On Monday, Detroit Tigers pitcher Justin Verlander offered his fans tickets for his team's opening match against the Kansas City Royals in the upcoming season of Major League Baseball (MLB), but his girlfriend Sports Illustrated model Kate Upton was one of the first ones to react.

Baseball fans only need to tweet Justin their best baseball stories using a simple hashtag to win the tickets.

Tweet me your best baseball stories for a chance to win opening day tickets. Use hashtag #tixfromjv to win!

Kate teased Justin and impishly tweeted out her concern that the Tigers star was giving away her own tickets.

@JustinVerlander are you giving away my tickets?! #tixfromjv

Of course, Kate was just being playful.

Ever since the duo got back together, they have been pictured getting all sweet and cozy several times. Justin and Kate sure don't mind letting everyone know how they enjoy each other's company and just being together. Aside from their numerous outings and dates they have gone out to, they have been exchanging a lot of messages on the social media too. Justin and Kate were first rumoured to have been dating in 2012. During their break, Kate has a relationship with Ukranian dancer Maksim Chmerkovskiy but parted ways eventually before she started seeing Justin again. Maybe, a second time is going to be a charm for Justin and Kate.

The Tigers are set to face the Royals on March 31. According to the official Web site of the Tigers, Justin is the probable pitcher for the game. Justin, who had recently underwent a core muscle repair surgery in January, is doing great in spring training that Kate had even attended in an effort to give inspiration to the baseball pitcher. He appears to be ready for the opening day, reported The Associated Press via Lubbockonline.com. The Tigers just beat the Atlanta Braves, 3-0, on March 21. The six-time All-Star had five hits in five innings and four strikes. Justin will play one more exhibition match before the opening day.

"I feel like my stuff is getting a little better every time out," said Justin.
