
Neither of them is having any success offensively. Following a breakout season in 2010, Torres is hitting just .228 with three home runs, 18 RBI and just a .317 on-base percentage in 2011.
Aaron Rowand is hitting just .235 with four home runs, 21 RBI and a meager .276 on-base percentage.
