SF Giants probable pitchers & starting lineup vs. Arizona Diamondbacks, May 12

The Diamondbacks sit behind the Giants in the NL West at the moment. However, the win-loss gap between them and the Los Angeles Dodgers, along with the San Diego Padres, is not that big. The NL West will be a tough division, and this matchup highlights the strength of the division rivals.

Verlander will take the first game of the series against the Diamondbacks. He holds the dubious distinction as the only Giants pitcher in the rotation without a win. The future Hall of Famer is stuck at 262 career wins, but it is not all his fault. The bullpen has been a strength to this roster, but has had some blow ups during Verlander's starts.

The veteran pitcher has a 4.50 ERA in eight starts this season. He has been a lot better lately, recording a 2.70 ERA in his last four outings.

Who is hot for the SF Giants?

Who are the SF Giants facing?
