Kansas City Royals pitcher Kelvin Herrera will undergo an MRI today after leaving Thursday's game with forearm tightness, The Kansas City Star's Andy McCullough reports.

Herrera, 24, threw five pitches and allowed a leadoff walk to Davide Freese in the seventh inning before leaving the game. In 70 games out of the bullpen this season, he had a 4-3 record with a 1.41 ERA and 59 strikeouts. He is in his fourth season with the Royals after signing with the team as free agent in 2006.

The Royals defeated the Los Angeles Angels 3-2 in 11 innings in Game One of the ALDS on Thursday night. The Kansas City bullpen combined to pitch five shutout innings in relief of starter Jason Vargas. After starting 25 games during the regular season, Danny Duffy pitched the 10th inning and got the win. Closer Greg Holland, who had 46 saves and a 1.44 ERA during the regular season, recorded a save.

Third baseman Mike Moustakas hit the game-winning home run in the top of the 11th for the Royals.

This is Kansas City's first playoff appearance since 1985. The Royals and Angels will play Game Two on Friday at 9:37 p.m. ET.
