The NL West in my opinion has completely transformed over the last let' say 3 weeks. Suddenly the NL "worst" is receiving some attention that is due, not only because the Diamondbacks acquired Adam Dunn, and the Dodgers traded for Manny, but mostly because the division is in an extremely tight race for first place. The way both teams are playing, chances are they could finish close in record, if not better by September's end to that of the NL East winning team. The team that ends up winning the division will if trends continue, win the division by no more than 2-3 games, if even that. The Dodgers suddenly appear to have a transformed offense with Manny's presence, giving batters like Kemp, Eithier, and others better looks at pitches and more strikes to try to avoid having to see Manny step up. The Diamondbacks have also created a similar threat in their lineup with NL HR blaster Adam Dunn. Now its hard to clearly measure if the addition of these 2 players to both ball clubs have created a change, though these statistics could be some proof:
Dodgers since the addition of Manny: Manny has had 14 RBI in 17 games since joining the Dodgers, with that he has also hit 5 HR
With that, the Dodgers are 9-6, but most recently have won 5 of 6.
The Diamondbacks with the addition of Adam Dunn is a little harder to measure since he has not been with the Dbacks nearly as long as Manny has, but the Diamondbacks have had an offense surge with Dunn presence scoring 38 runs in his first 6 games with the team, with the Dbacks winning 4 of 6.
With or without though, both clubs are hitting extremely better since all-star break, and their reputation in the division isn't has harsh as before.
All I know is this, the race will be close, the Diamondbacks have starting pitching and still a better bullpen, though the Dodgers offensively are stronger with quite decent starting pitching, though not as strong as AZ, still effective. The Dodgers have to worry about their bullpen as Sunday we almost saw a 5-1 lead in the 9th end up going to extras. The Diamondbacks have to hope their offense can hold for the pitching, and remember to play fundamental ball until the end.
Should be fun!
