Tonight’s the first of two Irish Nights at AT&T Park, and fans with special tickets will receive Irish-themed Giants T-shirts and sit in the Irish Night section.

Even without the special ticket, fans in attendance will get to enjoy Irish-themed pregame and in-game entertainment. There will be another Irish Night, this one with a commemorative cap for those who purchase special tickets, on Aug. 19, kicking off another Heritage Week.

The first 20,000 fans in attendance tonight will receive the third in the “Gamer” poster series, this one featuring Tim Lincecum.

For Tuesday’s game, by the way, there’s another ticketing promotion: Courtesy of Giants broadcasting partner NBC11, view reserved and bleacher seats are only $11. Enter code NBC when purchasing tickets.

I just noticed a new promotion on the schedule for Wednesday: Planet Green Presents: Get Your Green On! Fans who wear green to the game will have a chance to win prizes, and the first 1,000 fans who show proof they took public transit to the game get a reusable fabric grocery bag.
